Video SDK Webhooks validated but not firing (New Standalone Paid Account)

Hello,

I recently moved from a free Video SDK account to a new Video SDK Standalone Paid Account. I have a critical issue: webhooks are not firing/shooting at all, even though the endpoint is correctly validated.

Endpoint Status: Validated (returns 200 OK with the proper encryptedToken). Same C# (.NET) code that worked perfectly in my previous SDK account.

Technical Details:

  • App ID: naW7Ur5hSqmfon7THRonzg
  • Account Number: 5157444889
  • Video SDK type and version: Standalone v2.3.12

Troubleshooting done:

1. Consolidated all events into a single subscription.
2. Verified SDK Key/Secret and Secret Token match perfectly in my backend.
3. Sessions are being created, joined, and even Cloud Recordings are generated successfully.
4. Ngrok/Server logs show the validation request from Zoom, but ZERO traffic for session events (started, ended, user_joined, etc).

Since Support ticket #TS2279047 told me this was a “configuration issue” but everything seems correct on the dashboard, could an engineer please check if there is a syncing issue or a missing feature flag for this new account?
