How to add a teams app to each meeting by default

Question

I have developed an app for teams which greets in the meetings chat every participant. This works fine but I have to manually add the app to the meeting after the meeting is created. Is there a way to add this app to every meeting by default? Can you use Microsoft Graph to identify new meetings and then add the app?

Answer 1

To identify when new Teams meetings are created tenant-wide, consider using the subscription Graph API. You can set up a subscription to receive notifications when changes occur to all events in a user’s mailbox. This way, you’ll be notified whenever a new meeting is created. Also you can use POST /chats/{chat-id}/installedApps this endpoint to add app to new teams chat.

Answer 2

To automatically add your app to every meeting, you can use the Microsoft Graph API to create a subscription for the me/events endpoint. This subscription will notify your app whenever a new meeting is created. https://learn.microsoft.com/en-us/graph/api/subscription-post-subscriptions?view=graph-rest-1.0&tabs=http You can then use the API to add your app to the newly created meeting. https://learn.microsoft.com/en-us/graph/api/chat-post-installedapps?view=graph-rest-1.0&tabs=http Thanks,  Prasad Das *************************************************************************  If the response is helpful, please click "Accept Answer" and upvote it.
