This is a rework of the Dynamic Target creation tap I made but using the Web HTTP request instead of the Execute Web Activity. This will make the web executes much faster and not run into WSDL discovery issues.
I have *not* tested this directly in these processes but have tested all the web calls via SOAP UI.
I made this since I needed to switch to using web http requests instead of the execute web in one of my projects.
It is a community tap so hack away.
