Want to invoke PrivacyIDEA API via KeyCloak APIs

Configuring the server
1

Hi,
I am using privacyIdea plugin in keycloak.
Setup is as follow

  1. I have setup browser Authentication flow and have used PrivacyIDEA plugin in it.
  2. User is already enrolled in PrivacyIDEA
    3 Configured Custom Browser Flow with PrivacyIDEA settings. (This works fine when I use keycloak login page)

Requirement : I do not want to use keycloak login page instead would like to use keycloak APIs to validate a user. User will be validated in keycloak however passcode needs to be validated via privacyidea. How should I do this ? Any pointers or reference that explains the flow step by step would be of great help.

Thanks,
Dinesh
