Hi, I'm one of laracsac colleges. The service can be openend by typing the username and password in the URL. But that works only in the WebBrowser integrated in Pega and not when opening the WSDL in the ServiceClient. Regarding your question, it is a in-house service but we're externals and based on our experience I'm affraid that it will take some time for us to get any information.

I've an update regarding our problem. We mvar client = new System.Net.WebClient {Credentials = new System.Net.NetworkCredential(user_name, password)};

            var response1 = client.DownloadString(url);

            return response1;anaged to call our WSDL URL in Pega with a c# script
