1. Generate Payment Token

To prepare a payment token request, refer to the required parameters below.

📘

Payment Token API

Refer to: Payment Token API

{
    "merchantID": "JT04",
    "invoiceNo": "1595219400",
    "description": "2 days 1 night hotel room",
    "amount": 10.0,

    "nonceStr": "a8092512-b144-41b0-8284-568bb5e9264c",
    "paymentChannel": ["GBNPL"]
}

 

2. Receive Payment Token Response

To receive a payment token response, refer to the sample payment token response below. The response will contain the payment token ID which must be passed to the merchant 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"

 

3. Prepare Payment Request

To prepare a payment request, refer to the sample code below.

📘

Payment Request Parameters

Refer to: Buy Now Pay Later Payment Request API Parameter

🚧

Payment Channels

To see supported channels for individual BNPL options, refer to:Payment Channel Matrix

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()

 

4. Prepare Transaction Request

To prepare a transaction request, refer to the parameters and sample code below.

📘

Transaction Request API Parameters

Refer to: Do Payment Request API Parameters

TransactionResultRequest transactionResultRequest = new TransactionResultRequestBuilder(paymentToken)
                                                    .with(paymentRequest)
                                                    .build();
