Application permissions disabled for Yammer in Azure AD

[Tayyab Suhail]

Hi Community,

This is regarding the app registration in Azure AD for authentication/authorization purpose. While setting up the API permissions, there are two types of permissions Delegated and Application. I observed that Application permissions are disabled or not available in case of Yammer.

Is there any specific reason for that or any idea if Microsoft gonna be address this limitation in future ?

Best Regards,

Thank you for taking out time to reply this thread. I do agree that Yammer portal provides application & delegated permissions both so why Microsoft provided only the delegated permissions which we can also achieve through Yammer portal.

Second, i found another way to get access token for consuming Yammer API's. We define the API permissions in the package-solution file of the SPFX solution and once we deploy the package to app catalog, SharePoint takes consent of the admin to grant requested permissions. Once admin gives the consent we can get access token for Yammer through aadHttpClient.
