[keycloak-user] Login page for external IDP using SAML

Hi All, I was trying to setup Keycloak to use SAML and configure an external IDP in the admin console of Keycloak. I had a couple of questions : 1. What is the keycloak API we need to hit to access the landing page for the external IDP? 2. I was trying to call the /realm/{realm-name}/broker/{provider-id}/login API The problem that I was facing when I used the above API was that it expects "code" as the Query parameter and I did not find any example on how to generate that code. Any help would be appreciated. Thanks, Robin
