Questions tagged [outlook-restapi]

The Outlook REST APIs include the Mail, Calendar, and Contacts APIs in Office 365.

Welcome to the outlook-restapi tag! Please use this tag to find answers, ask questions, and answer questions about using the Outlook REST APIs.

The Outlook REST APIs are comprised of three distinct APIs that provide access to users' data in Office 365:

  • Mail API: Used to manipulate mail and mail folders.
  • Calendar API: Used to manipulate events and calendars.
  • Contacts API: Used to manipulate contacts and contact folders.

Getting Started

Want to explore and play with the APIs? Check out the Office 365 OAuth Sandbox. You can quickly issue queries against your own data, or against a sandboxed environment.

The Outlook Dev Center has getting started guides in a number of different languages. Start from scratch and end with a working app that retrieves messages from the inbox.

Looking for code samples? Check out the Office Dev Center's Code Samples page. PHP, Node.js, Rails, and more!

Looking for more information, or just want to keep abreast of updates to the APIs? Follow the Outlook REST APIs team's blog.
