Webhooks & Security 🔒

DocuWriter.ai delivers an event-driven experience via webhooks. Clients register HTTP endpoints to receive real-time notifications for key actions. All webhook payloads carry an HMAC-SHA256 signature to ensure authenticity.

Security

Signature Verification: Each request includes an X-DocuWriter-Signature: sha256= header computed over the JSON body with the subscription's secret .
Event Header: X-DocuWriter-Event indicates the event name.
User-Agent: DocuWriter-Webhook/1.0 is set for all dispatches.

Supported Events 🎉

You can subscribe to:

Event Name	Description
`generation.created`	A new generation is created, such as documentation, tests, diagrams, or optimization.
`generation.updated`	An existing generation is modified.

`repository_sync.suggestion_applied`	An Autopilot suggestion is approved and applied.
