First a Creator (which you can just leave at its default settings) and then the HTTPCaller. The reason we need the Creator is because the HTTPCaller needs to be triggered by a feature.
Thank you! After I posted this question, I saw an example with that and tried it and that did make the HTTPCaller run, however what I'm getting back is the HTML for the login page, so apparently the authentication I'm using isn't correct. I know the login and password work, but I may need to authenticate in a different way. When logging in manually, I can get to a download link, however their online service may not support the authentication methods in the HTTPCaller.

Looks like MoveIT file transfer does have an API, so am looking through their rest documentation to do the authentication.
