# Webhooks

Webhooks let you push QACrow events into Slack, GitHub, your CI, or anywhere that can accept an HTTP request.

Create one from **API & Webhooks → Webhooks** with:

- **URL** — your endpoint.
- **Events** — pick which events to subscribe to (e.g. `run.completed`, `run.failed`, `issue.critical`).

Each delivery is signed with HMAC-SHA256 using a shared secret. Verify the `QACrow-Signature` header before trusting the payload.

See [API → Webhook payload](/content/docs/api/webhooks/index.html) for the schema.
