# Outbound webhooks

> Let your app notify external services — Slack, Zapier, partner systems — with signed deliveries and automatic retries.

When your app needs to tell another system something happened — post to a Slack
channel on a new order, trigger a Zapier or n8n flow, notify a partner API —
outbound webhooks handle delivery properly, so one transient outage at the
receiving end doesn't mean a lost event.

## What your app gets

* **Registered endpoints**: each destination (say, `slack-alerts`) is configured
  once with its URL and optional signing secret.
* **Reliable delivery**: events are queued and delivered with automatic
  exponential-backoff retries over hours, not a single fire-and-forget attempt.
  Exhausted deliveries are kept, not discarded — they can be retried manually
  after the receiver recovers.
* **Signed payloads**: deliveries can carry a Stripe-style HMAC signature so the
  receiver can prove the event really came from your app.
* **A full audit trail**: every attempt and outcome is recorded per project —
  ask the agent for the delivery history of any endpoint.

## Every delivery carries

* a unique **delivery ID** (receivers use it to deduplicate retries),
* the **event type** you assigned (receivers use it for routing),
* the **signature** when the endpoint is configured with a signing secret.

## Good to know

* Destination URLs must be HTTPS.
* Signing secrets live in your project's [secret store](/capabilities/secrets).
* This replaces the fragile pattern of a bare `fetch()` in a request handler —
  the agent uses it whenever your app promises to notify an external system,
  which also makes that promise [verifiable](/verification/what-verified-means).
