API Method
References
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"]
}
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.
NSString *paymentToken = @"roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL";
let paymentToken: String = "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.
NSArray<PaymentChannel *> *filteredPaymentChannels = [[paymentOptionDetailResponse.channels mutableCopy] filteredArrayUsingPredicate: [NSPredicate predicateWithBlock: ^BOOL(PaymentChannel *paymentChannel, NSDictionary *bindings) {
return [paymentChannel.context.code.channelCode caseInsensitiveCompare: @"APPLEPAY"] == NSOrderedSame;
}]];
PaymentProvider *paymentProvider = filteredPaymentChannels.count > 0 ? filteredPaymentChannels[0].context.info.paymentProvider : nil;
let paymentProvider: PaymentProvider? = paymentOptionDetailResponse.channels.filter({ $0.context.code.channelCode == "APPLEPAY" }).first?.context.info.paymentProvider
Payment Option Detail Parameter
4. Construct Apple Pay Token Request
PaymentProviderRequest *paymentProviderRequest = [[[[PaymentProviderBuilder alloc] init]
paymentProvider: paymentProvider]
build];
[[PGWSDKHelper shared] proceedApplePayPaymentWithPaymentProviderRequest: paymentProviderRequest response: ^(ApplePayPaymentResultResponse * _Nonnull response) {
if([response.responseCode isEqualToString: ApplePayPaymentResponseCode.TokenGeneratedSuccess]) {
} else {
//Get error response and display error.
}
} failure: ^(NSError * _Nonnull error) {
//Get error response and display error.
}];
let paymentProviderRequest: PaymentProviderRequest = PaymentProviderBuilder()
.paymentProvider(paymentProvider!)
.build()
PGWSDKHelper.shared.proceedApplePayPayment(paymentProviderRequest: paymentProviderRequest, { (response: ApplePayPaymentResultResponse) in
if response.responseCode == ApplePayPaymentResponseCode.TokenGeneratedSuccess {
} else {
//Get error response and display error
}
}) { (error: NSError) in
//Get error response and display error
}
5. Construct Apple 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 Apple Pay e-wallet below.
| Category Code | Group Code | Channel | Name | Country |
|---|---|---|---|---|
| DPAY | CWALLET | APPLEPAY | Apple Pay | Global |
PaymentCode *paymentCode = [[PaymentCode alloc] initWithChannelCode: @"APPLEPAY"];
PaymentRequest *paymentRequest = [[[[[[DigitalPaymentBuilder alloc] initWithPaymentCode: paymentCode]
name: @"DavidBilly"]
email: @"[email protected]"]
token: response.token]
build];
let paymentCode: PaymentCode = PaymentCode(channelCode: "APPLEPAY")
let paymentRequest: PaymentRequest = DigitalPaymentBuilder(paymentCode: paymentCode)
.name("DavidBilly")
.email("[email protected]")
.token(response.token)
.build()
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 = [[[[TransactionResultRequestBuilder alloc] initWithPaymentToken: paymentToken]
withPaymentRequest: paymentRequest]
build];
let transactionResultRequest: TransactionResultRequest = TransactionResultRequestBuilder(paymentToken: paymentToken)
.with(paymentRequest)
.build()
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 shared] proceedTransactionWithTransactionResultRequest: transactionResultRequest response: ^(TransactionResultResponse * _Nonnull response) {
if([response.responseCode isEqualToString: APIResponseCode.TransactionCompleted]) {
//Inquiry payment result by using invoice no.
} 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.TransactionCompleted {
//Inquiry payment result by using invoice no.
} else {
//Get error response and display error
}
}) { (error: NSError) in
//Get error response and display error
}
Callback for PGW Payment Authentication
