Meetings API / open_apps: Authenticated user has not permitted access to the targeted resource

[noy]

I have three users collaborating on the same meeting - one is the host, the other two are participants.
My flow is as follows:

1. [Host] Creates a new meeting and invites both participants
2. [Participant 1] Calls https://api.zoom.us/v2/meetings/{double_encoded_created_meeting_uuid}/open_apps
   I’m getting the following response:

API request failed: {
  url: 'https://api.zoom.us/v2/meetings/{double_encoded_created_meeting_uuid}/open_apps',
  method: 'POST',
  status: 403,
  statusText: 'Forbidden',
  error: '{"code":403,"message":"Authenticated user has not permitted access to the targeted resource."}'
}

I’ve seen it might have something to do with shared access permissions but I’m not sure why or is it really the case here.
Any help would be greatly appreciated.

Thanks,
Noy

Hi @noy
Thanks for reaching out to us!
I am not able to replicate this on my end. Could you let me know if you are making this call while the meeting is Live? Also what app type are you using? I tested this with S2S app, but want to run some tests using the same app than you

The meeting is live, and I’m using client (three legged oauth) app

Hey @noy
This endpoint is supposed to be used before the meeting starts, so the error you are seeing is expected

I’m getting the same result before a meeting has started though

Could you share with me the request body you are sending?
