Webhook Development

This handles the full webhook lifecycle: event schemas, signature verification, retry logic with exponential backoff, and dead-letter queues for failed deliveries. You'd reach for this when building event-driven integrations, like notifying external systems about orders or payment events, or when you need reliable async communication between services. The references include Node.js and Python implementations with working examples of HMAC signature validation and configurable retry strategies. One thing to note: webhook reliability is harder than it looks, so the retry and idempotency patterns here will save you from debugging production delivery failures at 2am.

Quick Start

Minimal working example:

{
  "id": "evt_1234567890",
  "timestamp": "2025-01-15T10:30:00Z",
  "event": "order.created",
  "version": "1.0",
  "data": {
    "orderId": "ORD-123456",
    "customerId": "CUST-789",
    "amount": 99.99,
    "currency": "USD",
    "items": [
      {
        "productId": "PROD-001",
        "quantity": 2,
        "price": 49.99
      }
    ],
    "status": "pending"
  },
  "attempt": 1,
  "retryable": true
}
