Webhook Security

All webhooks should verify the signature before processing:
  1. Extract signature from header (X-Webhook-Signature or equivalent)
  2. Compute HMAC-SHA256 of the raw request body
  3. Compare signatures using timing-safe comparison
  4. Reject requests with invalid or missing signatures
