Getting Started

Midtrans mobile SDK enable merchants to accept online payments natively in their mobile apps. We provide two implementation modes: UIKit and CoreKit for making transactions on all payment types supported by Midtrans.

There are five parties involved in the payment process:

1. Merchant Server: The merchant backend implementation
2. Customers
3. Midtrans Backend (Payment Processor)
4. Midtrans Mobile SDK
5. Host App

SDK Implementation Mode

1. UIKit (Recommended) : We provide the drop in User interface for making transactions on all the payment types supported by Midtrans.
2. CoreKit : For advance user, We provide an API only implementation for all payment types, This allows users to bring your own customization of the UI to the mobile app.

SDK Transaction Flow

The general transaction flow of the SDK are shown as diagram below.

1. Checkout: Customer clicks the Checkout button on the Host application and the app makes a request to the Merchant Server
2. Token request: Merchant Server makes a request to Midtrans server with Order Information.
3. Token response: Midtrans responds with a valid transaction token to Merchant server
4. Token response: Merchant server forwards the token to the Mobile SDK
5. Get transaction options: Mobile SDK requests payment/merchant information based on the token
6. Transaction options response: Mobile SDK renders the payment options and payment information to make the payment
7. Pay: Customers selects the payment method and the payment details and clicks “Pay”
8. Charge: Mobile SDK sends the Charge request to the Midtrans Backend for payment Processing.
9. Charge response: Mobile SDK receives the response from Midtrans Backend and triggers the handler on Mobile App with success/failure/pending status
10. Charge notification: Midtrans Backend sends a notification to the Merchant backend confirming the completion of transaction.

However, specifically There are 2 SDK flows based on where the snaptoken (transaction token) is created.

1. SDK Flow : The snaptoken(transaction token) is created from the host app.You need to setup the transaction details (eg: Customer and product details) on the client app for every transaction and send it to the midtrans backend through your merchant server.
2. SnapToken Flow : You have created the snaptoken somewhere else. No transaction setup is needed in the sdk. You can just pass the snaptoken(transaction token) to the API method parameter of the sdk to start the payment directly.

Transaction flow using SDK Flow

1. SDK initialization: Merchant initialize the SDK on the Host App
2. Transaction token request: Merchant prepare a transaction details (order id, gross amount) which can also be added with customer details or item details and pass them as a method parameter on the request transaction token method.
3. Transaction token request: SDK will pass the transaction request body to the merchant server.
4. POST transaction token request: Merchant server will add a Base64 Authorization header to the request body and send it to the merchant secure API.
5. transaction token response: Midtrans API will give back the transaction token response to the merchant server
6. Pass the transcation token: Merchant server will pass the transaction token response to midtrans sdk
7. GET transaction options: SDK will do a GET request to Midtrans secure API for the available transaction options by using the transaction token.
8. transaction options response: Midtrans Secure API will give back transaction options reponse to SDK
9. Display payment list: Mobile SDK receives the response and will display it as a payment list on the Host App.
10. Pay with a selected payment method: Customer can choose the preferred available payment method.
11. Note for number 11.a., These are additional steps only for payment using credit card
    11.a.1 Credit card token request: SDK will do a GET request for a credit card token based on the credit card info
    11.a.2 Credit card token response: Midtrans secure API will give back a credit card token response
    
12. Charge request : SDK will do a POST charge request with the selected payment method to the Midtrans Secure API.
13. Charge response: Midtrans Secure API will give back a charge response

14. Note for number 14.a. These are additional steps only for payment using E-Wallet (ShopeePay, GoPay)
    14.a.1 Open E-Wallet App: SDK will automaticall open the E-Wallet app via deeplink.
    14.a.2 Complete payment on E-Wallet App: Customer complete the payment on the E-Wallet App.

Security Aspects

• There are 2 separate keys CLIENT_KEY and SERVER_KEY (available on MAP)
  • CLIENT_KEY is used for tokenizing the credit card. It can only be used from the Client(mobile device)
  • SERVER_KEY is used for acquiring the token from the Midtrans server. It is not to be used from the device, all API requests that use the SERVER_KEY need to be made from the Merchant Server.
• We use strong encryption for making connections to Merchant server, please make sure it has valid https Certificate.

The following are configurable parameters of SDK that can be used while performing transaction -

1. Merchant server Endpoint / Base URL : URL of server to which transaction data will be sent. This will also be referred to as a merchant server.
2. Transaction details - contains payment information like amount, order Id, payment method etc.
3. Midtrans Client Key - token that is specified by merchant server to enable the transaction using credit card. Available on the MAP

Prerequisites

1. Create a merchant account in MAP
2. In MAP, setup your merchant account settings, in particular the Notification URL.
3. Setup your merchant server. A server side implementation is required for Midtrans mobile SDK to work. You can check the server implementation reference, and walk through the API’s that you may need for implementation on your backend server.
4. Minimum requirements:
   • AndroidSDK: Android 4.0 Ice Cream Sandwich API Level 14
   • iOS SDK: iOS 7 and Xcode 8.0

Merchant Server Implementation

Sample Project to implement Merchant Server sample merchant server.

SDK Changes

There are some changes required on merchant server to make use of the latest SDK.

• 1.0.x SDK needs merchant server to redirect the request to /pay in Snap endpoint.
• 1.1.x SDK needs merchant server to redirect the request to /transactions in Snap endpoint.

Merchants need to implement the following web services for SDK to work correctly. Note the below points, accept and return Content-Type JSON

• Content-Type: application/json
• Accept: application/json

Mandatory

Create Token (Checkout) : This API proxies the request to Snap Backend. This process generates the token necessary for the secure communication between Mobile SDK and Midtrans.

Endpoint: POST on /charge

• Add header in the request.
  • Authorization: Basic Base64(SERVER_KEY:)
• Request will be sent to checkout / create transaction endpoint at Snap Backend.
• Note the above request does not go to api.midtrans.com but to app.midtrans.com
  • Sandbox Endpoint: https://app.sandbox.midtrans.com/snap/v1/transactions
  • Production Endpoint: https://app.midtrans.com/snap/v1/transactions

Optional

We also additionally call a few endpoints if 1-Click or 2-Clicks is enabled :

• To Store Credit Card Tokens: We explicitly invoke POST on /users/<userid>/tokens to allow the backend to store generated credit card token after a successful Credit card charge.
• To Retrieve Credit card Tokens : We explicitly invoke GET GET /users/<user_id>/tokens to retrieve saved card list.

The UserId refers to a generated UUID to associate card collection to each unique user. The mobile SDK generates this UUID during the initialization.

Latest Version

Latest Released version logs on Github release page.

Download Demo App

If you want to have a look at SDK in more convenient manner, you can download latest version of our demo app from Google Play Store. This app is using the latest version of SDK.

Installation

Add SDK installation following into your build.gradle

Midtrans Bintray repository

repositories {
    jcenter()
        // Add the midtrans repository into the list of repositories
        maven { url "http://dl.bintray.com/pt-midtrans/maven" }
        maven { url "https://jitpack.io" }
    }

Sample SDK Sandbox Dependencies

dependencies {
    // For using the Midtrans Sandbox
    implementation 'com.midtrans:uikit:1.26.0-SANDBOX' // change the number to the latest version
  }

Sample SDK Production Dependencies

dependencies {
    // For using the Midtrans Production
    implementation 'com.midtrans:uikit:1.26.0' // change the number to the latest version
}

You need to add Midtrans SDK inside your app’s module build.gradle. Make sure to use the proper environment (SANDBOX / PRODUCTION)

Midtrans SDK Initialization

SdkUIFlowBuilder.init()
        .setClientKey(CLIENT_KEY) // client_key is mandatory
        .setContext(CONTEXT) // context is mandatory
        .setTransactionFinishedCallback(new TransactionFinishedCallback() {
                    @Override
                   public void onTransactionFinished(TransactionResult result) {
                       // Handle finished transaction here.
                   }
                }) // set transaction finish callback (sdk callback)
        .setMerchantBaseUrl(BASE_URL) //set merchant url (required)
        .enableLog(true) // enable sdk log (optional)
        .setColorTheme(new CustomColorTheme("#FFE51255", "#B61548", "#FFE51255")) // set theme. it will replace theme on snap theme on MAP ( optional)
        .setLanguage("en") //`en` for English and `id` for Bahasa
        .buildSDK();

Then you need to initialize it on your activity or application class.

Note:

• CONTEXT: Application/activity context
• CLIENT_KEY: Your midtrans client key (provided in MAP)
• BASE_URL: Your merchant server URL

Differentiate Sandbox and Production in one app (Optional)

Differentiate Sandbox and Production Flavors

android {
  ...
  // Define Merchant BASE URL and CLIENT KEY for each flavors
  productFlavors {
          sandbox {
              buildConfigField "String", "BASE_URL", "\"https://merchant-url-sandbox.com/\""
              buildConfigField "String", "CLIENT_KEY", "\"VT-CLIENT-sandbox-client-key\""
          }

          production {
              buildConfigField "String", "BASE_URL", "\"https://merchant-url-production.com/\""
              buildConfigField "String", "CLIENT_KEY", "\"VT-CLIENT-production-client-key\""
         }
  }
  ...
}

// Define Midtrans SDK dependencies for each flavors
dependencies {
  ...
  sandboxImplementation 'com.midtrans:uikit:1.26.0-SANDBOX' // change the version to latest one
  productionImplementation 'com.midtrans:uikit:1.26.0' // change the version to latest one
  ...
}

You can support two payment environments in your app by defining two flavors in your build.gradle.

