API Reference
Webhooks
Register endpoints; inspect deliveries; rotate secrets; replay.
Endpoints
Returns:
signingSecret is shown only once. Save it into your secrets
manager before you close the response.
Deliveries
Replay puts the delivery back on the queue. Handy for debugging a receiver: fix the bug, replay the last few failures, watch them land.
SSRF guard
Endpoint URLs must:
- Use
https:// - Not resolve to private (RFC 1918), loopback, link-local, or CGNAT addresses
- Be DNS-resolvable at registration time
The check runs again on every delivery, so an endpoint that starts resolving to internal infra later (DNS rebinding) gets blocked at send time.
Auto-disable
5+ permanent failures in a 24-hour window → endpoint flips to disabled automatically. Re-enable from the dashboard once your server is back online.
See the Webhooks guide for signature verification.
