Microsoft Graph exposes multiple APIs from Office 365 and other Microsoft cloud services through a single endpoint: https://graph.microsoft.com. Microsoft Graph simplifies queries that would otherwise be more complex.
You can use Microsoft Graph to:
Microsoft Graph development stack

Microsoft Graph exposes two endpoints: /v1.0 and /beta. The /v1.0 endpoint includes the resources that you can access in your production app. The /beta endpoint includes APIs that are currently in preview. The following table lists some common queries that you can use to access the Microsoft Graph API.
Note: The APIs in the beta endpoint are subject to change. We don't recommend that you use them in your production apps.
