Hello, I am building a Server-to-Server OAuth app to programmatically retrieve answers submitted on our Zoom Scheduler booking page (specifically the `custom_values` field for attendees). According to the Zoom Scheduler API documentation for: ```auto GET /v2/scheduler/events/{eventId}/attendees/{attendeeId} ``` this endpoint requires the following scopes: - `scheduler:read:scheduled_event_attendee` - `scheduler:read:scheduled_event_attendee:admin` However, in the Zoom Marketplace scope configuration for Server-to-Server OAuth apps, the scope: ```auto scheduler:read:scheduled_event_attendee:admin ``` is not available for selection. Currently, only the following related scope appears: ```auto scheduler:read:scheduled_event_attendee:master ``` When calling the endpoint, we receive the following error: ```auto 401 Invalid access token, does not contain scopes: [scheduler:read:scheduled_event_attendee, scheduler:read:scheduled_event_attendee:admin] ``` Could you please clarify: 1. Is `scheduler:read:scheduled_event_attendee:admin` required for this endpoint? 2. If so, why is it not available for Server-to-Server OAuth apps? 3. Is there an alternative scope that should be used to retrieve the `custom_values` field? For context: - We are using a Server-to-Server OAuth app. - The booking page and API app belong to the same Zoom account. - We are attempting to retrieve attendee Q&A data for scheduler events. Thank you. ---

Hi @Otovee Thanks for reaching out to us! Can you please confirm that your role has the right setting and permissions? I am able to see the scope in my test account so it might be a permissions issue. ---
