APS Proof of Concept

We need to create a basic APS application ([login to view URL]) that will make calls to our existing API. What I need is a very basic example of an APS application follows the following requirements: - Can take input. - Make a call to our existing external API with that input. Once we have this, we can move on with building the out actual production application. We need someone who is experienced in creating and deploying APS applications. If you do not have previous experience please do not apply. Thanks, Matt
