Hi, I can create a Teams meeting using JSON and an Azure AD HTTP request but is it possible to add co-organizers as part of the request. I can't figure it out but hope someone can suggest a method.Cheers, Jon

Hi BBeck88, The HTTP premium connector is commonly used for app permission, so you need to create the app in your azure admin portall and all the stuff to the get the bearer token. You can check here how to do it:https://iamrehanmemon.medium.com/generate-authentication-bearer-token-in-power-automate-using-azure-app-registration-75fa1c6696eaThe others HTTP connectors available in Power Automate use delegated permissions. Note that not all the HTTP actions accept all the endpoints. The error you are getting is because the connector does not accept this graph endpoint.You can try to use the HTTP request with Microsoft Entra ID (preauthrized) action (not sure if it will work). When you first time use this action, it will ask you for the Base Resource URL and the Microsoft Entra ID Resource URI. You can use https://graph.microsoft.com for both.

jonlake What do you mean by Co-Organizers? do you mean Required Attendees? It would be good if you can share some screen shot of your Power Automate to see which API you are using to creates Teams meetings

kalpeshvaghela you can open a meeting from the Teams calendar then choose meeting options, from where you can add meeting co-organizers. I need to be able to do that using Power Automate, and likely JSON (which creates the meeting initially). Ideally I'd be able to create the event and set all options using a JSON post.

jonlake According to Official documentation of Graph API, it's not possible to add multiple co-organizers while adding meeting or updating meeting using Graph API. It's not even possible with beta version of graph API.https://docs.microsoft.com/en-us/graph/api/user-post-events?view=graph-rest-beta&tabs=httpEvent JSON Object Schema - https://docs.microsoft.com/en-us/graph/api/resources/event?view=graph-rest-beta#properties - Here organizer is the single property where you can provide only one user.

jonlake yes, you can. Just use the onlinemeetings patch.PATCH /users/{userId}/onlineMeetings/{meetingId}Be sure to include the header Prefer: include-unknown-enum-members.The json should include the already existing attendees, including the new one.{"participants": {"attendees": [{"upn": "existingattendee1upn","role": "attendee"},{"upn": "existingattendee2upn","role": "attendee"},{"upn": "newcoorganizerupn","role": "coorganizer"}]}}

PATCH /users/{userId}/onlineMeetings/{meetingId}

Be sure to include the header Prefer: include-unknown-enum-members.

The json should include the already existing attendees, including the new one.

{
"participants": {
"attendees": [
{
"upn": "existingattendee1upn",
"role": "attendee"
},
{
"upn": "existingattendee2upn",
"role": "attendee"
},
{
"upn": "newcoorganizerupn",
"role": "coorganizer"
}
]
}
}

  Hi samb2180. I've been testing PATCH /users/{userId}/onlineMeetings/{meetingId}, but I keep getting this error - URI path is not a valid Graph endpoint, path is neither absolute nor relative or resource/object is not supported for this connector. I'm confused because you've explained its possible and MS Learn documents it here - https://learn.microsoft.com/en-us/graph/api/onlinemeeting-update?view=graph-rest-1.0&tabs=http. I wasn't sure if I entered the header in the correct area or what I have wrong. I put 'Prefer: include-unknown-enum-members' (with no '') in CustomHeader1 field. My URI is https://graph.microsoft.com/v1.0/users/<my userID>/onlineMeetings/<meetingID> (from dynamic content). I've been trying this with 'GET' but maybe that's what I'm doing wrong.

    Which action are you using? In my case I'm using the premium HTTP action with app permissions.
    
    Are you using the HTTP with Microsoft Entra ID connector?
