Welcome

Learn the concepts behind how Repost receives webhooks: buckets, forwarders, and bucket modes.

Repost sits between webhook senders and your application. Providers send events to a bucket, Repost records the request, and forwarders deliver it to the services that should act on it.

Core concepts

Repost is built around a few ideas: where events enter, where they go, and how the bucket responds, then how you inspect, search, replay, and recover the traffic that flows through.

Buckets

A bucket is the address you give to a webhook provider. It owns the event history, forwarding rules, and response behavior for that stream of traffic.

Stable source URL

Use one Repost endpoint instead of wiring every provider directly to your application.

Clear boundary

Split buckets by provider, environment, product area, or any other operational boundary.

Controlled behavior

Choose a bucket mode before sending traffic so the provider gets the right response.

Forwarders

A forwarder connects a bucket to a destination. A destination can be your production API, a worker, an internal service, or a local development session.

1
Receive

A provider sends the webhook to the bucket URL.

2
Record

Repost stores the inbound request with the bucket event history.

3
Deliver

Each active forwarder sends the event to its destination.

4
Inspect

The event page shows the request, forwarders, and responses in one place.

Bucket modes

Bucket mode decides what the webhook sender receives after it calls Repost.

Acknowledge first, deliver after
The default. The sender gets an immediate acknowledgement, then Repost delivers to your destinations asynchronously, with retries, backoff, and a dead-letter queue, so nothing is lost when an endpoint is down.
Immediate acknowledgement

Repost answers the provider right away, then delivers in the background.

Fan out to many forwarders

Send the same event to your API, a worker, analytics, or local development.

Reliable and recoverable

Retries with backoff, a dead-letter queue and replay, functions, secrets, and rate limiting.

Event history

Every event a bucket receives is recorded with its delivery outcomes, so you can confirm what the provider sent, where it went, and what each destination returned.

Request context

Method, headers, body, source, timestamp, and the bucket that received the event.

Delivery context

Forwarders, destination responses, and whether an event should be sent again.
