SOAP Request action

Hello everyone,

I'm doing a request in SoapUI like in the photo below and I'm trying to make the same request in a SQL Server Database Project in Visual Studio... I kind of copied the functions needed for creating the webRequest from here Client to send SOAP request and receive response but I'm kind of stuck now because of the action. What do I need to write for the action? In my case there is a php, I'm a bit confused. I've tried couple of things but the response remains the same.. ( -1 )

The SoapUI request

There is this WS-A panel with some info as well about the request

Also, here is my envolope for the request... just in case

I appreciate your time spent, thank you!
