GET - OnlineMeetings always return 404

Question

Hello, I'm trying to get the onlineMeeting object, tried using the joinWebUrl filter, but it always return a 404.

endpoint I'm using is /v1.0/users/{user}/onlineMeetings?$filter=JoinWebUrl eq 'URL'

Tried to url encode everytthing after the JoinWebUrl (to remove spaces and other characters)

My sample URL:

https://graph.microsoft.com/v1.0/users/******@latam.stefanini.com/onlineMeetings?$filter=JoinWebUrl%20eq%20 'https://teams.microsoft.com/l/meetup-join/19:meeting_ZjJlMWQ3YTMtZWI5Yy00ZTNiLTg4YmUtNDgyZTdkYWExNGEw%40thread.v2/0?context={"Tid"%3a"d8bde65a-3ded-4346-9518-670204e6e184"%2c"Oid"%3a"ceff7fa8-b5a8-4776-afca-63b07fe42956"}'

Kindly let me know what can be done to solve it as the link is valid and if I list this meeting using the /events endpoint, it is also there.

Also I would like to know if the ID given on the events endpoint is the onlineMeeting ID, because if it is it also returns a 404 status (/onlineMeetings/{id})

Always receive this json as the result:

{     "error": {         "code": "UnknownError",         "message": "",         "innerError": {             "date": "2025-01-22T03:47:10",             "request-id": "4ec2d9ac-dfc6-4a89-843c-a7f47c5b896b",             "client-request-id": "8602d002-0404-8224-80af-96fe9502cce7"         }     } }

Hi @Marcelo Schoen

After many tests, I found the problem. This API does not support UPN yet, you must use the user's ID to get the online meeting.

GET /users/{userId}/onlineMeetings?$filter=JoinWebUrl%20eq%20'{joinWebUrl}'

Hope this helps.

Hi @Marcelo Schoen

The online meeting id is not the event id, you cannot get the online meeting id by calling the event endpoint. If you are creating an event and enabling it as an online meeting, you will get a joinUrl, through which you can retrieve the online meeting.

Please note that when getting the online meeting of a user in application-only context, you must ensure that the target user is the organizer or attendee of the current online meeting.
