How To Integrate Adyen Into Your App from the Backend Perspective?

Adyen integration into an application's backend involves several crucial steps to ensure secure and efficient payment processing. This part outlines the process, focusing on Java-based Adyen integration.

Initial Setup and Configuration

Before diving into the coding part, it's essential to set up an account with Adyen and get the necessary Adyen API integration keys. These keys will authenticate requests made from the application to Adyen's servers. After obtaining these keys, store them securely, as they are crucial for the interaction between the app and Adyen.

Maven Dependency

For Java applications, integrating Adyen starts with adding the required dependency to the project’s build file. For Maven projects, include the following in the pom.xml:

< dependency>
    < groupId>com.adyen</groupId>

Replace {adyen.api.version} with the latest version of the Adyen API library.

Establishing a Client

For Adyen API integration you need to create an instance of Client which is essential for making API calls. This requires the API key obtained during the initial setup.

import com.adyen.Client;
import com.adyen.enums.Environment;

public class AdyenClient {
    private static final String API_KEY = "YOUR_API_KEY";

    public Client initializeClient() {
        Client client = new Client(API_KEY, Environment.TEST);
        return client;

Creating a Payment Session

The next step of Adyen classic integration involves creating a payment session. Here, a PaymentRequest object is prepared and sent to Adyen's servers.

import com.adyen.model.checkout.PaymentRequest;
import com.adyen.service.Checkout;

public class PaymentService {

    public PaymentRequest createPaymentRequest() {
        PaymentRequest paymentRequest = new PaymentRequest();
        // Set the currency and value
        paymentRequest.setAmount(new Amount().currency("EUR").value(1000));
        // Unique order reference
        // URL to return to after payment completion
        // Additional configurations can be added here

        return paymentRequest;

    public String initiatePayment(Client client, PaymentRequest paymentRequest) throws Exception {
        Checkout checkout = new Checkout(client);
        return checkout.payments(paymentRequest).getPaymentData();

Processing the Payment

Once the payment request is sent, the application needs to handle the response, which includes the payment result.

public class PaymentResponseHandler {

    public void handlePaymentResponse(PaymentResult paymentResult) {
        if ("Authorised".equals(paymentResult.getResultCode())) {
            // Handle authorised payment
        } else {
            // Handle other payment outcomes such as Refused, Cancelled, etc.

Handling Webhooks

Adyen sends notifications about events such as payment authorizations, captures, or cancellations through webhooks. Setting up a listener endpoint to receive these notifications is important for keeping the payment status updated.

public class WebhookHandler {

    public void handleNotification(NotificationRequest notificationRequest) {
        for (NotificationRequestItem item : notificationRequest.getNotificationItems()) {
            // Process the notification item

Best Practices and Security

Ensure that sensitive information like API keys is stored securely and not hard-coded.

Regularly update the Adyen library to incorporate the latest security patches and features.

Be compliant with PCI DSS standards if handling or storing card details.

Going Live

After successful testing, switch to Adyen's live environment by updating the API keys and endpoints. Perform final validation to ensure everything works as expected in the live environment.

Adyen payment gateway integration examples can be found in the documentation, showcasing how to implement the solution in various programming languages. For example, Adyen Salesforce integration enables seamless synchronization of payment data with CRM systems, enhancing customer relationship management.


To conclude, integrating Adyen for payment processing in an application involves a few key steps: setting up Adyen, adding the Java library, establishing a client connection, creating payment requests, processing responses, and handling notifications through webhooks. Following these steps allows for efficient and secure payment transactions directly within the app, enhancing the user experience. It's important to keep the system updated and maintain strong security practices for reliable and effective payment integration.
