# Receive Notification

> Unified webhook notification receiver.

**This endpoint is publicly accessible** -- providers (Microsoft Graph,
Google Pub/Sub, etc.) call it directly.

The ``{service}`` path segment selects the handler:
    - ``outlook``  -- Microsoft Graph push notifications
    - ``gmail``    -- Google Cloud Pub/Sub push notifications
    - (extensible: add new handlers in ``webhook_handlers/``)

Unknown services receive a ``200 OK`` (to prevent provider retries).
