Prerequisite
Refer all the steps and images from following link.
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": "JT01",
"invoiceNo": "1595219400",
"description": "2 days 1 night hotel room",
"amount": 10.0,
"currencyCode": "SGD",
"nonceStr": "a8092512-b144-41b0-8284-568bb5e9264c",
"paymentChannel": ["DPAY"],
"request3DS": "Y"
}
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";
String paymentToken = 'roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL';
3. Retrieve Payment Provider Info from Payment Option Details API.
To receive a payment provider info, refer to the sample payment option detail response below.
PaymentChannel paymentChannel = paymentOptionDetailResponse.getChannels().stream().filter((channel) -> channel.getContext().getCode().getChannelCode().equalsIgnoreCase("GOOGLEPAY")).findAny().orElse(null);
PaymentProvider paymentProvider = paymentChannel != null ? paymentChannel.getContext().getInfo().getPaymentProvider() : null;
Map<String, dynamic>? paymentProvider = paymentOptionDetailResponse['channels'].firstWhere((f) => f['context']?['code']?['channelCode'] == PaymentChannelCode.channel.googlePay, orElse: () => null)?['context']?['info']?['paymentProvider'];
Payment Option Detail Parameter
4. Construct Google Pay Token Request
PaymentProviderRequest paymentProviderRequest = new PaymentProviderBuilder(getActivity())
.setPaymentProvider(paymentProvider)
.build();
PGWSDKHelper.getInstance().proceedGooglePayPayment(paymentProviderRequest, new PaymentResultResponseCallback<GooglePayPaymentResultResponse>() {
@Override
public void onResponse(GooglePayPaymentResultResponse response) {
if(response.getResponseCode().equalsIgnoreCase(GooglePayPaymentResponseCode.TokenGeneratedSuccess)) {
} else {
//Get error response and display error.
}
}
@Override
public void onFailure(Throwable error) {
//Get error response and display error.
}
});
PGWSDKHelper().proceedGooglePayPayment(paymentProvider!, null, GooglePayAPIEnvironment.test, (response) {
if (response['responseCode'] == GooglePayPaymentResponseCode.tokenGeneratedSuccess) {
} else {
//Get error response and display error
}
}, (error) {
//Get error response and display error
});
5. Construct Google Pay Payment Request
To prepare an e-wallet payment request, refer to the sample code below.
Payment Request Parameters
Refer to Payment Request API Parameters
Payment Channel Matrix
Refer to the payment channel codes for the Google Pay e-wallet below.
| Category Code | Group Code | Channel | Name | Country |
|---|---|---|---|---|
| DPAY | CWALLET | GOOGLEPAY | Google Pay | Global |
PaymentCode paymentCode = new PaymentCode("GOOGLEPAY");
PaymentRequest paymentRequest = new DigitalPaymentBuilder(paymentCode)
.setName("DavidBilly")
.setEmail("[email protected]")
.setToken(response.getToken())
.build();
Map<String, dynamic> paymentCode = {
'channelCode': 'GOOGLEPAY'
};
Map<String, dynamic> paymentRequest = {
'name': 'DavidBilly',
'email': '[email protected]',
'token': response['token']
};
6. Construct 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();
Map<String, dynamic> transactionResultRequest = {
'paymentToken': paymentToken,
'payment': {
'code': {
...paymentCode
},
'data': {
...paymentRequest
}
}
};
7. Execute Payment Request
To receive a transaction request response, refer to the parameters below.
Transaction Response API Parameter
Refer to: Do Payment Response API Parameters
References
Response Code
To view payment process flows based on response code, refer to: Payment Flow Response Codes
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.TransactionCompleted)) {
//Inquiry payment result by using invoice no.
} else {
//Get error response and display error
}
}
@Override
public void onFailure(Throwable error) {
//Get error response and display error
}
});
PGWSDK().proceedTransaction(transactionResultRequest, (response) {
if (response['responseCode'] == APIResponseCode.transactionCompleted) {
//Inquiry payment result by using invoice no.
} else {
//Get error response and display error.
}
}, (error) {
//Get error response and display error.
});
Callback for PGW Payment Authentication
Refer to: Handle PGW Payment Authentication
