subscribe to autodesk platform services (aps) webhooks for model derivative, data management, and acc issue/rfi events

Steps

1. Pick the event system and event type to monitor (e.g. systems/data for Data Management, systems/derivative for Model Derivative, systems/autodesk.construction.issues for ACC Issues) — each system exposes its own event catalog.
2. POST to https://developer.api.autodesk.com/webhooks/v1/systems/{system}/events/{event}/hooks with a body containing callbackUrl, scope (e.g. a folder or project scope object), and optional hookAttribute for custom metadata; use "*" as the event to subscribe to all events in a system via systems/{system}/hooks.
3. Send the x-ads-region header (or region query param) to control which region stores the hook and originates callback traffic — the header wins if both are set.
4. Register a signing token via the tokens endpoint so incoming callback payloads can be verified as genuinely from APS.
5. List and audit active hooks with GET hooks, GET app/hooks, GET systems/{system}/hooks, or GET systems/{system}/events/{event}/hooks.
6. Expect autoReactivateHook behavior: APS can auto-deactivate a hook whose callbackUrl stops responding, so monitor hook status and be ready to reactivate/recreate it.