Initialize Midtrans SDK using provided base URL and client key in BuildConfig

SdkUIFlowBuilder.init()
        .setClientKey(CLIENT_KEY) // client_key is mandatory
        .setContext(CONTEXT) // context is mandatory
        .setTransactionFinishedCallback(new TransactionFinishedCallback() {
                    @Override
                   public void onTransactionFinished(TransactionResult result) {
                       // Handle finished transaction here.
                   }
                }) // set transaction finish callback (sdk callback)
        .setMerchantBaseUrl(BASE_URL) //set merchant url (required)
        .enableLog(true) // enable sdk log (optional)
        .setColorTheme(new CustomColorTheme("#FFE51255", "#B61548", "#FFE51255")) // set theme. it will replace theme on snap theme on MAP ( optional)
        .buildSDK();

Initialize your SDK using merchant BASE_URL and CLIENT_KEY provided by BuildConfig data.

Let Us Know Your Thoughts

Is our wizard (or setup assistant, using Devsupport AI) helpful? Do you have any feedback? Please share your feedback here.

Prepare Transaction Details

TRANSACTION_ID and TOTAL_AMOUNT are required to create a transaction request for each payment.

Create Transaction Request object

TransactionRequest transactionRequest = new TransactionRequest(TRANSACTION_ID, TOTAL_AMOUNT);

Adding Customer Detail (Optional)

Create CustomerDetails object

CustomerDetails customerDetails = new CustomerDetails();
customerDetails.setCustomerIdentifier("budi-6789");
customerDetails.setPhone("08123456789");
customerDetails.setFirstName("Budi");
customerDetails.setLastName("Utomo");
customerDetails.setEmail("budi@utomo.com");

ShippingAddress shippingAddress = new ShippingAddress();
shippingAddress.setAddress("Jalan Andalas Gang Sebelah No. 1");
shippingAddress.setCity("Jakarta");
shippingAddress.setPostalCode("10220");
customerDetails.setShippingAddress(shippingAddress);

BillingAddress billingAddress = new BillingAddress();
billingAddress.setAddress("Jalan Andalas Gang Sebelah No. 1");
billingAddress.setCity("Jakarta");
billingAddress.setPostalCode("10220");
customerDetails.setBillingAddress(billingAddress);

transactionRequest.setCustomerDetails(customerDetails);

By default, SDK expect you to supply it with customer detail. Customer detail usually consists of first and last name, email, phone number, billing address, and shipping address. For addresses, you can set billing and shipping as one address. If you want to send customer detail to your merchant server during checkout, please create CustomerDetails object and supply it into SDK in Transaction Request object.

If you don’t want to supply customer detail at all, you can use UIKitCustomSetting to skip this process.

NOTE : Before running the project, please make sure that host app doesn’t use action bar in its theme because it will be clash with toolbar used in Midtrans SDK. For example, we can use this config in styles.xml :

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

Item Details

Item details are required for Mandiri Bill and BCA KlikPay payment; it is optional for other payment methods.

ItemDetails class holds information about item purchased by user. TransactionRequest takes an array list of item details.

Item Details Object

ItemDetails itemDetails1 = new ItemDetails(ITEM_ID_1, ITEM_PRICE_1, ITEM_QUANTITY_1, ITEM_NAME_1);
ItemDetails itemDetails2 = new ItemDetails(ITEM_ID_2, ITEM_PRICE_2, ITEM_QUANTITY_2, ITEM_NAME_2);

// Create array list and add above item details in it and then set it to transaction request.
ArrayList<ItemDetails> itemDetailsList = new ArrayList<>();
itemDetailsList.add(itemDetails1);
itemDetailsList.add(itemdetails2);

// Set item details into the transaction request.
transactionRequest.setItemDetails(itemDetailsList);

Note:

• This goes with the assumption that you have created transactionRequest object using required parameters.
• ITEM_NAME maximum character length is 50.

Bill Info

Bill Info is optional for Mandiri Bill payment only.

BillInfoModel class holds information about billing information that will be shown in billing details.

Bill Info object

BillInfoModel billInfoModel = new BillInfoModel(BILL_INFO_KEY, BILL_INFO_VALUE);
// Set the bill info on transaction details
transactionRequest.setBillInfoModel(billInfoModel);

Set Transaction Request into SDK Instance

After creating transaction request with optional fields above, you must set it into SDK instance.

Set Transaction Request into SDK instance

MidtransSDK.getInstance().setTransactionRequest(transactionRequest);

Starting Payment

Starting Payment

CreditCard creditCardOptions = new CreditCard();
// Set to true if you want to save card to Snap
creditCardOptions.setSaveCard(false);
// Set to true to save card token as `one click` token
creditCardOptions.setSecure(false);
// Set bank name when using MIGS channel
creditCardOptions.setBank(BankType.BANK_NAME);
// Set MIGS channel (ONLY for BCA, BRI and Maybank Acquiring bank)
creditCardOptions.setChannel(CreditCard.MIGS);
// Set Credit Card Options
transactionRequest.setCreditCard(creditCardOptions);
// Set transaction request into SDK instance
MidtransSDK.getInstance().setTransactionRequest(transactionRequest);

Start payment method screen

Default mode for Android SDK is showing payment method screen. This screen will show all of your available payment methods.

You can enable/disable payment methods via Snap Preferences in MAP.

Start payment method select screen

MidtransSDK.getInstance().startPaymentUiFlow(ACTIVITY_CONTEXT);

Start payment by using snap token

We provide SDK method to allow you to make payment by using snap token without initialize transaction request first. You just need to pass snap token as argument of startPaymentUiFlow method

Start payment by using snap token

MidtransSDK.getInstance().startPaymentUiFlow(ACTIVITY_CONTEXT, SNAP_TOKEN);

Acquiring Bank

We provide acquiring bank option that can be used to make payment using credit card :

• bca (channel: MIGS)
• bri (channel: MIGS)
• maybank (channel: MIGS)
• bni
• mandiri
• cimb
• danamon
• mega

If you are using bca, bri, or maybank as your acquiring bank (MIGS channel), you have to define its channel explicitly.

Acquiring Bank Configuration

CreditCard creditCardOptions = new CreditCard();
//...
// Set bank name when using MIGS channel. for example bank BRI
creditCardOptions.setBank(BankType.BRI);
// Set MIGS channel (ONLY for BCA, BRI and Maybank Acquiring bank)
creditCardOptions.setChannel(CreditCard.MIGS);
//...

Transaction Finished Callback

In order to get the Transaction Result, you can subscribe for a Transaction Finished Callback by overriding onTransactionFinished method. The method will provide TransactionResult object which has several states.

When response is not null:

• TransactionResult.STATUS_SUCCESS
• TransactionResult.STATUS_PENDING
• TransactionResult.STATUS_FAILED

When transaction is canceled, it can be checked with result.isTransactionCanceled()

When response is null:

• TransactionResult.STATUS_INVALID

Transaction Finish Callback

@Override
    public void onTransactionFinished(TransactionResult result) {
        if (result.getResponse() != null) {
            switch (result.getStatus()) {
                case TransactionResult.STATUS_SUCCESS:
                    Toast.makeText(this, "Transaction Finished. ID: " + result.getResponse().getTransactionId(), Toast.LENGTH_LONG).show();
                    break;
                case TransactionResult.STATUS_PENDING:
                    Toast.makeText(this, "Transaction Pending. ID: " + result.getResponse().getTransactionId(), Toast.LENGTH_LONG).show();
                    break;
                case TransactionResult.STATUS_FAILED:
                    Toast.makeText(this, "Transaction Failed. ID: " + result.getResponse().getTransactionId() + ". Message: " + result.getResponse().getStatusMessage(), Toast.LENGTH_LONG).show();
                    break;
            }
            result.getResponse().getValidationMessages();
        } else if (result.isTransactionCanceled()) {
            Toast.makeText(this, "Transaction Canceled", Toast.LENGTH_LONG).show();
        } else {
            if (result.getStatus().equalsIgnoreCase(TransactionResult.STATUS_INVALID)) {
                Toast.makeText(this, "Transaction Invalid", Toast.LENGTH_LONG).show();
            } else {
                Toast.makeText(this, "Transaction Finished with failure.", Toast.LENGTH_LONG).show();
            }
        }
    }

iOS SDK

Latest Version

Latest released version logs on Github release page.

Installation

Prequisite

Please install Cocoapods version 1.0.0. You can find the installation guide here

Instalation

Installation - Podfile

def shared_pods
    pod 'MidtransCoreKit'
    pod 'MidtransKit'
end

target 'MyBeautifulApp' do
    shared_pods
end

• Navigate to your project’s root directory and run pod init to create a Podfile.
• Open up the Podfile and add MidtransKit to your project’s target.

