Office 365 APIs

This site contains the documentation for Office 365 REST APIs exposed on the OneNote and Outlook endpoints. The documentation is no longer actively updated. It is here for your reference, in case you have already included any of the API in your project.

Office 365 services, such as OneNote, Outlook, Excel, OneDrive, Microsoft Teams, Planner, and SharePoint, are now exposed in Microsoft Graph. Microsoft Graph is a unified API endpoint for accessing data across Microsoft 365, which includes Office 365, Enterprise Mobility, and Security and Windows services. It provides a simplified developer experience, with one endpoint and a single authentication token that gives your app access to data across all these services.

Our recommendation:

  • If you are starting a new app, please use Microsoft Graph.
  • If you are maintaining an existing project, use this documentation set for reference. In addition, plan your move to the latest APIs in Microsoft Graph to take advantage of all the new functionality and innovation there.
  • If you are adding new functionality to an existing project, integrate that new functionality by using Microsoft Graph.

With Microsoft Graph, you can access Office 365 data and more, from solutions across mobile, web, and desktop platforms. So whether you're building web applications by using .NET, PHP, Java, Python, or Ruby on Rails, or creating apps for the Universal Windows Platform (UWP), iOS, Android, or on another device platform, it's your choice.
