startRTMS() returns success, but meeting.rtms_started webhook never arrives / failed to access meeting content

Hi Zoom Developers,

I’m trying to enable RTMS for a Zoom App / General app and need help identifying the missing configuration, entitlement, or developer-plan requirement.

Summary:

  • zoomSdk.startRTMS() returns successfully in the Zoom Meeting client.
  • Zoom then shows an in-client message such as “failed to access meeting content” / “This app is disabled. Contact your organization’s admin for support.”
  • The meeting.rtms_started webhook never reaches our RTMS endpoint.
  • Our server/worker receives zero inbound traffic, so this appears to fail before Zoom connects to our backend.

App / environment:

  • App type: General app / Zoom App, user-managed
  • Mode: Production Beta Test / internal testing
  • Host: signed in as account admin/authorized user
  • Meeting: scheduled Zoom meeting, hosted by the authorized admin user
  • Account setting “Share realtime meeting content with apps” is enabled
  • App is installed/authorized for the host/admin user
  • Auto-start/access for shared realtime meeting content is enabled for the app

Scopes currently enabled:

  • zoomapp:inmeeting
  • meeting:write:open_app
  • meeting:read:meeting_audio
  • rtms:read:rtms_started
  • rtms:read:rtms_stopped
  • rtms:read:rtms_interrupted

Event subscriptions:

  • meeting.rtms_started
  • meeting.rtms_stopped
  • meeting.rtms_interrupted

Endpoint:

  • Event notification endpoint is configured and publicly reachable over HTTPS.
  • RTMS worker health check is healthy.
  • We see no request logs, no edge/WAF logs, and no webhook traffic when startRTMS() is called.

Observed client flow:

  1. User starts Guide session inside Zoom app.
  2. App calls zoomSdk.config().
  3. App calls zoomSdk.startRTMS().
  4. startRTMS() returns success.
  5. Zoom does not report an active RTMS stream.
  6. No meeting.rtms_started event is delivered to our endpoint.

Additional context:
I was advised that RTMS access may require purchasing developer/SDK credits or enabling a developer plan. I purchased $100 of developer SDK credits because I believed that was the path to enable RTMS access. However, RTMS still does not start successfully, and meeting.rtms_started is still never delivered to our endpoint.

Zoom Support said this is likely an account-level provisioning, app capability configuration, or authorization state problem, but closed the ticket and directed us here.

Questions:

  1. Can RTMS be tested in Production Beta Test mode before public Marketplace publication/review?
  2. Does RTMS require backend enablement/allowlisting even after the RTMS request form is submitted?
  3. Is public Marketplace publication required before meeting:read:meeting_audio and RTMS events actually work?
  4. What exact configuration causes startRTMS() to return success while Zoom still blocks meeting content access?
  5. Is “This app is disabled. Contact your organization’s admin” related to RTMS meeting-content authorization, app activation state, or account-level RTMS provisioning?
  6. Do Zoom Build Platform SDK credits enable RTMS access, or is RTMS specifically tied to the Zoom Developer Pack / pay-as-you-go plan?
  7. If credits were purchased under the wrong developer product, can they be applied to RTMS access, or is a separate Developer Pack subscription required?

Any guidance on the required app/account state for beta testing RTMS would be appreciated.Before Creating a New Topic:

@DavidA15 you will need to sign up for a developer pack here to enable RTMS on your account https://zoom.us/pricing/developer

Hi Chun Siong, thank you for responding. I believe I purchased 500 developer credits a week or so ago (see below) but RTMS not working. If this is not what I needed to purchase, could you point me in the right direction to purchase what I need? Thank you

@DavidA15 there is no developer pack enabled on your account.

Hi Chun Siong, it looks like it isn’t available to purchase on my account. How do I get the option to purchase enabled?
