An access token is an authorization string that allows access to secure content, data, and/or location services in ArcGIS Platform. Access tokens define the scope and permissions available to your application.
There are three kinds of access tokens:
- API key is a permanent token that grants your application access to ready-to-use services and, with an ArcGIS Developer account, private content (currently in beta).
- ArcGIS identity (formerly named user) grants a short-lived token, generated via OAuth 2.0, giving your application permission to access the content and services authorized to an existing ArcGIS user's account.
- Application credentials grant a short-lived token, generated via OAuth 2.0, authorizing your application to access ready-to-use services.
