Trimble Business Center connection

Trimble Experts-

I am attempting to add an External Service to Trimble business center. It says that you can connect ProjectWise but gives no instruction. The values it is looking for are below. I have entered in my web server address, my user as well as the admin user, and used the defaults for the last 2 with no positive results. My main question is what are the ProjectWise requirements? Web server? Mobile Access? Something else? I'd prefer a guide if there is one. If not why not? I have looked through the documentation but haven't seen anything referencing this, and zero results in the forums. 

Thanks, Joe C.
