REST Webservice from Workbench

Hello,

I have a simple requirement, I need to invoke a REST webservice from a workbench process, and store the output in a variable (content is XML data to render in a form).

I tried using the Invoke WebService component, but it is only allowing SOAP-based webservices.

How can I achieve this? Is my approach wrong? The idea would be to get a user input throught a human-centric process (a document id), then pass that to a WS that will marshall the XML data and the render the form based on the XML data...

Thanks for your help!
