Bypass keycloak login system with rest api using java and generate realm/application URL

Question

I am trying to integrate apiman in my project. I am able to do following things with simple java program ( REST api ),

1. Create user for keycloak realm
2. Assign role for user.
3. Able to login in apiman with those credentials.

Things I am not being able to do ,

1. Authenticate user with rest api like keycloak does it from UI ( like the following image )
2. Generate session details and then generate URL for that realm and redirect to that project.
3. Not able able to directly login into the apiman system.

Basically I want to bypass keycloak login system with REST API using java.

I want to directly go into this screen. I am not able to find any way by which I can generate or authenticate user in keycloak and generate url for the below screen ( apiman ) and then redirect the user on the below screen using that URL.

Answer 1

I am first experience the ApiMan. But it works this URL.

http://localhost:8080/apimanui/api-manager/

It turns to ApiMan Login screen.

Then I enter new user id and password

It goes to this screen.

I follow ApiMan's steps. http://www.apiman.io/latest/download.html
