1. Generate Payment Token

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

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

3. Prepare Exchange Rate Request

To prepare an exchange rate request, refer to the parameters below.

📘

Request API Parameters

Refer to: Exchange Rate Request API Parameters

ExchangeRateRequest exchangeRateRequest = new ExchangeRateRequest(paymentToken);
exchangeRateRequest.setBin("411111");
ExchangeRateRequest *exchangeRateRequest = [[ExchangeRateRequest alloc] initWithPaymentToken: paymentToken];
exchangeRateRequest.bin = @"41111";
let exchangeRateRequest: ExchangeRateRequest = ExchangeRateRequest(paymentToken: paymentToken)
exchangeRateRequest.bin = "411111"

 

4. Retrieve Exchange Rate Response

To retrieve an exchange rate response, refer to the parameters below.

📘

Response API Parameters

Refer to: Exchange Rate Response API Parameters

PGWSDK.getInstance().exchangeRate(exchangeRateRequest, new APIResponseCallback<ExchangeRateResponse>() {
     @Override
     public void onResponse(ExchangeRateResponse response) {
         if(response.getResponseCode().equals(APIResponseCode.APISuccess)) {
             //Read exchange rate response. 
         } else {
             //Get error response and display error.
         }
     }
 
     @Override
     public void onFailure(Throwable error) {
         //Get error response and display error.
     }
});
[[PGWSDK shared] exchangeRateWithExchangeRateRequest: exchangeRateRequest response: ^(ExchangeRateResponse * _Nonnull response) {       
     if([response.responseCode isEqualToString: APIResponseCode.APISuccess]) {
          //Read exchange rate response.
     } else {
         //Get error response and display error.
     }
} failure: ^(NSError * _Nonnull error) { 
     //Get error response and display error.
}];
PGWSDK.shared.exchangeRate(exchangeRateRequest: exchangeRateRequest, { (response: ExchangeRateResponse) in
     if response.responseCode == APIResponseCode.APISuccess {
          //Read exchange rate response.
     } else {
          //Get error response and display error.
     }
}) { (error: NSError) in
     //Get error response and display error.
}
