Registering your app for Microsoft Graph

To use the OneDrive from the Microsoft Graph, you need to first register your app and receive an Application ID to represent your application in API calls.

For most applications, we recommend using the Azure App registrations page. However, for some enterprise-class applications, your app may need features that are only available via the Azure Active Directory management portal. If you are unsure about which approach to use, see Deciding between Azure AD and Azure AD v2.0 endpoints.

Register your app with Microsoft

To connect with Microsoft Graph, you'll need a work/school account or a Microsoft account.

1. Go to the Azure App registrations page.
2. When prompted, sign in with your account credentials.
3. Find My applications and click Add an app.
4. Enter your app's name and click Create application.

After you've completed these steps, an application ID is created for your app and displayed on your new app's properties page.

If your application is a confidential client (a service), you must create a new app password to secure your application. For public client apps (native apps or JavaScript apps), you do not need to an app password.

Important Treat the value of any app password the same as you would a user's password. The secret represents the key to your application and, if made available, can be used to impersonate your application.

Under the Platforms header, configure details about your app. By default a new app is created as a web app and needs one or more redirect URIs. To enable native client flows for your app as well, click the Add Platform button and choose Mobile.

Microsoft account uses scopes to determine which API your app can access, and these scopes are included in the OAuth flow when the user logs in. For more information about how to authenticate a user with your app, see OneDrive authentication and sign-in.
