# Get authentication token that allows customer to log in or verified in other applications.

`GET /tokens/{token_id}/actions/auth-token`

This endpoint returns an authentication token. Another application that uses the CareCloud API can use this token to verify the customer or sign the customer in. Typical uses include redirecting a logged-in customer from one app to another, or completing sign-in in an in-app browser for a different application or portal.
⚠️ Endpoint is available only in Customer interface.
