Webhooks

There is no outbound webhook delivery today. An integrator cannot register a URL to receive incident or monitor events; the only channel that exists for that is mobile push (see the Notifications section of the console, and the generated Notifications endpoints for device token registration).

The backend has one route under this name, POST /webhooks/paddle, and it is the opposite direction: Paddle (the billing provider) calls it to notify upzero of subscription events, verified with a signature only Paddle and upzero hold. No customer can call it, and it is not the feature this page's name suggests.

This page will describe request signing, retry behavior and payload shape once outbound delivery exists; until then, this is what exists.
