Rest EndPoint

I have installed karaf+camunda and feature:repo-add mvn:org.camunda.bpm.extension.osgi/camunda-bpm-karaf-feature/4.0.0/xml/features.
I’m not sure, but with above features I’m able to invoke rest service of camunda.
I don’t know how to configure HTTP port of rest service.
Please. Help me.
Regards
Antonio
