Did it work? Did it meet the requirements?

Yes.

But it sounds like your app was more of a browser-to-server app, when people talk about REST (and/or SOAP), it's rare that they mean browser-to-server interaction but server-to-server interaction.

Thanks for the insights.

In my case, the interaction was custom_client-to-server. It was only browser-to-server if you wanted to try it out manually by typing in the URL. Not sure exactly what you mean by server-to-server... My webapp didn't care if you were acessing it from a desktop app, from a flash app in a browser, a terminal-based client running anywhere, or from another webapp.
