# Authentication API Support

You can use the PingFederate authentication API to integrate the Entrust IdP Adapter into your application.

The PingFederate Authentication API provides access to the current state of the authentication flow as a user steps through the PingFederate authentication policy. For more information, see [PingFederate authentication API](https://docs.pingidentity.com/pingfederate/latest/developers_reference_guide/pf_authentication_api.html) in the PingFederate documentation. To integrate the Entrust IdP Adapter into your authentication flow, configure your application based on the states, actions, and models available in the PingFederate Authentication API Explorer. For help, see [Exploring the Authentication API](https://docs.pingidentity.com/pingfederate/latest/developers_reference_guide/pf_exploring_authentication_api.html) in the PingFederate documentation.
