Get started with Office 365 APIs powered by Microsoft Graph
Let’s build a simple app that connects to Office 365 data using the Microsoft Graph. This API enables your website or mobile app to connect to a user’s mail, calendar, contacts, files and more data from Office 365 -- all through a single endpoint.

Response Body
Pick the platform you'll be building for
Let’s build a simple app that connects to Office 365 and calls the Graph API. Pick your platform, and we'll walk you through getting the right tools, registering your app, and running the code.
Note: You can not change the platform once an app has been registered, to change the platform, please refresh the page and start over.
Register the sample app
To get started, we'll register a sample app to securely access Office 365 data using the Microsoft Graph. We'll get you the sample app in a bit, but to make things easy, let's register first. The sample app only supports the Mail.Send permission. To register a new application with more permission options, such as Users, Calendar, Contacts and Files, learn how to Register a new application.
Start coding
Download our code sample to get going. If you signed in and registered your app, we'll embed your Client ID and everything else you need in the package for you.
