JarCastingConnect2Pay Payment Page Java Client
This is the Java implementation of the Connect2pay Payment Page API.
The main class to use is Connect2payClient that implements all the API calls.
It requires request object as entries and returns response objects.
Example of a payment creation with user redirection:
import com.payxpert.connect2pay.client.containers.Account;
import com.payxpert.connect2pay.client.containers.Order;
import com.payxpert.connect2pay.client.containers.Shipping;
import com.payxpert.connect2pay.client.containers.Shopper;
import com.payxpert.connect2pay.client.requests.PaymentRequest;
import com.payxpert.connect2pay.constants.PaymentMode;
import com.payxpert.connect2pay.constants.sca.ShippingType;
import com.payxpert.connect2pay.constants.sca.ShopperAccountAge;
import com.payxpert.connect2pay.constants.sca.ShopperAccountLastChange;
class TestPayment {
public void processPayment() {
// Process a payment of €39.99
PaymentRequest request = new PaymentRequest();
request.setCurrency("EUR").setAmount(3999);
request.setPaymentMode(PaymentMode.SINGLE);
// User will be redirected here when clicking on "Go back to merchant" button
request.setCtrlRedirectURL("http://my.website/somewhere");
// The payment page will do a callback on this URL after the payment is processed
request.setCtrlCallbackURL("http://my.website/payment-callback");
Order order = new Order();
order.setId("1234ABCD").setShippingType(ShippingType.DIGITAL_GOODS);
Shopper shopper = new Shopper();
shopper.setEmail("[email protected]").setFirstName("John").setLastName("Doe")
.setHomePhonePrefix("47").setHomePhone("123456789").setAddress1("Main Street 41")
.setZipcode("123456").setCity("London").setCountryCode("GB");
Account account = new Account();
account.setAge(ShopperAccountAge.BETWEEN_30_60_DAYS).setSuspicious(false)
.setLastChange(ShopperAccountLastChange.BETWEEN_30_60_DAYS);
shopper.setAccount(account);
Shipping shipping = new Shipping();
shipping.setName("Jane Doe").setAddress1("Other Street, 54").setCity("London")
.setZipcode("654321").setCountryCode("GB");
request.setOrder(order);
request.setShopper(shopper);
request.setShipping(shipping);
// Validate the request
try {
request.validate();
} catch (BadRequestException e) {
logger.error("Ooops, an error occurred validating the payment request: " + e.getMessage());
// Handle the error...
}
// Instantiate the client and send the prepare request
// Second argument is the originator ID, third one is the associated API key
Connect2payClient c2p = new Connect2payClient("https://provided.url", "123456", "GreatP4ssw0rd");
PaymentResponse response = null;
try {
response = c2p.preparePayment(request);
} catch (Exception e) {
logger.error("Ooops, an error occurred preparing the payment: " + e.getMessage());
// Handle the error...
}
if (response != null && ResultCode.SUCCESS.equals(response.getCode())) {
// Get the URL to redirect the user to
String redirectURL = response.getCustomerRedirectURL();
if (redirectURL != null) {
// Redirect the user towards this URL, this will display the payment page
}
} else {
// Handle the failure
}
}
}
Example of the payment callback handling:
import java.io.OutputStream;
class TestPayment {
private OutputStream out;
public void handleCallback(String request) {
// Instantiate the client and handle the callback
Connect2payClient c2p = new Connect2payClient("https://provided.url", "123456", "GreatP4ssw0rd");
PaymentStatusResponse response = null;
try {
// Request is either the body of the received request as a string or an InputStream pointing to the received body
response = c2p.handleCallbackStatus(request);
} catch (Exception e) {
logger.error("Ooops, an error occurred handling the callback: " + e.getMessage());
// Handle the error...
}
if (response != null && ResultCode.SUCCESS.equals(response.getCode())) {
// Check the payment status: 000 means success
if ("000".equals(response.getErrorCode())) {
// Handle the payment success case
// ...
// Access the payment mean information
CreditCardPaymentMeanInfo pmInfo = response.getCCPaymentMeanInfo();
logger.info("Successful payment done by " + pmInfo.getCardHolderName() + "with card " + pmInfo.getCardNumber());
} else {
// Handle the payment failure case
}
if (handledSuccessfully) {
this.out.write(CallbackStatusResponse.getDefaultSuccessResponse().toJson()); // out is the output stream
} else {
this.out.write(CallbackStatusResponse.getDefaultFailureResponse().toJson()); // out is the output stream
}
} else {
// Handle the failure
this.out.write(CallbackStatusResponse.getDefaultFailureResponse().toJson()); // out is the output stream
}
}
}
