Making with Microsoft Graph an OnlineMeeting object error 403 - php

Question

Im doing and application with PHP, which use Microsoft Graph API. Actually i couldnt found any documentation for php, so im follow microsoft tutorial.
So first i tried to do the microsoft page example for post method:
POST https://graph.microsoft.com/beta/app/onlineMeetings
Content-Type: application/json
Content-Length: 1553
{
"meetingType": "meetNow",
"participants": {
"organizer": {
"identity": {
"user": {
"id": <id user azuread teenant>
}
}
}
},
"subject": "subject-value"
}
actually it doesnt work on microsoft graph explorer. I already gave all permissions and ir returns the following:
Failure - Status Code 403, 440ms Looks like you may not have the permissions for this call.
{
"error": {
"code": "Forbidden",
"message": "",
"innerError": {
"request-id": "fd8cdedd-99f1-4bca-9de6-29a77f834bba",
"date": "2019-04-25T18:06:43"
}
}
}
I though explorer dont work with onlinemeetings and calls, so i stopped to use it, and i tried on a php app.
Then i tried this:
// Create a Graph client
// Set graph version
// Get user info
$graph = new Graph();
$graph->setAccessToken($accessToken);
$graph->setApiVersion("beta");
$createTeamsUrl = '/app/onlineMeetings';
$events = $graph->createRequest('POST', $createTeamsUrl)
->attachBody($body)
->execute();
accessToken is the returned token from oauth v2.0, and it works.
I already gave to my azure ad aaplication all permissions for test purpuoses (including delegated and app such as OnlineMeetings.ReadWrite.All), but this returns the same error.
I did some others request, like this:
//works
$graph = new Graph();
$graph->setAccessToken($accessToken->getToken());
$user = $graph->createRequest('GET', '/me')
->setReturnType(Model\User::class)
->execute();
and this works.
I also downloaded c# sample, and it works, so i think its not permissions

If anyone knows if this is supported or not, could be useful.
Thanks.

Answer 1

If you are using common as tenant to get the access token, first thing you have to do is use your tenant id instead of common word, as explained here. This worked for me.

Answer 2

Getting same 403 forbidden error on creating online meeting
also added "OnlineMeetings.ReadWrite.All" permission in the scope
