RTMS webhooks not firing — need RTMS enabled on Developer Pack account

Hi Zoom team,

I signed up for the Zoom Developer Pack yesterday (account email: callum.frogson@outlook.com) and I’m building a meeting notes bot using RTMS. I’ve completed the full setup but meeting.rtms_started webhooks never arrive when I start a meeting.

What I’ve done:

  • Created a General App (User-managed) in Marketplace
  • Added scopes: rtms:read:rtms_started, rtms:read:rtms_stopped, meeting:read:meeting_audio, meeting:read:meeting_transcript, meeting:read:meeting_video, meeting:read:meeting_chat
  • Created an event subscription for meeting.rtms_started and meeting.rtms_stopped with a working webhook URL (validated and reachable)
  • Installed the app via OAuth — token confirms all scopes are granted
  • Started Zoom meetings — zero POSTs ever arrive from Zoom to our endpoint

Everything on the app/code side is working correctly (I can simulate the webhooks and they process correctly). The issue is that Zoom never sends meeting.rtms_started.

Could you confirm whether RTMS is enabled for my account, or enable it? My app Client ID is cYTLsC1PTiCRNLMNIW1_xg.

Thanks

@Callumfrogson you will need to enable auto start, or call the REST API to start RTMS to trigger the webhook event to fire.
