stripe-webhook-validation

Stripe webhook signature validation fails when the Express or NestJS body parser modifies the payload before verification. You must pass the raw request body to stripe.webhooks.constructEvent to correctly verify signatures and prevent 400 errors.

To configure raw body parsing for Stripe webhooks in Express, use the express.raw middleware specifically for your webhook endpoint. This ensures the original request body is preserved for stripe.webhooks.constructEvent signature verification.

Yes, this Stripe webhook validation pattern supports NestJS. It provides specific implementation patterns to safely capture the raw request body in NestJS, ensuring correct signature verification and secure error handling for missed events.

The best way to handle Stripe webhook signature mismatch errors is to implement graceful error handling with helpful logging. This approach diagnoses signature verification failures securely without exposing sensitive endpoint details to the client.

No, you do not need to disable body parsing globally to verify Stripe webhook signatures. You can selectively apply raw body parsing middleware to the specific webhook endpoint in Express or NestJS while keeping JSON parsing for other routes.
