  Environment Details

  • Zoom Account Type: Business (single account with multiple users, not a master/sub-account structure)

  • App Type: Server-to-Server OAuth

  • PowerShell Client: PowerShell 7.4 on Windows 10

  • All API requests use: Bearer <access_token> header

  • Token generation via:
    POST https://zoom.us/oauth/token?grant_type=account_credentials&account_id={AccountId}

    Issue Summary

    The app can:

    • Authenticate via OAuth successfully

    • Retrieve all users under the account

      But the app cannot access any past webinar data, even though:

      • Webinars from January 2025 are visible in the web portal under Reports → Webinar Attendance

      • The host user (***********) has a licensed Webinar plan

        It seems the /report/webinars endpoint may require a top-level report:read:admin scope that is not automatically available in the Server-to-Server app UI, or the scopes are not being applied at the full account level for non-master accounts.

        Questions

        1. Does /report/webinars require the explicit report:read:admin scope (not shown in the Marketplace UI)?

        2. For a single Business account (not a master/sub-account), what specific scope or role is needed for the Server-to-Server OAuth app to access /report/webinars and /report/webinars/{webinarId}/participants?

        3. Is this limitation expected for Server-to-Server apps, or can Zoom enable full reporting access upon request?

           ---

           Goal

           We need to export all webinar participant data (name, email, join time, leave time, duration) for all hosts since January 1 2025 into a CSV file for internal reporting.

           Thank you in advance for any clarification or guidance!
           If needed, I can provide request logs or trace IDs for the failing API calls.

           Best regards,
