Directory API: Authorize Requests

Every request your application sends to the Admin SDK API must include an authorization token. The token also identifies your application to Google.

About authorization protocols

Your application must use OAuth 2.0 to authorize requests. No other authorization protocols are supported. If your application uses Sign In With Google, some aspects of authorization are handled for you.

Authorizing requests with OAuth 2.0

All requests to the Admin SDK API must be authorized by an authenticated user.

The details of the authorization process, or "flow," for OAuth 2.0 vary somewhat depending on what kind of application you're writing. The following general process applies to all application types:

1. When you create your application, you register it using the Google API Console. Google then provides information you'll need later, such as a client ID and a client secret.
2. Activate the Admin SDK API in the Google API Console. (If the API isn't listed in the API Console, then skip this step.)
3. When your application needs access to user data, it asks Google for a particular scope of access.
4. Google displays a consent screen to the user, asking them to authorize your application to request some of their data.
5. If the user approves, then Google gives your application a short-lived access token.
6. Your application requests user data, attaching the access token to the request.
7. If Google determines that your request and the token are valid, it returns the requested data.

Some flows include additional steps, such as using refresh tokens to acquire new access tokens. For detailed information about flows for various types of applications, see Google's OAuth 2.0 documentation.

Here's the OAuth 2.0 scope information for the Admin SDK API:

If your public application uses scopes that permit access to certain user data, it must complete a verification process. If you see unverified app on the screen when testing your application, you must submit a verification request to remove it.

Tip: The Google APIs client libraries can handle some of the authorization process for you. They are available for a variety of programming languages; check the page with libraries and samples for more details.
