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

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";
val 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"
String paymentToken = 'roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL';
let paymentToken = 'roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL';

3. Prepare Cancel Transaction Request

To prepare a cancel transaction request, refer to the parameters below.

📘

Request API Parameters

Refer to: Cancel Transaction Request API Parameters

CancelTransactionRequest cancelTransactionRequest = new CancelTransactionRequest(paymentToken);
val cancelTransactionRequest = CancelTransactionRequest(paymentToken)
CancelTransactionRequest *cancelTransactionRequest = [[CancelTransactionRequest alloc] initWithPaymentToken: paymentToken];
let cancelTransactionRequest: CancelTransactionRequest = CancelTransactionRequest(paymentToken: paymentToken)
Map<String, dynamic> cancelTransactionRequest = {
   'paymentToken': paymentToken
};
let cancelTransactionRequest = {
    'paymentToken': paymentToken
};

4. Retrieve Cancel Transaction Response

To retrieve a cancel transaction response, refer to the parameters below.
