Office 365 Unified API is now Microsoft Graph, generally available

Office 365 Unified API is now Microsoft Graph, generally available

Back in August I blogged about the Office 365 Unified API, bringing together all the various APIs that cover access to the Office platform. This was interesting because Rob Howard (Program Manager, Office Extensibility Team) mentioned that eventually the APIs for Lync and Skype would also be joining this platform as well:

“The APIs for Lync and Skype will be integrated into this [Office 365 Unified API] structure very soon too.”Rob Howard

Today, at Connect() the Office 365 Unified API was made generally available, and now has a new name, Microsoft Graph.


There’s a new website – making a pretty bold claim taken right out of Lord of the Rings:  One Endpoint To Rule Them All.


The intent is pretty clear. Give developers one place to authenticate and then offer access to all the different Office APIs in a standardized way. It makes a lot of sense. Microsoft also call out 3 distinct advantages:

  • Unified Microsoft API endpoint for accessing the capabilities of the Microsoft cloud.
  • Unified access to data living in the Microsoft cloud.
  • Unified access to intelligence and insights coming from the Microsoft cloud.

Today you can access data about:

  • Users
  • Files
  • Messages
  • Groups
  • Events
  • Contacts (personal)
  • Mail
  • Calendar
  • Devices

You can also Preview (explore):

  • Notifications
  • SDKs
  • People
  • Organizational contacts
  • Office Graph
  • Planner, OneNote, Converged Auth. flow support, OneDrive Files and Outlook.
