Unable to request the solutions/virtualEvents/webinars endpoint

Question

My objective is very simple : displaying the list of my organization scheduled webinars in Teams on a webpage using MS Graph API. I have a few webinars planned on the calendar which I want to automatically display in a public webpage. I am able to access webinars in teams without any problem.

I've tried to request the solutions/virtualEvents/webinars endpoint without any success (in beta and 1.0)

• I fetch an access token using the "https://graph.microsoft.com/.default" scope.
• I use the client_credentials flow with the correct EntraID application client_id, tenantid and client_secret fields

I have granted the following permissions to my entreprise application :

The api is always returning an empty collection as following :

{
  "@odata.context":"https://graph.microsoft.com/beta/$metadata#solutions/virtualEvents/webinars",
  "value":[]
}

I also tried the api explorer console and the endpoint gives me a 403 forbidden which I am not able to fix even if I grant the permissions.

I am using an MS 365 business standard licence.

Answer 1

Hello @Antoine BIDAULT ,

Thank you for contacting Microsoft Support.

According to the documentation, the API returns only webinars whose organizer has been assigned an application access policy.

You can refer to documentation for configuring application access policy.

As mentioned in the documentation to run the solutions/virtualEvents/webinars endpoint, we can't use delegated permissions. We get 403 Forbidden error if we use Graph Explorer to run this API. So, we can't use the Graph Explorer.

Hope this helps.

Thank you ! It worked perfectly. The webinars appear in the feed!

For those who had the same issue, I've followed the documentation which requires to use some powershell console in order to allow communication between the Entra application and MS Teams.

I write this in a powershell console :

 Install-Module -Name MicrosoftTeams -Force -AllowClobber
 Connect-MicrosoftTeams

Then I've added a policy :

New-CsApplicationAccessPolicy -Identity TeamAppPolicy -AppIds "06ed3b61-XXXX" -Description "Allow app access"

where 06ed3b61-XXXX is my entreprise application id in Entra

Then I've granted the permission to the potential webinar organizers user id (repeat the operation for each webinar organizers)

Grant-CsApplicationAccessPolicy -PolicyName TeamAppPolicy -Identity "<user-id>"
