About fasthook
What is fasthook?
fasthook is a webhook gateway that sits between webhook producers (like Stripe, GitHub, Shopify) and your application. It receives, verifies, stores, routes, transforms, retries, and replays webhook events — giving teams a reliable delivery layer before failures reach application code.
What problem does it solve?
Returning 200 OK doesn't guarantee a webhook was processed. Downstream APIs can time out, return 429 or 5xx, credentials rotate, payload schemas change, and retries can cause duplicate side effects. fasthook persists every request, traces each destination attempt, and keeps retries and replay close to the logs engineers need during recovery.
Who is it for?
fasthook is for developers and platform teams that operate production webhook integrations for billing, repositories, commerce, support, or internal automation. It's also useful for testing webhooks with temporary request bins. It is not for teams that only need a simple webhook catcher — fasthook focuses on the operational path: capture, route, inspect, retry, replay.
Real use cases
Route one source (e.g., Stripe) to multiple destinations (CRM, billing, analytics) with filters and transformations. Debug a failed delivery by inspecting request, event, and attempt history. Replay failed deliveries after a receiver or credential recovers. Test webhooks with a temporary bin before building a full workflow.
Key features
- Request capture — Store every inbound request with headers, payloads, query strings, and status before routing.
- Connection routing — Filter, pause, transform, and fan out events to multiple destinations without changing producer or destination code.
- Destination attempts — Track response status, body, latency, and errors for each delivery.
- Retries and replay — Retry failed deliveries and replay events after a receiver or downstream service recovers.
- Request bins — Create temporary URLs for quick webhook testing.
- Inspection history — Trace requests, events, and attempts to debug delivery state.
- Operational docs — Integration guides for Stripe, GitHub, Shopify, Slack, n8n, and more.
