Hi @Phong Vu,
We are unable to Graduate our app as it says we haven't exercised all the requested permissions. I've re-run my web hooks multiple times and still they are not registering.
The permissions tab shows no Webhooks
But on the response times tab you can see the requests. Somewhere RingCentral knows about my webhook subscriptions GET POST and DELETE requests.
