Power Automate JSON add co-organizer

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. ...

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"
}
]
}
}

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?

  samb2180 I had been using Group 'Send an HTTP request V2' connector. I changed it to HTTP premium. Now I'm running into an issue with the Header in HTTP. I'm not sure what to enter for Authorization'. And I don't know if I need an app registration. Seems as if I do. I'll have to ask my engineer to do that since I don't have rights. Plus I realize I may not have everything correct in the Body.

    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-75fa1c6696ea
    
    The 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.
