Getting Forbidden 403 error while creating OnlineMeeting using Microsoft Graph api

Question

I am trying to create online meeting through https://graph.microsoft.com/beta/communications/onlineMeetings . initially i got the 403 Forbidden error. then i give the Delegated and Application permissions(OnlineMeetings.ReadWrite,OnlineMeetings.ReadWrite.All) on my registered app on azure.then 403 error is gone and i got new error 400 bad request(Organizer.Identity.User.Id missing). then i supply Online meeting post request as follows-:

{
  "startDateTime":"2020-04-20T14:33:30.8546353-07:00",
  "endDateTime":"2020-04-20T15:03:30.8566356-07:00",
  "subject":"Application Token Meeting",
  "participants": {
    "organizer": {
      "identity": {
        "user": {
          "id": "cb6d6636-1c9e-457c-b904-5da8265a8927"
        }
      }
    }
  }
}

again i got 403 Forbidden error. i created user with the help of https://graph.microsoft.com/v1.0/users and https://graph.microsoft.com/beta/invitations. user is created in my app on azure and i give the permission (User.ReadWrite.All, Directory.ReadWrite.All, Directory.AccessAsUser.All,User.ReadWrite.All, Directory.ReadWrite.All) but error(403) did not change.

My question is that how to give user authorization in microsoft graph API.

The required permission is Delegated Permission: OnlineMeetings.ReadWrite. See reference here.

403 error means your access token doesn't include the required permission. You can add it like this:

Don't forget to click on "Grant admin consent for {your tenant}".

You should implement Get access on behalf of a user and get an access token to call /communications/onlineMeetings endpoint.

The http sample for your reference:

POST https://graph.microsoft.com/beta/communications/onlineMeetings
Content-Type: application/json
Authorization: Bearer {access token}

{
  "startDateTime":"2019-09-09T14:33:30.8546353-07:00",
  "endDateTime":"2019-09-09T15:03:30.8566356-07:00",
  "subject":"Application Token Meeting",
  "participants": {
    "organizer": {
      "identity": {
        "user": {
          "id": "550fae72-d251-43ec-868c-373732c2704f"
        }
      }
    }
  }
}

You can learn more details about Use the access token to call Microsoft Graph. Don't forget to put Authorization: Bearer {access token} in the request headers.
