 > 💡 To obtain a refresh token, make sure your Auth0 application has the **refresh token** [grant enabled](https://auth0.com/docs/get-started/applications/update-grant-types). If you are also specifying an audience value, make sure that the corresponding Auth0 API has the **Allow Offline Access** [setting enabled](https://auth0.com/docs/get-started/apis/api-settings#access-settings).
 
+### Custom Token Exchange
+
+[Custom Token Exchange](https://auth0.com/docs/authenticate/custom-token-exchange) allows you to enable applications to exchange their existing tokens for Auth0 tokens when calling the /oauth/token endpoint. This is useful for advanced integration use cases, such as:
+- Integrate an external identity provider 
+- Migrate to Auth0
+
+> **Note:** This feature is currently available in [Early Access](https://auth0.com/docs/troubleshoot/product-lifecycle/product-release-stages#early-access). Please reach out to Auth0 support to enable it for your tenant.

 ### Errors
 
 The Authentication API client will only throw `ApiException` exceptions. You can find more information in the `details` property of the exception. Check the [API documentation](https://pub.dev/documentation/auth0_flutter_platform_interface/latest/auth0_flutter_platform_interface/ApiException-class.html) to learn more about the available `ApiException` properties.
