Creating an Online Meeting with ThreadId Using Graph API

Question

I am trying to create an Online Meeting in a Teams channel using the Graph API with the beta endpoint (/beta/me/onlineMeetings/). I am including a threadId in the chatInfo properties, but for some reason, the join button is not visible, and the word "ended" is appended to the end of the meeting subject immediately.

Here’s the result:

Below is the HTTP request used to create the Online Meeting:

POST https://graph.microsoft.com/beta/me/onlineMeetings

{
  "subject": "Team Strategy Meeting - 4",
  "startDateTime": "2024-12-10T14:30:00Z",
  "endDateTime": "2024-12-10T15:30:00Z",
  "chatInfo": {
    "threadId": "......@thread.ta...."
  },
  "participants": {
    "attendees": [
      {
        "identity": {
          "user": {
            "id": "",
            "displayName": "Jane Doe"
          }
        }
      }
    ]
  }
}

Is the issue related to missing information or is it because I am using the beta API?

Hi @Alain Groleau

Thanks for reaching out to Microsoft!

As per documentation property chatInfo is the chat information associated with the online meeting created.

The threadID for the meeting looks similar to this-

"chatInfo": {

    "threadId": "19:meeting_M2IzYzczNTItYzUtYmFiMjNlOTY4MGEz@thread.skype"}

The channelID of the teams which looks "19:1gLU0U5Rh1YtgBU4AqgLx1O-q4USgsEUAJwfnWn90vM1@thread.tacv2"

Since the IDs are different, this will lead to incorrect values being passed for chatInfo.

Note: APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

Hope this helps.