Installation - install command

pod install --verbose

• Save the file and run pod install to install MidtransKit.
• Cocoapods will download and install MidtransKit and also create a .xcworkspace project.

Initialization

//AppDelegate.m
#import <MidtransKit/MidtransKit.h>

[CONFIG setClientKey:@"VT-CLIENT-sandbox-client-key"
         environment:MidtransServerEnvironmentSandbox
   merchantServerURL:@"https://merchant-url-sandbox.com"];

Once you have completed installation of MidtransKit, configure it with your clientKey, merchant server URL and server environment in your AppDelegate.h

Important: if you use Swift as your project language, you will need to add -ObjC to your Xcode project. Navigate to your .xcodeproj file in Xcode, choose you app main target in Targets, and in Build Settings tab, search for Other Linker Flags, double click and add -ObjC.

Prepare Transaction Details

If you’re using sdkflow, you need to create/generate the transaction token (snaptoken) by providing a transaction details such as:

1. Item details : MidtransItemDetail class is provided to create this object. This class contains item id, item name, item price and item quantity.
2. Customer details : MidtransCustomerDetails class is provided to create this object. This class contains customer first name, last name, email, phone, shipping address and billing address.
3. Transaction details : MidtransTransactionDetails class is provided to create this object. This class contains order id and gross amount. Order id should always be unique for every transaction.

Prepare transaction details

//ViewController.m
MidtransItemDetail *itemDetail =
[[MidtransItemDetail alloc] initWithItemID:@"item_id"
                                      name:@"item_name"
                                     price:item_price
                                  quantity:item_quantity];

MidtransCustomerDetails *customerDetail =
[[MidtransCustomerDetails alloc] initWithFirstName:@"user_firstname"
                                          lastName:@"user_lastname"
                                             email:@"user_email"
                                             phone:@"user_phone"
                                   shippingAddress:ship_address
                                    billingAddress:bill_address];

MidtransTransactionDetails *transactionDetail =
[[MidtransTransactionDetails alloc] initWithOrderID:@"order_id"
                                     andGrossAmount:items_gross_amount];

Starting Payment

There are two ways to start presenting the payment page on the sdk, based on where the snaptoken/transaction token is created.

Start payment by using sdk flow

Present payment page using sdk flow

[[MidtransMerchantClient shared]
 requestTransactionTokenWithTransactionDetails:transactionDetail
 itemDetails:self.itemDetails
 customerDetails:customerDetail
 completion:^(MidtransTransactionTokenResponse *token, NSError *error)
 {
     if (token) {
        MidtransUIPaymentViewController *vc = [[MidtransUIPaymentViewController alloc] initWithToken:token];
        [self presentViewController:vc animated:YES completion:nil];
     }
     else {
         // do something on error
     }
 }];

If you have created the transaction details in the sdk, now all you need to do is call the requestTransactionTokenWithTransactionDetails method, and then present the payment page when the token reponse is retrieved.

Start payment by using snap token on iOS

From iOS SDK v1.12.0, we provide SDK method to allow you to make payment by using snap token without initialize transaction details. You just need to pass snap token as argument of requestTransacationWithCurrentToken: method

Present payment page using SNAPtoken

[[MidtransMerchantClient shared] requestTransacationWithCurrentToken:{{string token}}
    completion:^(MidtransTransactionTokenResponse * _Nullable regenerateToken, NSError * _Nullable error) {
        MidtransUIPaymentViewController *paymentVC = [[MidtransUIPaymentViewController alloc] initWithToken:token];
        paymentVC.paymentDelegate = self;
        [self.navigationController presentViewController:paymentVC animated:YES completion:nil];
}];

Transaction Callback / Delegates

Conform with MidtransUIPaymentViewControllerDelegate

//ViewController.m

#import <MidtransKit/MidtransKit.h>

@interface ViewController () <MidtransUIPaymentViewControllerDelegate>
//other code

SDK will give callback/ delegate transaction response to host app. To be able to do so, please follow these steps:

• Set your view controller to conform with MidtransUIPaymentViewControllerDelegate

Set the delegate

//ViewController.m

MidtransUIPaymentViewController *vc = [[MidtransUIPaymentViewController alloc] initWithToken:token];
//set the delegate
vc.paymentDelegate = self;

• Set the delegate of MidtransUIPaymentViewController

Implement the functions of delegate

//ViewController.m

#pragma mark - MidtransUIPaymentViewControllerDelegate

- (void)paymentViewController:(MidtransUIPaymentViewController *)viewController paymentSuccess:(MidtransTransactionResult *)result {
    NSLog(@"success: %@", result);
}

- (void)paymentViewController:(MidtransUIPaymentViewController *)viewController paymentFailed:(NSError *)error {
    NSLog(@"failed: %@", error);
}

- (void)paymentViewController:(MidtransUIPaymentViewController *)viewController paymentPending:(MidtransTransactionResult *)result {
    NSLog(@"pending: %@", result);
}

- (void)paymentViewController_paymentCanceled:(MidtransUIPaymentViewController *)viewController {
    NSLog(@"canceled");
}

//This delegate methods is added on ios sdk v1.16.4 to handle the new3ds flow
- (void)paymentViewController:(MidtransUIPaymentViewController *)viewController paymentDeny:(MidtransTransactionResult *)result{
    NSLog(@"Deny %@", result);
}

• Implement the MidtransUIPaymentViewControllerDelegate functions

The 5 mandatory delegate functions that are required to implement:

1. paymentSuccess : handle your successful transaction here
2. paymentPending : handle pending transaction here, for async payment, the last status that the sdk recieved will be here as pending.
3. paymentFailed: handle your failed transaction here, this method will give error as a result.
4. paymentCanceled: handle canceled transaction here, this is called only when customer closes the Payment Page of Midtrans SDK UIKit.
5. paymentDeny(Note This delegate method is added starting on ios sdk v1.16.4 to handle the new3ds flow) : handle your denied transaction here, especially for credit card payment.

The 2 optional delegate functions:

1. saveCard: to check if saved card for credit card is successfull
2. saveCardFailed : to check if saved card for credit card is failed

Features

Two Clicks Payment

Two clicks feature allows you to capture the customer’s card number, expiry date, email and phone number as a TWO_CLICKS_TOKEN. For successive payments by the same customer, the TWO_CLICKS_TOKEN can be utilized to pre-fill the details. The customer just needs to fill out the cvv number to finish the payment. By default this SDK will use Midtrans token storage to save customer credential so you don’t need to setup anything on your backend.

Please see the configuration on the example code to enable the two clicks mode.

CreditCard creditCardOptions = new CreditCard();
// Set to true if you want to save card as two click payment
creditCardOptions.setSaveCard(true);
// Set Credit Card Options
transactionRequest.setCreditCard(creditCardOptions);
// Set transaction request into SDK instance
MidtransSDK.getInstance().setTransactionRequest(transactionRequest);

// You can set Authentication.AUTH_3DS / Authentication.AUTH_RBA / Authentication.AUTH_NONE

CC_CONFIG.paymentType = MTCreditCardPaymentTypeTwoclick;
CC_CONFIG.saveCardEnabled = YES;

To enable two clicks in the SDK, you’ll need to:

1. enable saved card

SdkUIFlowBuilder.init(CONTEXT, CLIENT_KEY, BASE_URL, CALLBACK)
                    // disable built in token storage
                    .useBuiltInTokenStorage(false)
                    .buildSDK();

One Click Payment

In addition to two clicks feature, SNAP also supports one click transaction which will also capture the card’s cvv. With this, customers can directly proceed to pay without input any information.

to enable one click in the SDK, you’ll need to:

1. enable saved card
2. enable 3ds.

One click payment configuration

CreditCard creditCardOptions = new CreditCard();
// Set to true if you want to save card as one click
creditCardOptions.setSaveCard(true);
// Set secure option to enable or disable 3DS secure
creditCardOptions.setAuthentication(Authentication.AUTH_3DS);
// Set Credit Card Options
transactionRequest.setCreditCard(creditCardOptions);
// Set transaction request into SDK instance
MidtransSDK.getInstance().setTransactionRequest(transactionRequest);

CC_CONFIG.paymentType = MTCreditCardPaymentTypeOneclick;
CC_CONFIG.saveCardEnabled = YES;
//1-click need 3ds enabled
CC_CONFIG.authenticationType = MTAuthenticationType3DS;

To ease card saving process, SNAP provides card token storage feature. So, merchants don’t have to store and manage credit card token by themselves. Merchants can easily integrate credit card token storage feature to SNAP by providing unique user_id that associates with customers’ account on merchant’s system, in addition to enabling credit_card.save_card flag.

SNAP will then decide to store credit card token as one click token based on two criteria:

• Merchant has recurring MID enabled
• Initial transaction is 3DS-enabled

Installment

Prerequisites

There are few things that needs to be checked before installment can be used.

