Samples

The following samples show how to call the PaymentService SPI to initiate the payment process and handle the payment result.

Create a class that implements the PaymentService interface.
Within this class, implement the pay method to initiate the payment process and request for payment with the type of order, and handle the payment result.

Java

copy
public class PaymentServiceImpl implements PaymentService  {
    @Override
    public void pay(PaymentRequest paymentRequest, APIContext apiContext, Callback<PaymentResult> callback) {
        // to payment code
        callback.result(new PaymentResult(resultCode, resultMessage));

}

Kotlin

copy
class PaymentServiceImpl : PaymentService {
    override fun pay(paymentRequest: PaymentRequest?, apiContext: APIContext?, callback: Callback<PaymentResult>?) {
        // to payment code
        callback?.result(PaymentResult(resultCode,resultMessage))
    }
}
