SOAP WebService to initialize a process

Hello,

I am primarily a .NET developer and have been asked to help the team with leveraging Peoplesoft WebServices. We discovered a WebService called "PROCESS_INITIATION" and I am trying to initiate a process with it, but there is no response back from the WebService after the call is made. However, process are being queued up and run, so this is a partial success already. We want to use this call to initiate a GL Process.

As a .NET developer, the IDE I am using is Visual Studio (2019) which has a code generator to consume WSDL. The problem I am facing however is that there are essentially three code generators (I think) for SOAP WSDL consumption.
