Thanks for the responses.  Got a little more info; where the current 
GSoap implementation is done to the vendor software running on a local 
server; the new one is cloud (O frabjous day! Callooh! Callay!) so the 
connection is done to a public server with no reasonable option to set 
up a test account so we can create the software to talk to it on VMS.

I may find something that can run as a generic server on one of the 
customer's pc servers so we can test doing 'generic' restful but we'll 
see. More likely we'll end up with some middleware on a local pc server 
talking to the vendor cloud, and relaying requests from VMS.
