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 Authentication API in the PingFederate documentation.

To integrate the Duo Security 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 in the PingFederate documentation.
