# Authentication

The Canva REST APIs for managing OAuth tokens.

The `oauth` endpoints enable you to generate, refresh, introspect, and revoke access tokens for your app. The endpoints implement the OAuth 2.0 Authorization Code flow with Proof Key for Code Exchange (PKCE). For more information, see [Authentication](https://www.canva.dev/docs/apps/rest-apis/authentication/).
