How to track multiple Microsoft Entra resource types with one delta query
Microsoft Graph delta query is usually associated with a single resource collection. You call endpoints such as /users/delta, /groups/delta, or /applications/delta, complete the initial synchronization, and then save a delta link for that collection.
There is, however, an interesting exception for Microsoft Entra directory data. The directoryObject: delta endpoint can track several directory object types through one delta query and one state token.
In this article, I will show how the endpoint works and how it can be used to maintain a unified local inventory of users, groups, and devices.
