Invitation Manager Microsoft Graph Security Permissions – Critical Detail
The invitations “service” is part of Graph not part of AD.
AD looks like it is part of Graph and Graph looks like it is part of AD but they have different security setup contexts and scopes that happen to have the exact same permission names in some of the scopes.
If you are setting up an application in Azure that needs access to the Invitations API then make sure you add a specific reference to Graph in addition to the AD API reference that is created for you when you first create an application registration.
FYI: The Invitations looks like it is part of normal full v1.0 Graph and not beta only anymore. https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/resources/invitation https://developer.microsoft.com/en-us/graph/docs/api-reference/v1.0/api/invitation_post https://graph.microsoft.com/v1.0/invitations https://graph.microsoft.com/beta/invitations
