Get a list of joined participants during a regular meeting

Copper Contributor



I have created a regular meeting and when that meeting starts, I would like to see a list of joined participants in the side panel. This is similar as the People tab that comes with Teams, but I need to check for each participant some status information in an external system.


Now the Graph API /me/onlineMeetings (Get onlineMeeting - Microsoft Graph v1.0 | Microsoft Learn) will only return invited persons for a created meeting. But when the meeting starts at some point, additional persons can join the meeting.


I searched in the area of Meeting Bots, but I cannot find any code samples how to do this. (e.g. ) Most bots are for conversations or adaptive cards, but I have a meeting side panel to show this list. 


I would like to know it this is even possible or not. And if yes, can someone point me to the right direction?

You can subscribe for change notification for online meetings. You can get the below event notification:

CallStarted - Occurs when the meeting call has started.
CallEnded - Occurs when the meeting call has ended.
CallRosterUpdate - Occurs when a participant joins or exits the meeting call.

In CallRosterUpdate you will get the active participants joined and exited list.

Thanks, I will take a look at it. Seems a complex solution for a simple request. Hope the Graph API or so will implement a simple endpoint for retrieving joined participants of a meeting.
