Microsoft Graph
Microsoft Graph is the unified REST endpoint for Microsoft 365, Windows, and Entra ID (Azure AD) data — mail, calendar, files, Teams, users, groups, and device management all live under a single v1.0 or beta namespace. Every call needs an OAuth 2.0 bearer token issued through the Microsoft identity platform and scoped to the specific resources the app may touch; some resources additionally require an appropriate Microsoft 365 or Entra ID premium license behind the scenes.