1. MID for installment must be activated (please contact support@midtrans.com to activate MID)
2. Setup merchant server to handle checkout request. (Please see this wiki)

Enable installment & add terms

Installment installment = new Installment();

Map<String, ArrayList<Integer>> bankTerms = new HashMap<>();
ArrayList<Integer> termBri = new ArrayList<>();
termBri.add(3);
termBri.add(6);
termBri.add(12);
//set bank and term
bankTerms.put("bri", termBri);

ArrayList<Integer> termOffline = new ArrayList<>();
termOffline.add(3);
termOffline.add(6);
termOffline.add(12);
//set bank and term
bankTerms.put("offline", termOffline);

installment.setTerms(bankTerms);
installment.setRequired(true);

// assume you already declare CreditCard() as creditCard
creditCard.setInstallment(installment);

// assume you already declare TransactionRequest() as transactionRequest then assign to TransactionRequest
transactionRequest.setCreditCard(creditCard)

NSDictionary *terms = @{@"offline": @[@3, @6, @12],
                        @"bni": @[@6, @12]
                        };
CC_CONFIG.predefinedInstallment = [MidtransPaymentRequestV2Installment modelWithTerms:terms isRequired:YES];

Setup the SDK

Before request token, enable installment and add your installment terms

• required –> the installment payment required.
• terms -> array of available installment terms of supported bank.

Setup whitelist bins

// assume you already declare CreditCard() as creditCard
ArrayList<String> whiteList = new ArrayList<>(Arrays.asList("493496","451197","493497","493498"));
creditCard.setWhiteListBins(whiteList);
// assume you already declare TransactionRequest() as transactionRequest then assign to TransactionRequest
transactionRequest.setCreditCard(creditCard)

NSArray *whitelistBins = @[@"493496", @"451197", @"493497", @"493498"];
[[MidtransMerchantClient shared] requestTransactionTokenWithTransactionDetails:trx
                                                                   itemDetails:<item details>
                                                               customerDetails:<customer details>
                                                                   customField:<custom field>
                                                                     binFilter:whitelistBins
                                                            blacklistBinFilter:<blacklist bins>
                                                         transactionExpireTime:<expire time>
                                                                    completion:^(MidtransTransactionTokenResponse * _Nullable token, NSError * _Nullable error)

 {
     if (error) {
     }
     else {
     }
 }];

Optionally whitelist_bins can be used to accept only card numbers within the specified BIN numbers. (whitelist_bins is required for offline installment type).

Mobile SDK and Midtrans backend (snap) will check if the card numbers’ first n digit numbers contain one of bins available in whitelist_bins.

This installment object and whitelist bins need to be added at credit_card object when the server accepts the transaction request from mobile SDK. A full example of installment data sent to Snap is like this.

BNI Point

BNI Point is special feature for BNI Bank customers. This feature allows users to redeem their point to be applied into their credit card payments. In your app side, there’s no adjustment needed. To enabled this feature in mobile SDK you just need to contact our support team. Please have a look to the following BNI Point flow to know more about this feature.

Mandiri Fiestapoin

Mandiri Fiestapoin is special feature for Mandiri Bank customers. This feature allows users to redeem their Mandiri fiestapoin to be applied into their credit card payments. In your app side, there’s no adjustment needed. To enabled this feature in mobile SDK you just need to contact our support team.

Risk Based Authentication (RBA)

Set up RBA

CreditCard creditCard = new CreditCard();
// ....
// make set authentication to RBA
creditCard.setAuthentication(Authentication.AUTH_RBA);

// Set into transaction Request
TransactionRequest transactionRequest = MidtransSDK.getInstance().getTransactionRequest();
transactionRequest.setCreditCard(creditCard);

// You can set Authentication.AUTH_3DS / Authentication.AUTH_RBA / Authentication.AUTH_NONE

CC_CONFIG.authenticationType = MTAuthenticationTypeRBA;

RBA is a program from VISA for merchants to be able to route each of their transactions to use 3DS MID or non-3DS based on their risk level.

Under RBA program, VISA wish to help merchants to protect their transactions without sacrificing their conversion rate due to known issues in current 3DS (delayed/unsent OTP, connection, etc).

Example: Use 3D secure if customer is using US card and did more than 3 transactions in the last 1 hour. Use non 3D Secure if customer is using Indonesia card and amount is less than 100,000.

This feature can be activated by contacting our support team. Then you need to configure the SDK to use this feature.

Pre Authorization

Set up authorize transaction

CreditCard creditCard = new CreditCard();
creditCard.setType(CardTokenRequest.TYPE_AUTHORIZE);

// Set into transaction Request
TransactionRequest transactionRequest = MidtransSDK.getInstance().getTransactionRequest();
transactionRequest.setCreditCard(creditCard);

// Set into SDK instance
MidtransSDK.getInstance().setTransactionRequest(transactionRequest());

CC_CONFIG.preauthEnabled = YES;

Pre Authorization is a feature to set the credit card transaction type into authorize. If the transaction type is authorize then the merchant needs to capture the payment in MAP. To use this feature you need to add a settings into the credit card options in transaction request.

Direct payment screen

Start Direct Payment Screen

startPaymentUiFlow(CONTEXT, PAYMENT_METHOD)

// or run the SDK by using snap token
startPaymentUiFlow(CONTEXT, PAYMENT_METHOD, SNAP_TOKEN)

// example : credit card payment
MidtransSDK.getInstance().startPaymentUiFlow(MainActivity.this, PaymentMethod.CREDIT_CARD);

// example : credit card payment
MidtransUIPaymentViewController *paymentVC =
[[MidtransUIPaymentViewController alloc] initWithToken:token
                andPaymentFeature:MidtransPaymentFeatureCreditCard];

Users can directly go to payment screen and skip the default payment method screen.

Note:

• Please make sure the payment method is activated via Setting -> Snap Preferences in MAP.
• For other payment methods you just need to change the parameter of payment method.
• For GO-PAY integration in iOS please see section GO-PAY CONFIGURATION IOS

// -----------------------
// GO-PAY CONFIGURATION IOS

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>gojek</string>
</array>

We provide a method API to make direct payment for all payment methods on Android and iOS SDK.

Note: Below direct payment methods are currently deprecated for Android:

1. PaymentMethod.XL_TUNAI
2. PaymentMethod.KIOSON
3. PaymentMethod.GIFT_CARD_INDONESIA
4. PaymentMethod.INDOSAT_DOMPETKU

Gopay IOS Configuration

Gopay transaction is happened through the Gojek app. For IOS, In order to detect and open the Gojek app, it’s required to add the LSApplicationQueriesSchemes key to your app’s Info.plist.

// Gopay ios config to detect and open gojek app

<key>LSApplicationQueriesSchemes</key>
<array>
  <string>gojek</string>
</array>

Using Callback Deeplink

You can enable callback deeplink, which enable users to go back to the host app after completing gopay payment in Gojek app. You need to implement the deeplink callback by adding your app url schemes. There’re two ways to do this, You can either:

1. Go to Project Settings -> Info, and add inside The URL Types section a new URL scheme. For example you can add something like myApp or any name you preferred.
2. Alternatively you can go to your info.plist file and paste this code, you can change myApp value to any name you preferred for your app.

// Add url scheme to your app
// You can replace myApp to your preferred app name.

// CAUTION: Don't ever use gojek as the name in your url scheme because it will interfere with the functionality

<key>CFBundleURLTypes</key>
    <array>
        <dict>
            <key>CFBundleTypeRole</key>
            <string>Editor</string>
            <key>CFBundleURLSchemes</key>
            <array>
                <string>myApp</string>
            </array>
        </dict>
    </array>

CAUTION: Don’t ever use gojek as the name in your url scheme because it will interfere with the functionality.

Afterwards, you need to configure it in the sdk based on your url scheme name.

//configure your url scheme to the sdk config

MidtransConfig.shared.callbackSchemeURL = @"myApp://";

Without callback deeplink

Alternatively if you want to check your transaction status manually, you can do it by calling this method:

// iOS without callback deeplink implementation

NSString *token = [[NSUserDefaults standardUserDefaults] objectForKey:MIDTRANS_CORE_CURRENT_TOKEN];

[[MidtransMerchantClient shared] performCheckStatusTransactionWithToken:token completion:^(MidtransTransactionResult * _Nullable result, NSError * _Nullable error) {
    if (!error) {
        if (result.statusCode == 200) {
            //handle success
        }
    } else {
        //handle error
    }
}];

Gopay Android Configuration

If you use GO-PAY payment method, There are two ways to get the result of the transaction:

1. First, the easy one is with callback deeplink (go back to host-app)
2. Alternatively you can also do it without callback deeplink.

If you want to use callback deeplink to get the result from GO-JEK app, please set your deeplink on the TransactionRequest object that you’ve created, please refer to this link for deeplink implementation. If your app don’t use deeplink, you can skip this step and check your transaction manually.

For example if you set your deeplink like this demo:://midtrans then GO-JEK app will return callback like this for success demo://midtrans?order_id=xxxx&result=success and this for failure demo://midtrans?order_id=xxxx&result=failure.

Note:

• Please make sure the payment method is activated via Setting -> Snap Preferences in MAP.
• Using deeplink only work with latest GO-JEK application.
• For more GO-PAY integration please refere to this link for Android.

