Graph API error: InvalidAuthenticationToken error when requesting omlinemeeting: CreateOrGet.

Question

I would like to call the onlinemeeting:CreateOrGet API from an application built with the no-code tool bubble using an application token.

onlineMeeting: createOrGet

When I request the API, I get an "InvalidAuthenticationTokenv" error.
Can you please tell me where I am going wrong in the steps so far?

• Register my app with AzureAD
  Register the web app to be built by Bubble. Set up the redirect URI, client secret, etc.
  
• Configure the necessary API permissions in CreateOrGet and get the admin permission from AzureAD.
  
• Get an access token without user.
  Get access without a user

• Request and response for CreateOrGet.

Thanks in advance.

Answer 1

I noticed that you are requesting the token of your custom api. Obviously, the token of the custom api cannot call MS graph api, so you only need to change the scope to: https://graph.microsoft.com/.default.

By the way, when you use application permissions, your administrator must create application access policy and grant users, please pay attention to the description of the document.
