Step 1 :Generate Payment Token

 
1.1 Generate payment token ID.

📘

Payment Token API

Please refer: Payment Token API

{
    "merchantID": "JT04",
    "invoiceNo": "1595219400",
    "description": "2 days 1 night hotel room",
    "amount": 10.0,
    "currencyCode": "THB",
    "nonceStr": "a8092512-b144-41b0-8284-568bb5e9264c",
    "paymentChannel": ["GBNPL"]
}

 
1.2 Get payment token ID from response and pass it to merchant mobile application.

String paymentToken = "roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL";
NSString *paymentToken = @"roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL";
let paymentToken: String = "roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL"

 

Step 2 : Construct Payment Request

Below code show how to construct payment request.

📘

Payment Request Parameter

Please refer: Buy Now Pay Later Payment Request API Parameter

🚧

Payment Channel

Buy Now Pay Later payment support a few of options.
Please refer Payment Channel Matrix to know the Channel for individual BNPL payment option.

PaymentCode paymentCode = new PaymentCode("HOOLAH");
 
PaymentRequest paymentRequest = new BuyNowPayLaterPaymentBuilder(paymentCode)
                                .setName("DavidBilly")
                                .setEmail("[email protected]")
                                .build();
PaymentCode *paymentCode = [[PaymentCode alloc] initWithChannelCode: @"HOOLAH"];
     
PaymentRequest *paymentRequest = [[[[[BuyNowPayLaterPaymentBuilder alloc] initWithPaymentCode: paymentCode]
                                      name: @"DavidBilly"]
                                      email: @"[email protected]"]
                                      build];
let paymentCode: PaymentCode = PaymentCode(channelCode: "HOOLAH")
 
let paymentRequest: PaymentRequest = BuyNowPayLaterPaymentBuilder(paymentCode: paymentCode)
                                     .name("DavidBilly")
                                     .email("[email protected]")
                                     .build()

 

Step 3 : Construct Transaction Request

Below code show how to construct transaction request.

📘

Transaction Request API Parameter

Please refer: Do Payment Request API Parameter

TransactionResultRequest transactionResultRequest = new TransactionResultRequestBuilder(paymentToken)
                                                    .with(paymentRequest)
                                                    .build();
TransactionResultRequest *transactionResultRequest = [[[[TransactionResultRequestBuilder alloc] initWithPaymentToken: paymentToken]
                                                         withPaymentRequest: paymentRequest]
                                                         build];
let transactionResultRequest: TransactionResultRequest = TransactionResultRequestBuilder(paymentToken: paymentToken)
                                                         .with(paymentRequest)
                                                         .build()

 

Step 4 : Execute Payment Request