Using callback deeplink

// Setup your Transaction Request here then set your GO-PAY deeplink.
// Assume you already make TransactionRequest object.
transactionRequest.setGopay(new Gopay("demo://midtrans"));

Without callback deeplink

// You don't need special setting for this implementation. 
// For checking transaction status, you can call getTransactionStatus method for checking.
String snapToken = getMidtransSDK().readAuthenticationToken();
MidtransSDK.getInstance().getTransactionStatus(snapToken, new GetTransactionStatusCallback() {
            @Override
            public void onSuccess(TransactionStatusResponse response) {
                // do action for response
            }

            @Override
            public void onFailure(TransactionStatusResponse response, String reason) {
                // do nothing
            }

            @Override
            public void onError(Throwable error) {
                // do action if error
            }
        });

ShopeePay Callback Deeplink

ShopeePay transaction is happened through the Shopee App. You must enable deeplink, which enable users to go back to the host app after completing ShopeePay payment in Shopee app.

1) For ios, to enable deeplink you need to setup the url scheme in your plist file. However if you already implement it for GoPay, then you don’t need to setup the url scheme again, you are already good to go. You just need to directly setup the ShopeePay callback url value on the SDK Config based on your url scheme name.

// Add url scheme to your app
// You can replace myApp to your preferred app name.
// If you already set this for GoPay in your app, then you don't need to do this again


// CAUTION: Don't ever use gojek as the name in your url scheme because it will interfere with the functionality

<key>CFBundleURLTypes</key>
    <array>
        <dict>
            <key>CFBundleTypeRole</key>
            <string>Editor</string>
            <key>CFBundleURLSchemes</key>
            <array>
                <string>myApp</string>
            </array>
        </dict>
    </array>

//configure your url scheme to the sdk config

MidtransConfig.shared.shopeePayCallbackURL = @"myApp://";

2) For Android, please set your deeplink on the TransactionRequest object that you’ve created, please refer to this link for deeplink implementation.

For example if you set your deeplink like this demo:://midtrans then Shopee app will return callback like this demo://midtrans. To get the transaction status, you can get from the SDK callback (Refer to Gopay Android Configuration)

//Add intent filters for incoming links
//If you already do this for GoPay, you don't need to set this again.

<activity android:name=".EntryActivity"
    android:launchMode="singleTask">
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />

        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />

        <data
            android:host="midtrans"
            android:scheme="demo" />
    </intent-filter>
</activity>

// Setup your Transaction Request here then set your ShopeePay deeplink.
// Assume you already make TransactionRequest object.
transactionRequest.setShopeepay(new Shopeepay("demo://midtrans"));

Card Registration is a feature to allow customers to save credit card token without doing transactions first. This feature is provided for merchants that will make API-to-API payments. To implement it, you just need to follow the sample code.

Notes:

• Card expiry consists of expiryMonth and expiryYear. Both are String and should follow this format : 2 digit for expiryMonth (for example : “02”), and 4 digit for expiryYear (for example : “2020”).
• CVV is String too, with number of digit between 3 or 4, based on card. Mastercard, Visa, or JCB usually has 3 digit CVV, while American Express has 4.
• Number of digit for expiryMonth (example : it must be 2 digits) Reason : there is an error while merchant try to input 1 digit for this parameter, but there is no clue what’s gone wrong regarding the code.
• Number of digit for expiryYear (example : it must be 4 digits)
• Number of digit for cvv (example : it must be 3 digits)

Custom Expiry

There is a feature on mobile SDK to enable custom transaction lifetime. To use this feature you need to add an ExpiryModel object into TransactionRequest.

Custom Expiry Configuration

// set expiry time
ExpiryModel expiryModel = new ExpiryModel();

// set start time
long timeInMili = System.currentTimeMillis();
// format the time
DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss Z");
df.setTimeZone(TimeZone.getTimeZone("Asia/Jakarta"));
// format the time as a string
String nowAsISO = df.format(new Date(time));
// set the formatted time to expiry model
expiryModel.setStartTime(Utils.getFormattedTime();
expiryModel.setDuration(1);
// set time unit
expiryModel.setUnit(ExpiryModel.UNIT_MINUTE);
//set expiry time object to transaction request
transactionRequest.setExpiry(expiryModel);

   MidtransTransactionExpire *expireTime = [[MidtransTransactionExpire alloc] initWithExpireTime:nil expireDuration:1 withUnitTime:MindtransTimeUnitTypeHour];

// and then
[[MidtransMerchantClient shared] requestTransactionTokenWithTransactionDetails:trx
                                                                       itemDetails:@[itm]
                                                                   customerDetails:cst
                                                                       customField:arrayOfCustomField
                                                                         binFilter:binFilter
                                                                blacklistBinFilter:blacklistBin
                                                             transactionExpireTime:expireTime
                                                                        completion:^(MidtransTransactionTokenResponse * _Nullable token, NSError * _Nullable error)

Parameter	Description
start_time
String(255) (optional)	Timestamp in yyyy-MM-dd HH:mm:ss Z format. If not specified, transaction time will be used as start time (when customer charge)
duration
Integer (required for expiry)	Expiry duration
unit
String (required for expiry)	Expiry unit. Options: day, hour, minute (plural term also accepted)

Custom Field

Set up custom field

TransactionRequest transactionRequest = MidtransSDK.getInstance().getTransactionRequest();
transactionRequest.setCustomField1(CUSTOM_FIELD_1);
transactionRequest.setCustomField2(CUSTOM_FIELD_2);
transactionRequest.setCustomField3(CUSTOM_FIELD_3);
MidtransSDK.getInstance().setTransactionRequest(transactionRequest);

    NSMutableArray *arrayOfCustomField = [NSMutableArray new];
    [arrayOfCustomField addObject:@{MIDTRANS_CUSTOMFIELD_1:@"custom134"}];
    [arrayOfCustomField addObject:@{MIDTRANS_CUSTOMFIELD_2:@"custom3332"}];
    [arrayOfCustomField addObject:@{MIDTRANS_CUSTOMFIELD_3:@"custom3333"}];

// and then
 [[MidtransMerchantClient shared] requestTransactionTokenWithTransactionDetails:self.transactionDetails
                                                                       itemDetails:self.itemDetails
                                                                   customerDetails:self.customerDetails
                                                                       customField:arrayOfCustomField
                                                             transactionExpireTime:nil
                                                                        completion:^(MidtransTransactionTokenResponse * _Nullable token, NSError * _Nullable error)
     {
         ...
}];

These 3 fields will be brought at payment so it will be available at MAP and a HTTP notification will be sent to the merchant.

Custom VA Number

Set up Custom VA Number

// ....
// Custom VA Number Permata Bank
TransactionRequest transactionRequest = MidtransSDK.getInstance().getTransactionRequest();
// custom va number for Permata Bank Transfer must be 10 digits
String PERMATA_VA_NUMBER = "1234512345";
// Set into transaction Request
transactionRequest.setPermataVa(new BankTransferRequestModel(PERMATA_VA_NUMBER));

// ....
// Custom VA Number BCA Bank
TransactionRequest transactionRequest = MidtransSDK.getInstance().getTransactionRequest();
// custom va number
String BCA_VA_NUMBER = "1234512345";
// Set into transaction Request
transactionRequest.setBcaVa(new BankTransferRequestModel(BCA_VA_NUMBER));
// ...

// ....
// Custom VA Number BNI Bank
TransactionRequest transactionRequest = MidtransSDK.getInstance().getTransactionRequest();
// custom va number
String BNI_VA_NUMBER = "1234512345";
// Set into transaction Request
transactionRequest.setBniVa(new BankTransferRequestModel(BNI_VA_NUMBER));
// ...

CONFIG.customBCAVANumber = @"your va string";
CONFIG.customPermataVANumber = = @"your va string";

Mobile SDK provides a feature that allows customized VA Number for the following payment methods - Permata VA (Bank Transfer) - BCA VA (Bank Transfer) - BNI VA (Bank Transfer)

Note - The Custom VA number must consist of numbers. - Custom VA Number for Permata Bank Transfer must be 10 digits

Other Bank ATM / VA Switcher

For bank transfers beside BCA, Mandiri, BNI, or Permata, Midtrans previously utilized Permata as VA processor. Recently, Midtrans adds support for BNI VA, giving the merchant flexibility to choose which one will be used for other bank transfer. The idea is when one of the processors (either BNI or Permata) is down, merchant can switches to other processor, preventing lose of the sales. In order to use this functionality, merchant should enable both BNI VA and Permata VA. The switch itself is located in Snap Preferences in MAP (Merchant Administrator Portal). In merchant app, there’s no adjustment needed. The changes will be valid for the next checkout.

Sub Company Code

Set up sub company code for BCA VA

// ....
// Transaction request
TransactionRequest transactionRequest = MidtransSDK.getInstance().getTransactionRequest();
// sub company code must be exactly 5 digits of number
String SUB_COMPANY_CODE_BCA = "12321";
// Create BcaBankTransferRequestModel object and then set the SUB_COMPANY_CODE_BCA  
BcaBankTransferRequestModel bcaRequestModel = new BcaBankTransferRequestModel();
bcaRequestModel.setSubCompanyCode(SUB_COMPANY_CODE_BCA);
// Set into transaction Request
transactionRequest.setBcaVa(bcaRequestModel);

// sub company code must be exactly 5 digits of number ex:55555
CONFIG.customBCASubcompanyCode = @“55555”;

This feature allows you to pass sub company code in VA payment. The sub company code must be exactly 5 digits of number. This feature is only available on BCA VA payment method.

