Webhook Design

Purpose

Design and implement secure webhook receivers that handle events from external systems reliably with proper security, idempotency, and error handling.

When to Use

• Receiving events from third-party services (Stripe, GitHub, Slack)
• Building event-driven architectures
• Implementing real-time integrations
• Processing asynchronous notifications
• Handling payment/order updates

Key Capabilities

1. Security - Validate webhook signatures (HMAC, JWT)
2. Idempotency - Handle duplicate events safely
3. Reliability - Retry failed processing, handle errors gracefully
