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

    "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";

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';

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);

CancelTransactionRequest *cancelTransactionRequest = [[CancelTransactionRequest alloc] initWithPaymentToken: paymentToken];

let cancelTransactionRequest: CancelTransactionRequest = CancelTransactionRequest(paymentToken: paymentToken)

Map<String, dynamic> cancelTransactionRequest = {
   'paymentToken': paymentToken
};

 

4. Retrieve Cancel Transaction Response

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

Response API Parameters

Refer to: Cancel Transaction Response API Parameters

PGWSDK.getInstance().cancelTransaction(cancelTransactionRequest, new APIResponseCallback<CancelTransactionResponse>() {
 
     @Override
     public void onResponse(CancelTransactionResponse response) {
         if(response.getResponseCode().equals(APIResponseCode.APISuccess)) {
             //Read cancel transaction response. 
         } else {
             //Get error response and display error.
         }
     }
 
     @Override
     public void onFailure(Throwable error) {
         //Get error response and display error.
     }
});

[[PGWSDK shared] cancelTransactionWithCancelTransactionRequest: cancelTransactionRequest response: ^(CancelTransactionResponse * _Nonnull response) {
         
     if([response.responseCode isEqualToString: APIResponseCode.APISuccess]) {
          //Read cancel transaction response.
     } else { 
         //Get error response and display error.
     }
} failure: ^(NSError * _Nonnull error) { 
     //Get error response and display error.
}];

PGWSDK.shared.cancelTransaction(cancelTransactionRequest: cancelTransactionRequest, { (response: CancelTransactionResponse) in
 
     if response.responseCode == APIResponseCode.APISuccess {
          //Read cancel transaction response.
     } else {
          //Get error response and display error.
     }
}) { (error: NSError) in 
     //Get error response and display error.
}

PGWSDK().cancelTransaction(cancelTransactionRequest, (response) {
 
   if (response['responseCode'] == APIResponseCode.apiSuccess) {
 
      //Read cancel transaction response.
   } else {
 
      //Get error response and display error.
   }
}, (error) {
 
   //Get error response and display error.
});