Custom Recipient

Set up Custom Recipient for Permata

// ....
// Custom Recipient Name for Permata Bank
TransactionRequest transactionRequest = MidtransSDK.getInstance().getTransactionRequest();
// custom recipient for Permata Bank Transfer must be 20 character at most and in uppercase
String PERMATA_RECIPIENT = "SUDARSONO";
// Create request model (you can optionally insert custom VA as method argument here)
PermataBankTransferRequestModel permataRequest = new PermataBankTransferRequestModel();
permataRequest.setRecipientName(PERMATA_RECIPIENT);
// Set into transaction Request
transactionRequest.setPermataVa(permataRequest);

Mobile SDK provides a feature that allows merchant to customize recipient name for Permata VA (Bank Transfer). The recipient name will be displayed in the ATM screen.

Note - The custom recipient name must consist of alphanumeric characters and space. No symbol allowed. - Custom recipient name for Permata Bank Transfer must be 20 characters at most, and in uppercase.

Custom Themes

Set up Custom Fonts & Theme Color

/**
 * Android custom font
 */

MidtransSDK midtransSDK = MidtransSDK.getInstance();
midtransSDK.setDefaultText("open_sans_regular.ttf");
midtransSDK.setSemiBoldText("open_sans_semibold.ttf");
midtransSDK.setBoldText("open_sans_bold.ttf")

/**
 * Android custom theme color
 */

// Create Custom Color Theme
String examplePrimary = "#ffffff";
String examplePrimaryDark = "#ffffff";
String exampleSecondary = "#ffffff";
CustomColorTheme colorTheme = new CustomColorTheme(examplePrimary, examplePrimaryDark, exampleSecondary);

// Set Theme color into SDK Builder
SdkUIFlowBuilder.init(this, BuildConfig.CLIENT_KEY, BuildConfig.BASE_URL, this)
                    .setColorTheme(colorTheme)
                    .build();

// or
// Set Theme color into Initialized SDK
MidtransSDK midtransSDK = MidtransSDK.getInstance();
midtransSDK.setColorTheme(colorTheme)

// Set Fonts & Theme color into Initialized SDK
MidtransUIFontSource fontSource =
[[MidtransUIFontSource alloc] initWithFontNameBold:font_name
                                   fontNameRegular:font_name
                                     fontNameLight:font_name];
[MidtransUIThemeManager applyCustomThemeColor:themeColor
                                    themeFont:fontSource];

Mobile SDK provide Fonts and Theme color customization.

• Custom Fonts : to set your fonts to SDK you have to add the font to your project.
• Custom Theme Color : By default, SDK will use color settings provided in Snap Preferences in MAP. If you want to use your own custom theme color you need to define it in SDK.

Android Custom Themes

Android Custom Fonts

To use a custom font on Android SDK, you need to put your font files to assets directory of project and then just follow the sample code.

Notes:

• (Android) open_sans_regular.ttf, open_sans_semibold.ttf, open_sans_bold.ttf are path of the custom font on the assets directory.

Android Custom Theme color

To set custom theme in this SDK you just need to provide 3 colors:

• Primary: For top panels showing amount
• Primary Dark: For bordered button, link button
• Secondary: For text field.

iOS Custom Themes

We’ve created MidtransUIThemeManager to configure the theme color and font of the Midtrans payment UI.

Class MidtransUIThemeManager needs UIColor object so you need to convert your HEX or RGB to UIColor, here is a nice tool to generate UIColor code.

Note: If you didn’t configure this MidtransUIThemeManager, your theme color will follow SNAP color configuration on MAP -> SNAP settings preference.

Uikit Custom Settings

We provide Settings to handle more customizable UI in our SDK.

Skip Payment Status

Skip Payment Status

// Init custom settings
UIKitCustomSetting uisetting = new UIKitCustomSetting();
uisetting.setShowPaymentStatus(false); // hide sdk payment status
MidtransSDK.getInstance().setUIKitCustomSetting(uiKitCustomSetting);

UICONFIG.hideStatusPage = YES;

You can skip payment status provided by Midtrans SDK if you want to show your own status page.

Set Default save card options to true

Set default save card options to true

// Init custom settings
UIKitCustomSetting uisetting = new UIKitCustomSetting();
uiKitCustomSetting.setSaveCardChecked(true);
MidtransSDK.getInstance().setUIKitCustomSetting(uiKitCustomSetting);

CC_CONFIG.setDefaultCreditSaveCardEnabled = YES;

In credit card payment page, there is a checkbox to save card and it is not checked by default. You can make this checkbox checked by default by using this settings.

Skip customer detail

Skip customer detail

UIKitCustomSetting setting = MidtransSDK.getInstance().getUIKitCustomSetting();
uiKitCustomSetting.setSkipCustomerDetailsPages(true);
MidtransSDK.getInstance().setUIKitCustomSetting(setting);

On the first SDK usage, user are required to fill in customer details to make a payment. This setting is only for Android SDK due to the iOS SDK not having built-in customer details pages. You can skip this screen if you want by using UIKitCustomSetting.

Add customer contact in credit card form

Add customer contact in credit card form

UIKitCustomSetting setting = MidtransSDK.getInstance().getUIKitCustomSetting();
uiKitCustomSetting.setShowEmailInCcForm(true);
MidtransSDK.getInstance().setUIKitCustomSetting(setting);

If you want to show additional fields for customer contact (phone number and / or email), you can use this option. SDK will automatically display additional fields. Please note that both fields are optional.

To use this feature, please make sure you have installed our latest SDK.

Enable Auto Read OTP (Android Only)

Enable Auto Read SMS OTP

// Init custom settings
UIKitCustomSetting uisetting = new UIKitCustomSetting();
// enable auto read SMS
uiKitCustomSetting.setEnableAutoReadSms(true);
// set custom setting to SDK
MidtransSDK.getInstance().setUIKitCustomSetting(uiKitCustomSetting);

There is an option to enable auto read OTP for credit card payments. You can enable this option by using the following settings.

Bin Promo (Bin Filter)

Whitelist bin object will be like this:

"whitelist_bins": [
      "mandiri",
      "41111111"
    ]

Blacklist bin object will be like this:

"blacklist_bins": [
      "mandiri",
      "41111111"
    ]

So complete bin promo request will be like this:

{
    "transaction_details": {
        "order_id": "ORDER-ID",
        "gross_amount": 10000
    },
    "credit_card": {
        "secure": true,
        "whitelist_bins": [
            "bni",
            "459920"
        ],
          "blacklist_bins": [
            "bri",
            "410505"
          ]
    },
    "item_details": [
        {
            "id": "ITEM1",
            "price": 10000,
            "quantity": 1,
            "name": "Midtrans Bear"
        }
    ],
    "customer_details": {
        "first_name": "TEST",
        "last_name": "MIDTRANSER",
        "email": "test@midtrans.com",
        "phone": "+628123456",
        "billing_address": {
            "first_name": "TEST",
            "last_name": "MIDTRANSER",
            "email": "test@midtrans.com",
            "phone": "081 2233 44-55",
            "address": "Sudirman",
            "city": "Jakarta",
            "postal_code": "12190",
            "country_code": "IDN"
        },
        "shipping_address": {
            "first_name": "TEST",
            "last_name": "MIDTRANSER",
            "email": "test@midtrans.com",
            "phone": "0 8128-75 7-9338",
            "address": "Sudirman",
            "city": "Jakarta",
            "postal_code": "12190",
            "country_code": "IDN"
        }
    }
}

Credit card bins can be filtered by using whitelist_bins or blacklist_bins or both features. To use these features, merchant server must intercept mobile SDK’s request and add list of whitelist bin into request.

Note:

• This object needs to be added into credit_card object.
• If set of whitelisted bins intersects with set of blacklisted bins, then:
  1. Everything in whitelisted bins that is not mentioned in blacklisted bins will be accepted.
  2. Everything else will be denied

Parameter	Description
whitelist_bins Array (optional)	Allowed credit card BIN numbers. The bin value can be either a prefix (up to 8 digits) of card number or the name of a bank, in which case all the cards issued by that bank will be allowed. The supported bank names are bni bca mandiri cimb bri and maybank. Default: allow all cards
blacklist_bins Array (optional)	A list of credit card BIN numbers that cannot be used for the transaction. The bin value can be either a prefix (up to 8 digits) of card number or the name of a bank, in which case all the cards issued by that bank will be denied. The supported bank names are bni bca mandiri cimb bri and maybank. Default: allow all cards

Frequently Asked Questions

What is a merchant server?

Midtrans Mobile SDK requires merchant to have a server-side implementation to store SERVER_KEY and make charge request. As an implementation reference, please take a look at this wiki.

What is MERCHANT_BASE_URL?

It is the URL of your merchant server (backend).

