HCI Connecting to a SOAP Websevice

Hi

I've developed a very simple interface in HCI. It uses the SOAP adapter and then a Groovy script that writes the payload to the log. I'm using SoapUI to simulate a SOAP sender. I'm getting the endpoint URL from the Manage Integration Content tile - see attached screenshot. I'm using Role Based Authentication and I'm using my HCI user ID to connect in SoapUI, but I'm getting a 403 error - see attached screen shot. How do I get permission to connect to the runtime URL?

Thanks

Jonathan
