Core Concepts

Sources

A Source is a public webhook endpoint. Providers like Stripe send events to a Source.

Destinations

A Destination is where events are forwarded. This is usually your application.

Pipelines (Fan‑out)

Pipelines connect Sources to Destinations. You can create multiple pipelines per source to fan out events.

Replay

Replay lets you safely resend events after fixing bugs or temporary outages. Replays are tracked and auditable.

Idempotency

Webhook Handoff includes a stable Idempotency-Key header on every delivery. If your endpoint supports idempotent processing, you should use this key to ensure retries and replays do not cause duplicate side effects.