Why did I get Mixpanel token error?

This error will not happen if you use the build that we have provided on bintray. If for some reason you don’t want to use the build that we have provided, you need to add your own mixpanel token by signing up to mixpanel first.

Why did I get this error “Access denied due to unauthorized transaction, please check client or server key”?

Please check whether you have used the correct client key and server key. The keys should also match the environment such that sandbox keys are used for sandbox environment, and production keys for production. If the keys are already correct but you still get the same error, make sure you have put the correct merchant server URL (MERCHANT_BASE_URL).

Why did I get response message “Token not found” when trying to do checkout?

Please make sure you have installed correct SDK and supplied corresponding credentials. In sandbox environment, please make sure that you use sandbox keys (client key and server key) and sandbox version of SDK (the name of SDK using postfix “-SANDBOX” eg: com.midtrans:uikit:1.16.0-SANDBOX).

Why did I get a blank screen when trying to do checkout?

First, please make sure you’ve already used our latest version of SDK (at least v1.15.3). If you still face this problem, please either do one of these two solutions : (1) supply user detail to SDK, or (2) use UIKitCustomSetting. Please refer to this guide on how to do one of them.

I got error when trying to do checkout.

First, please make sure you’ve already used our latest version of SDK. Then, please examine the error log captured in Logcat or other error reporting.

If the error looks like this :

E/AndroidRuntime: FATAL EXCEPTION: main java.lang.NoSuchMethodError: No virtual method load(Ljava/lang/Integer;)Lcom/bumptech/glide/DrawableTypeRequest; in class Lcom/bumptech/glide/RequestManager; or its super classes (declaration of ‘com.bumptech.glide.RequestManager’ appears in /data/app/id.packageaplikasi.app-1/base.apk:classes3.dex)

Then rest easy as this is a known problem. Our mobile SDK uses Glide v3.7 as image loader library, so if your app uses Glide too, make sure you use the same version (or at least v3.x) to avoid this error. We still work on it to make sure in the future, no such version clashing exist anymore.

Modify base theme to avoid error

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item> </style>

If the error looks like this :

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.yourcompany.appname/com.midtrans.sdk.uikit.activities.UserDetailsActivity}: java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.

You should have no worries. Since our mobile SDK uses Toolbar as ActionBar, you need to disable ActionBar in your app and use Toolbar instead. It requires you to modify your base theme.

For more information regarding this particular error, please refer to this Stack Overflow post.

I would like to test bank point. Is there any testing credential that I can use?

Sure. If you want to test bank point in sandbox environment, you can use this card number.

• BNI Point : 4105 0586 8948 1467
• Mandiri Fiestapoin : 4617 0069 5974 6656

The expiry and CCV are the same like any other testing cards. Please refer to this section to see other testing credential.

Why is the Gojek App can’t be opened from my app when using iOS SDK?

There is a case that Gojek app is not detected, while using our iOS SDK.

You will need to add LSApplicationQueriesSchemes key to your app’s Info.plist

Add LSApplicationQueriesSchemes key with this value:

<key>LSApplicationQueriesSchemes</key>
<array>
<string>gojek</string>
</array>

How to get pdf_url ?

pdf_url is an response property that provide url to download instruction of VA payment. Here’s how to get pdf_url : String pdfUrl = transactionResponse.getPdfUrl()

Handle Async Payment

There are some async payment supported by Midtrans:

• Internet Banking and Direct Debit
  • KlikBCA
  • BCA KlikPay
  • Epay BRI
  • CIMB Clicks
  • LINE Pay e-cash / mandiri e-cash
• Bank Transfer (Virtual Account)
  • BCA VA
  • Mandiri Bill
  • Permata VA
• Convenience Store
  • Indomaret
• Installment Method
  • Akulaku

If you’re using payment methods from above list, you will not get the latest transaction status after doing the charge using the SDK. SDK only returns the pending status when doing the charge to Midtrans Payment API.

Midtrans will update the transaction status after they receive notification from bank when the transaction is really completed.

There are two ways to know the latest transaction status:

• HTTP Notification sent from Midtrans backend
• Get Latest Transaction Status using Midtrans API

Handling HTTP Notification

In order to increase the security aspect, there are several ways to ensure that the notification received is from Midtrans.

Handle HTTP Notification (Using Veritrans PHP)

<?php

require_once('Veritrans.php');
Veritrans_Config::$isProduction = false;
Veritrans_Config::$serverKey = '<your serverkey>';
$notif = new Veritrans_Notification();

$transaction = $notif->transaction_status;
$type = $notif->payment_type;
$order_id = $notif->order_id;
$fraud = $notif->fraud_status;

if ($transaction == 'capture') {
  // For credit card transaction, we need to check whether transaction is challenge by FDS or not
  if ($type == 'credit_card'){
    if($fraud == 'challenge'){
      // TODO set payment status in merchant's database to 'Challenge by FDS'
      // TODO merchant should decide whether this transaction is authorized or not in MAP
      echo "Transaction order_id: " . $order_id ." is challenged by FDS";
      }
      else {
      // TODO set payment status in merchant's database to 'Success'
      echo "Transaction order_id: " . $order_id ." successfully captured using " . $type;
      }
    }
  }
else if ($transaction == 'settlement'){
  // TODO set payment status in merchant's database to 'Settlement'
  echo "Transaction order_id: " . $order_id ." successfully transfered using " . $type;
  }
  else if($transaction == 'pending'){
  // TODO set payment status in merchant's database to 'Pending'
  echo "Waiting customer to finish transaction order_id: " . $order_id . " using " . $type;
  }
  else if ($transaction == 'deny') {
  // TODO set payment status in merchant's database to 'Denied'
  echo "Payment using " . $type . " for transaction order_id: " . $order_id . " is denied.";
  }
  else if ($transaction == 'expire') {
  // TODO set payment status in merchant's database to 'expire'
  echo "Payment using " . $type . " for transaction order_id: " . $order_id . " is expired.";
  }
  else if ($transaction == 'cancel') {
  // TODO set payment status in merchant's database to 'Denied'
  echo "Payment using " . $type . " for transaction order_id: " . $order_id . " is canceled.";
}
?>

Challenge Response

An additional mechanism we provide to verify the content and the origin of the notification is to challenge. This can be achieved by calling the get status API. The response is the same as the notification status.

Signature Key

We added signature key information in our notification. The purpose of this signature key is to validate whether the notification is originated from Midtrans or not. Should the notification not be genuine, merchants can disregard the notification. Please find on the side, the logic of the signature key and the sample code to generate signature key.

Signature Key Logic

SHA512(order_id + status_code + gross_amount + serverkey)

Sample code generate signature key

<?php
$orderId = "1111";
$statusCode = "200";
$grossAmount = "100000.00";
$serverKey = "askvnoibnosifnboseofinbofinfgbiufglnbfg";
$input = $orderId.$statusCode.$grossAmount.$serverKey;
$signature = openssl_digest($input, 'sha512');
echo "INPUT: " , $input."<br/>";
echo "SIGNATURE: " , $signature;
?>

Best Practice to Handle notification

• Always use an HTTPS endpoint. It is secure and there cannot be MITM attacks because we validate the certificates match the hosts. Also do not use self signed certificates.
• Always implement notification in an idempotent way, in extremely rare cases, we may send multiple notifications for the same transaction event twice. It should not cause double entries on the merchant end. The simple way of achieving this is to use orderid as the key to track the entries.
• Always check the signature hash of the notification, This will confirm that the notification was actually sent by Midtrans, because we encode the shared secret (server key). Nobody else can build this signature hash.
• Always check all the following three fields to confirm successful transactions
  • status code: Should be 200 for successful transactions
  • fraud status: ACCEPT
  • transaction status : settlement/capture
• We strive to send the notification immediately after the transaction has occurred, but in extremely rare cases, it may be delayed because of transaction spikes. If you have not received a notification, please use the Status API to check the current status of the transaction.
• It is safe to call Status API to get the latest status of the transaction/order on each notification.
• We set the HTTP timeout to 30 seconds. Please strive to keep the response time of the HTTP notifications under 5 seconds.
• In extremely rare cases we may send the HTTP notifications out of order, ie. a settlement status for a notification before the notification for Pending status. It’s important that such later notifications are ignored. Here’s the state transition diagram that you could use. But again, use our /status API to confirm the actual status.
• We send the notification body as JSON, please parse the JSON with a JSON parser. Always expect new fields will be added to the notification body, so parse it in a non strict format, so if the parser sees new fields, it should not throw exception. It should gracefully ignore the new fields. This allows us to extend our notification system for newer use cases without breaking old clients.
• Always use the right HTTP Status code for responding to the notification, we handle retry for error cases differently based on the status code
  • for 2xx: No retries, it is considered success
  • for 500: We will retry 1 times in the 1 minute interval
  • for 503: Retry 4 times
  • for 400/404: retry 2 times in 1 minute interval
  • for all other failures: Retry 5 times at 1 minute interval
• Redirection
  • for 307/308: The request will be repeated with the new URL using POST method and the same notification body. A maximum of 5 redirection is allowed. -for 301/301/303: The job will be marked as failed without further retries. The merchant will be notified via email. We suggest either to use 307/308 or update the notification endpoint settings in merchant portal.

