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": ["DPAY"]
}

 
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"

                                .build();
PaymentCode *paymentCode = [[PaymentCode alloc] initWithChannelCode: @"MOMO"];
          
PaymentRequest *paymentRequest = [[[[[[DigitalPaymentBuilder alloc] initWithPaymentCode: paymentCode]
                                       name: @"DavidBilly"]
                                       email: @"[email protected]"]
                                       accountNo: @"0070000001"]
                                       build];
let paymentCode: PaymentCode = PaymentCode(channelCode: "MOMO")
 
let paymentRequest: PaymentRequest = DigitalPaymentBuilder(paymentCode: paymentCode)
                                     .name("DavidBilly")
                                     .email("[email protected]")
                                     .accountNo("0070000001")
                                     .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.

Below code show how to execute payment request and receive API response code.

📘

Transaction Response API Parameter

Response Code
Please refer : Payment Flow Response Code for payment process flow by response code.

PGWSDK.getInstance().proceedTransaction(transactionResultRequest, new APIResponseCallback<TransactionResultResponse>() {
    
     @Override
     public void onResponse(TransactionResultResponse response) {
    
          if(response.getResponseCode().equals(APIResponseCode.TransactionAuthenticateRedirect) || response.getResponseCode().equals(APIResponseCode.TransactionAuthenticateFullRedirect)) {
    
                String redirectUrl = response.getData(); //Open WebView
          } else if(response.getResponseCode().equals(APIResponseCode.TransactionExternalApplication)) {
    
               String appDeepLink = response.getData(); //Open app
          } else {
    
               //Get error response and display error.
          }
     }
    
     @Override
     public void onFailure(Throwable error) {
    
          //Get error response and display error.
     }
});
[[PGWSDK shared] proceedTransactionWithTransactionResultRequest: transactionResultRequest response: ^(TransactionResultResponse * _Nonnull response) {
              
     if([response.responseCode isEqualToString: APIResponseCode.TransactionAuthenticateRedirect] || [response.responseCode isEqualToString: APIResponseCode.TransactionAuthenticateFullRedirect]) {
                  
          NSString *redirectUrl = response.data; //Open WebView
     } else if([response.responseCode isEqualToString: APIResponseCode.TransactionExternalApplication]) {
                  
          NSString *appDeepLink = response.data; //Open app
     } else {
                  
          //Get error response and display error.
     }
} failure: ^(NSError * _Nonnull error) {
              
     //Get error response and display error.
}];
PGWSDK.shared.proceedTransaction(transactionResultRequest: transactionResultRequest, { (response: TransactionResultResponse) in
      
     if response.responseCode == APIResponseCode.TransactionAuthenticateRedirect || response.responseCode == APIResponseCode.TransactionAuthenticateFullRedirect {
                   
           guard let redirectUrl: String = response.data else { return } //Open WebView
     } else if response.responseCode == APIResponseCode.TransactionExternalApplication {
                
           guard let appDeepLink: String = response.data else { return } //Open app
     } else {
                   
           //Get error response and display error.
     }
}) { (error: NSError) in
               
     //Get error response and display error.
}

 
Step 5: Initiate Payment Inquiry.

Retrieve payment detail, required initiate Payment Inquiry API from merchant server end.
