Microsoft Graph API
Microsoft Graph API is a unified RESTful API endpoint that provides access to data and intelligence across Microsoft 365 services, including Outlook, OneDrive, SharePoint, Teams, and Azure Active Directory. It allows developers to integrate with Microsoft's ecosystem by enabling CRUD operations on user data, files, calendars, and organizational resources. The API uses OAuth 2.0 for authentication and returns data in JSON format, supporting web, mobile, and desktop applications.
Developers should learn Microsoft Graph API when building applications that need to interact with Microsoft 365 services, such as automating workflows in Teams, syncing files from OneDrive, or managing user identities in Azure AD. It is essential for enterprise applications that require seamless integration with Office tools, enabling scenarios like document collaboration, email automation, and data analytics across Microsoft platforms. Using Graph API simplifies development by providing a single endpoint instead of multiple service-specific APIs.
