+
+In this document, you’ll learn how the Payment Module supports listening to webhook events.
+
+## What's a Webhook Event?
+
+A webhook event is sent from a third-party payment provider to your application. It indicates a change in a payment’s status. This is useful in different cases such as when a payment is being processed asynchronously or when a request is interrupted.
+
+---
+
+## processEvent Method
+
+The Payment Module’s main service (`IPaymentModuleService`) provides a `processEvent` method used to handle incoming webhook events from third-party providers. The method delegates the handling to the associated payment provider, which returns the event's details.
+
+If the event's details indicate that the payment should be authorized, then the `authorizePaymentSession` of the main service is executed on the specified payment session.
+
+If the event's details indicate that the payment should be captured, then the `capturePayment` of the main service is executed on the payment of the specified payment session.

+
+You can use this method in your webhook listener API routes or endpoints.
+
+<Note>
+
+Medusa V2 implements a webhook listener at the `/hooks/payment/[provider]` API route, where `[provider]` is the ID of the provider (for example, `stripe`). You can use that webhook listener in your third-party payment provider's configurations.
+
+</Note>
+
+For example:
+
+```ts
+await paymentModuleService.processEvent({
+  provider: "stripe",
+  payload: {
+    // webhook event data
+  },
+})
+```
