information on an https REST service (with SoapUI 5.2.1)

I am very new to SoapUI and have a very simple question. In fact this is literally my third day touching it, so please bear with me. My organization has standardized on SoapUI 5.2.1 with no plans to upgrade soon.

My problem is I need to test information on an https REST service and I do not know how to get it. I have the authentication token but where do I input it?
