Introduction

Stripe webhooks are an essential feature for handling real-time payment events, such as successful payments, subscription changes, payment failures, and other relevant updates. By integrating Stripe webhooks into your Spring Boot application, you can efficiently track and respond to payment events. This guide demonstrates how to handle these events by setting up a webhook endpoint and processing the incoming events in a Spring Boot application.

Setting Up Stripe Webhooks in Spring Boot

To get started, you need to set up the webhook listener in your Spring Boot application. First, ensure you have your Stripe dependency in pom.xml:

Next, create a webhook handler class that listens to events from Stripe and processes them accordingly.

Implementing Stripe Webhook Handler in Spring Boot

Step 1: Configure Webhook Endpoint

Stripe will send HTTP POST requests to a webhook URL whenever a relevant event occurs, such as a successful payment, failed transaction, or subscription update. You need to create a @PostMapping method in a controller to receive these events.

Step 2: Webhook Security

Stripe requires you to validate the authenticity of the webhook events to prevent potential malicious requests. This is done using the Stripe-Signature header and the endpoint secret key.

• endpointSecret is retrieved from the Stripe Dashboard and is used to verify that the event is indeed sent from Stripe.
• Webhook.constructEvent() is a utility method that checks the signature and validates the event.

Step 3: Handle Specific Payment Events

Stripe sends a wide variety of events depending on the actions taken within the Stripe ecosystem, such as payment success, subscription cancellation, payment failures, etc. The Event object includes an event type (event.getType()) that helps identify the kind of event and decide how to process it.

Common Stripe event types include:

• payment_intent.succeeded – When a payment is successful.
• payment_intent.failed – When a payment fails.
• invoice.payment_succeeded – When an invoice payment succeeds.
• invoice.payment_failed – When an invoice payment fails.

In the example above, the event type is checked, and corresponding methods like handlePaymentIntentSucceeded() or handleInvoicePaymentFailed() are called to process the specific event.

Step 4: Processing the Event Data

Each event contains useful data, such as the payment amount, customer details, and payment method. You can access this data via the Event object.

For instance, in the handlePaymentIntentSucceeded() method, the event contains a PaymentIntent object that includes information about the successful payment:

Practical Example of Webhook Handling

Example 1: Updating Order Status After Payment Success

When a payment_intent.succeeded event is received, you may want to update the order status in your database to reflect that the payment was successfully processed.

Conclusion

Handling Stripe payment events with webhooks in Spring Boot is a powerful way to keep your application in sync with Stripe’s payment system. By setting up a webhook endpoint, verifying event authenticity, and processing various event types like payment_intent.succeeded and invoice.payment_failed, you can effectively manage real-time payment updates. This integration ensures that your application can respond quickly to changes in payment status, providing a seamless experience for your users.
