To build a secure webhook receiver, implement HMAC-SHA256 signature verification to validate request legitimacy, parse the payment payload, and use idempotency handling to prevent processing duplicate Stripe events during delivery retries.

Webhook idempotency prevents duplicate processing of the same event when external services retry delivery. It is essential for event-driven architecture integrations to maintain data integrity and ensure reliable state synchronization across your backend systems.

You validate webhook payloads by applying schema validation, such as using Zod schemas, to verify the incoming data structure and types. This ensures the event data matches expected formats before your backend executes any business logic.

The best way to handle failed webhook deliveries is implementing retry logic alongside dead-letter queues. This approach manages outbound delivery retries and logs failure events for later inspection, preventing data loss during event processing.

Yes, this event-driven architecture approach supports receiving webhooks from GitHub, Shopify, and similar platforms. It implements source-specific signature verification and robust payload validation to securely process events across various external services.

Your endpoint processes duplicate webhooks because it lacks idempotency handling. External services retry event delivery if responses are delayed, so you must implement idempotency keys to prevent executing the same event processing logic twice.
