Webhooks
Receive signed, real-time event notifications at your own endpoint.
Webhooks push events to your application as they happen — a delivery, a bounce, a contact change — so you can react without polling. Register a public HTTPS endpoint, subscribe to the events (or categories) you care about, and we POST a signed payload whenever one fires.
Full reference in the Webhooks guide
This page manages your endpoints; the API-reference Webhooks guide covers the payload shapes, signature verification (including timestamp tolerance), the retry schedule, the HTTPS/SSRF requirement, and rotating the signing secret. Read it before wiring up your verifier.
Each endpoint shows a live health state — Enabled, Failing, or auto-Disabled after sustained failures — so a dead URL surfaces early. Use Send test to fire a sample signed event and confirm your handler works end to end.
