Office 365 APIs platform overview

Applies to: Office 365


Office 365 API functionality is also available through Microsoft Graph, a unified API that includes APIs from other Microsoft services such as Outlook, OneDrive, OneNote, Planner, and Office Graph, accessible through a single endpoint and with a single access token. We recommend using Microsoft Graph in your apps when possible.

Whether you want to incorporate the richness of Office 365 data into your app, or create a custom experience within Office 365 itself, or use custom reports to keep your Office 365 Enterprise environment running smoothly, you can use the following developer features to achieve your goals.

Office 365 APIs

Integrate Office 365 data into your own apps

You can create custom solutions that access and interact with all the richness of a user’s Office 365 data—and you can build those solutions across all mobile, web, and desktop platforms. The new Office 365 APIs enable you to provide access to Office 365 data, including their mail, calendars, contacts, files, and folders. All right from within your app itself.

Whether you're building web applications using .NET, PHP, Java, Python, or Ruby on Rails, or creating apps for Windows 8, Universal Apps, iOS, Android, or on another device platform. It's your choice.

Office 365 APIs

Create custom experiences within Office 365

Now, you can extend Office 365 itself. Customize how your data and experiences are displayed within and interact with Office 365 to provide a seamless user experience.

  • Create a FileHandler add-in to control how Office 365 displays and interacts with your custom file types, including custom file type icons, file preview within the Office 365 UI, creating and opening the file type in a custom editor. And since FileHandler add-ins host their data and logic remotely, you can develop your add-in using the language, tools, and web development stack of your choice.
  • Add your app to the app launcher to give it visibility and make it accessible right from the Office 365 home page. Take advantage of Azure AD single sign-on to provide seamless access to your app for authorized users.

Analyze and manage the health of your Office 365 Enterprise environment

Office 365 Enterprise provides administrators a variety of developer features to keep their domains and subscriptions effective and well-tuned.

  • Access the Reporting web service to build reporting dashboards, charts, and graphs to help their organization manage their subscription usage.
  • Use the Office 365 Service Communications API (preview) to retrieve real-time service health information and Message Center communications for the domains that they own or manage. This enables them to monitor service health, manage communications, and develop plans to respond to upcoming service maintenance.
  • Use the Office 365 Management Activity API (preview) to retrieve information about various user, admin, system, and policy actions and events from Office 365 and Azure AD activity logs. Use this information to build solutions that provide monitoring, analysis, and data visualizations.

You can also create custom experiences within the Office clients, such as Word, Excel, and PowerPoint, and within SharePoint 2013 and SharePoint Online. To learn more, see Office add-ins and SharePoint add-ins.
