Real-Time Webhook Engine with Signature Verification

Webhooks
Backend

Deliver webhook events (delivered, opened, clicked, bounced) with cryptographic signature headers.

PLANNING

  • Webhook event schema. Defined standardized webhook event payload schemas across packages/webhook-events.

BACKEND

  • Event dispatcher. Dispatches real-time webhook events (delivered, opened, clicked, bounced, spam_complaint).
  • HMAC verification. Added HMAC-SHA256 signature headers on every outgoing webhook payload for tamper-proof verification.