The following are the standard types of notifications. Note different types of notifications can be added in addition to the ones below. Also new fields may be added to the existing notification, please confirm with the latest documentation for the exact fields.

Get Transaction Status

Please refer to this docs.

GoPay Tokenization SDK

Overview

Gopay tokenization SDK allows your Android and iOS app users to link their Gopay account and perform payments within your app. Users can get their balance and choose which Gopay payment method they want to use. The SDK opens a secure webview for authorization. Other than that, you control the user experience.

Feature

Gopay tokenization SDK allows you to do the following:

1. Account linking - This feature links a user’s gopay account to your merchant ID.
2. Account status inquiry - This feature enquires about the status of a linked account. You’ll get the linking status, and if the account is linked, this feature will also provide the available Gopay payment options along with the balance and the token required to create transactions.
3. Create transactions - This feature creates transactions using the user’s token.
4. Disable account - This feature unlinks the account and disables the use of the user token.
5. API response processor - This feature simplifies the processing of use-cases that need further processing via Web in account linking and transaction API.

1. Account Linking

In order to be able to generate the token for transaction purposes, users need to link their wallet.

Account linking is the process for users to link their Gopay account to your merchant account. The result is a token used for:

• account status inquiry
• create a transaction
  
• disable an account

The overview of account linking is seen in this flow

To do account linking, you need to provide the GoPayPartnerDetails object that consisted of the following parameters:

Field	Explanation
PHONE_NUMBER	Phone number string without country code and without leading 0 with a minimum length of 9 characters maximum of 12 characters. Please refer to E.164 standard for this
COUNTRY_CODE	Country code string without the + sign with a minimum length of 1 character and a maximum of 3 characters. Please refer to the E.164 standard. For Indonesian merchants, please use 62 as the value

2. Account Status Enquiry

The account status inquiry is used before creating transactions. The API is required for the following purposes:

• Checking the account linking status
• Getting available payment options
• Getting the balance of each available payment option

Currently, we support Gopay Wallet and Gopay Paylater for account status, but this will be dynamically added or reduced. Please do not hardcode the types and rely on the resulting payment options.

The overview of the account status inquiry is seen in this flow.

The parameter that you need for this API is the account_id, which you get from the response from the account linking API.

The API will result in account information where you will get the linking status, list of available payment options. The payment options have the balance information and the payment option token that you need to create transactions.

3. Create Transaction

The overview for creating transactions is shown in this flow.

Created transactions are idempotent by nature. If you send the same transaction object, it will only check the same transaction on the server and return the same object without creating a new one.

The create transaction API is used to perform transactions from an already linked account. You need the following parameters to create transactions:

Field	Explanation
GoPayDetails	An object that contains account_id and payment_option_token from the account status inquiry process
TransactionDetails	An object that contains the gross_amount and currency
Items	This is a list of ItemDetail objects that specifies the items involved in the transaction. The information is item_id, name, price, quantity, and category. This is an optional parameter and can be set to null if not used

4. Disable Account

The API will stop the linking of user accounts from your merchant ID, and for making the payment option tokens unable to be used again. If the user needs to create transactions, the user account needs to be linked again.

The overview for disabling an account is shown in this flow.

The parameter that you need for this API is the account_id, which you get from the result of the account linking API.

Android SDK

Installation

Gopay Tokenization SDK is available via Gradle on Android. Add Midtrans Maven on build.gradle on the root project

// Android installation via gradle

iOS SDK

Installation

Gopay Tokenization SDK is available via Cocoapods on iOS.

Please follow the following steps to install the library to your app.

Step 1: Prepare the Podfile

Add the pod 'GopayCheckoutKit' to your Podfile

//Add the following to your Podfile
target 'MyApp' do
  pod 'GopayCheckoutKit'
end

Step 2: Execute the Podfile

On your terminal, run pod install

// do pod install in your terminal
$ pod install

Step 3: Add the code to the AppDelegate

• For Swift, you need to import GopayCheckoutKit in your AppDelegate.Swift File and every class where you plan to use the SDK method.

• For Objective-C, you need to import GopayCheckoutKit.h in your AppDelegate.h and every class where you plan to use the SDK method.

Step 4: Setup app URL scheme

This step is needed to let the SDK go back to close the webview automatically and navigate to the previous screen. For example, your app URL scheme should be something like myapp://, all lowercase.

To set up your app URL scheme, you can choose to either:

• Go to Project Settings -> Info, and add inside the URL Types section, a new URL scheme. Add something of the sort of myapp or any name you prefer, all lowercase.

• Alternatively, you can also go to your info.plist file and paste the following code. You can rename the myapp value with your preferred name.

Initialization

To start using the SDK, you need to initialize the installed libraries. You can provide the following mandatory parameters:

Parameter Name	Explanation
merchant_id	This is your merchant ID. You can find this in your Midtrans dashboard
callback_url	This is the callback URL that will redirect back after webview is invoked
merchant_server_url	This is the address of the merchant server that you register to Midtrans

In your AppDelegate file, you need to set up the SDK within the application:didFinishLaunchingWithOptions: and application:openURL:method.

Important Notes : For the callbackUrl parameter, please use your app URL scheme with this format myapp://app, by adding app to your app URL scheme, as shown in the code sample.

Note: Ever since iOS 13, Apple introduced SceneDelegate, So you’ll also need to add the handleCallbackUrl method of the sdk on the SceneDelegate file within the openURLContexts: method.

// setup your AppDelegate file

//init your sdk inside the didFinishLaunchingWithOptions: method
- (BOOL) application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

Checkout API Response Processor

For account linking and making payment API, some use-cases need further processing via Web. The checkout API response processor can be used to simplify it.

Since the response is processed beforehand, the app should already know the pending response. However, the processor does not know the actual status. So after completion, callback is called, the app should check the latest status API.

Merchant Server API Specification

There is a merchant server component in the transaction flow. The goal is to provide an extra layer of security since your Midtrans Server Key should be passed in the header of each request. The Server key is important, so you need to ensure that it is not embedded in your application since there’s a possibility of reverse engineering through decompilation. All requests coming from the SDK will not have the authorization header since the merchant server will provide this.

The server key that is base64 encoded should be in the Authorization request header. The rest of the headers and request body should just be forwarded. Once the response from the Partner API is received, the received request body, status code and request headers should be returned to the SDK.

The following sections define the specification of each required endpoints.

Account Linking

Endpoint address is /v2/pay/account Request method is POST Expected mandatory additional headers being sent to partner API are listed in the table below:

Field Name	Type	Value	Explanation
Content-Type	String	application/json	Standard requirement to define the incoming request content type.
Accept	String	application/json	Standard requirement to expect response content type.
Authorization	String	Base64 Encoded result of Server key	A string resulted from Base64 encoding of the Midtrans Merchant Server Key.

Partner API forwarding endpoint is /v2/pay/account Request Method is POST. Request Header should follow the above requirements. Request body should forward all request body sent from the SDK.

For every response from Partner API, please return to SDK and use the same request headers and request body. HTTP status code should follow the payload content in the status_code field.

Account Status Enquiry

Endpoint address is /v2/pay/account/<account id> Request method is GET The expected mandatory additional headers being sent to the partner API are listed in the table below:

Frequently Asked Questions

1. Do I need the Midtrans UIKit SDK to use the tokenization SDK?
   No, the Gopay tokenization SDK is a standalone SDK. It doesn’t have any dependency to the other Midtrans SDK.
2. Will there be any instances when my user needs to be redirected to the Gojek app in the middle of any of the payment flows?
   No, the SDK is designed to keep the user within your app. The authentication happens via a secure webview within your app.
3. Is it safe to store the payment option token on the backend or frontend or both?
   The token is safe to store. It can only be used to create transactions with your merchant ID, and it requires user’s authorization before it can be used.
4. What happens if the token is invalidated (by Midtrans/Gopay/user)?
   If the token is invalidated, the token can no longer be used to create transactions. If the user wants to do another transaction then the user needs to re-do the account linking flow.
5. Is there any information on the response object that is unsafe for storage or personally identifiable information?
   No, all information provided is safe to store.
6. Is Paylater supported?
   Paylater is one of the options available in the payment options list if your user is eligible to use it.
7. How do I differentiate between sandbox and production environments?
   You can do that by switching the merchant server URL between sandbox and production in your own server environment.
8. How can I ensure that users can’t do credit based payments?
   You will get the available payment option when you enquire about the account status. Do not show the PayLater options from the list as a payment option.
9. When will the PIN request webview pop up?
   The PIN request webview will pop up during the following conditions. Account linking process after user enters the OTP and during transaction creation to authorize the payment
10. Do I need to give my users the options to “unlink/disable their accounts”?
    You need to give users the control over the use of their payment tokens. Be explicit on what happens after a user unlinked/disabled the account.
11. Do I have to notify my users when a transaction takes place using a token?
    Users will know that they entered the authorization PIN and afterward will expect a status on the payment. We will notify your merchant server via HTTP notification and you can notify the users on the payment status change after the success notification was received.
