How to specify participants when creating new Teams meeting using onlineMeetings API

I am trying to create Teams meetings programmatically using the onlineMeetings API endpoint. I'm having trouble setting the meeting attendees. Although I specify a valid UPN, user id, Azure AD tenant ID, and role of 'presenter', the attendee is added using 'MSA' (Microsoft account?) with a role of 'attendee' - see below.

Can anyone advise if I'm missing something?

Thanks!!

Relevant part of my request:

     "participants": {
         "attendees": [
             {
                 "upn": "<upn>",
                 "role": "presenter",
                 "identity": {
                     "user": {
                         "id": "<user id>",
                         "tenantId": "<tenant id>",
                         "identityProvider": "AAD"
                     }
                 }
             }
         ]
     }

The response from Graph API:

     "participants": {
         "attendees": [
             {
                 "upn": "<upn>",
                 "role": null,
                 "identity": {
                     "phone": null,
                     "guest": null,
                     "encrypted": null,
                     "onPremises": null,
                     "applicationInstance": null,
                     "application": null,
                     "device": null,
                     "user": {
                         "id": "<user id>",
                         "displayName": null,
                         "tenantId": null,
                         "identityProvider": "MSA"
                     }
                 }
             }
         ],

If you already created a new onlinemeeting and want to add participants then you can use participants property to do it in the request body - the participants associated with the online meeting. This includes the organizer and the attendees.
Also if you're updating/adjusting the attendees field of the participants property, such as adding or removing an attendee to the meeting, always requires the full list of attendees in the request body.

Hey @Deva-MSFT , thanks for your reply.

Yes I think that's what I'm doing in my code block above. The problem is the API doesn't recognise the 'role' property that I'm setting and so defaults everyone to 'attendee', even when I choose 'presenter'. Also, it doesn't recognise the user's AAD account and returns 'MSA' as the identity provider, even though I specify a user ID and tenant ID.

Hi @tedo99/anonymous user , we cannot assign a role using programmatically, by default it will taken as attendee. you can use this example for your scenario.

Same problem. When attempting to set an attendee role as "presenter", the role was assigned as "attendee". Has anyone solved this yet or found a workaround?

The following worked for me.

By default, every attendee can present, so the API won't allow you to set an attendee's role to presenter unless you also change allowedPresenters to roleIsPresenter. See https://docs.microsoft.com/en-us/graph/api/resources/onlinemeeting?view=graph-rest-1.0#onlinemeetingpresenters-values
