I am trying to access the Online Meetings Graph API (Beta version) using developer tenant. I am able to login successfully to the developer tenant but not able to get the Token to access the graph API for Application type graph APIs. I am able to get the token for delegated type Graph APIs successfully and able to connect to the Graph API. I given the admin consent for these APIs using button "Grant admin consent for [0]" in Azure Active Directory => App Registrations => My App => API Permissions in the Azure portal. I am able to see the success message as "Granted for [my Tenant]".
But I am getting the error saying "AADSTS65001: The user or administrator has not consented to use the application" while getting the token. I am using ConfidentialClientApplication class and AcquireTokenByAuthorizationCodeAsync method to get the token.
So is there any other place I need to verify for the consent or for developer Tenant and for these Beta APIs, I need to check any other process ?
Thank You for Your Time, Rishi
I tried for delegated APIs (User.Read and Contacts.Read) and working fine on developer tenant. While doing trail and error I got error saying Invalid Scope (OnlineMeetings.ReadWrite.All) couple of times.
