Microsoft Graph API

Microsoft Graph is the unified REST API endpoint: your gateway to data and intelligence across Microsoft 365, Windows, and Enterprise Mobility + Security.

The Microsoft Graph API provides a single, unified endpoint: `https://graph.microsoft.com`. This is the core access point for Microsoft 365 data, enabling programmatic interaction with services like Exchange Online, SharePoint, and Teams. Developers leverage this to build intelligent applications that access essential resources: user profiles, calendar events, files in OneDrive, and email messages. The API uses a robust RESTful model, supporting both v1.0 and beta versions, allowing you to connect millions of users to custom business logic and drive productivity scenarios.
