Unfortunately, there is no API to read all uses' scheduled meetings at an account level.

The error message is misleading. It is not allowed a user to read scheduled meetings of another user (even if the reader is a super admin user). The only way to read all is to use access token of each user to read its own meetings.

Thanks. Hope this is the issue. We'll look in to another solution.

So, just to calrify on this users question and your answer...

This API will not pull in all the meeting details, but going to the https://service.ringcentral.com/application/extension/tools/meetings/myMeetings URL will show all the meetings from all the users?

So if we "schedule a meeting for another user" we dont see it in the API, but see it in the UI? Cause when I pull the API for this endpoint I only see meetings that are not scheduled for someone else. So how do we get all the meetings? We have to have each users credentials to check their schedules?

You wrote "So if we schedule a meeting for another user". No, you cannot schedule a meeting for another user. Each user can only schedule meetings for him/herself. The link you shared is about "/myMeetings". Do you see other users' meetings there too?
