I am looking for the "top level" reference to ALL web services available to Nintex workflows. For example, I know that if I want to, say, do something with a list item I should specify <siteURL>/_vti_bin/Lists.asmx as the URLin the web service action. I also have discovered, empirically, that I can manipulate documents in libraries with web services available through <siteURL>/_vti_vin/copy.asmx. For workflow-related operationsI can specify <siteURL>/_vti_bin/ NintexWorkflow/Workflow.asmx as the URl and then see what methods are available.
This is all great and works like a charm, but requires that I know, IN ADVANCE, the exact URL for the web services that I want to invoke. What I am asking about here is the high-level list of all web services that are AVAILABLE. That is, what else is available besides <siteURL>/_vti_bin/Lists.asmx, <siteURL>/_vti_vin/copy.asmx, and <siteURL>/_vti_bin/ NintexWorkflow/Workflow.asmx and how would I query to discover these?
