# Authentication API support

You can use the PingFederate authentication API to integrate the Microsoft 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. Learn more in [PingFederate authentication API](https://docs.pingidentity.com/pingfederate/latest/developers_reference_guide/pf_authentication_api.html) in the PingFederate documentation.

To integrate the Microsoft IdP Adapter into your authentication flow, configure your application based on the states, actions, and models available in the PingFederate Authentication API Explorer. You can find help in [Exploring the Authentication API](https://docs.pingidentity.com/pingfederate/latest/developers_reference_guide/pf_exploring_authentication_api.html) in the PingFederate documentation.
