Is there any way by which I can achieve passing hardcoded endpoint value to SOAP Execute?
Or in other way, can i pass hardcoded values of Request properties?
Sorry, I misunderstood the request.
I believe you can achieve this by editing the service endpoint in the WSDL file. This may require downloading a copy of the WSDL, edit the endpoint in the file, then store it in a location the SOAP Execute snap can access - such as SLDB or local system.
Optionally, you may can send your SOAP XML payload using REST POST - which allows setting the endpoint in the snap configuration. But this option can be tedious, having to build the XML first, and defeats the benefits that the SOAP Execute provides.
