Which Azure Active Directory Graph API should I use?

Question

I recently figured out that there are two Graph APIs availble for Azure Active Directory. There is the unified graph.microsoft.com and the AAD specific graph.windows.net:

Azure AD Graph API functionality is also available through Microsoft Graph, a unified API that also includes APIs from other Microsoft services like Outlook, OneDrive, OneNote, Planner, and Office Graph, all accessed through a single endpoint with a single access token.

Is there any reason to use the unifed Graph API when I only need to browse AAD objects? Will the AAD specific graph.windows.net GraphAPI get deprecated?

Answer 1

There has been no announcement of Azure AD Graph API's deprecation and we (and others) use it in production every day.

If you can get what you want through Azure AD Graph API, I'd say use it. If you need something else from the Microsoft Graph API (like emails or contacts), use that one.
