Adding tracking code javascript to a shop via a web pixel

[yawlerman]

I have a platform that customers use to drive traffic to shops.  I'm needing to add 2 snippets of javascript to the shop.  The first pulls the affiliate code out of the url and stores it in the cookie.  The second pulls the code out of the cookies and sends info back to my app after a successful checkout.

I've tested the process on my demo shop by manually adding the first snippet to my test shop's theme.liquid file.  Then I created a custom pixel for my test shop with the second snippet.

I don't want to have to do that for every shop so I'm now trying to create an app that is simply a web pixel that will register listener events for the page_viewed & checkout_completed events.

My app has been rejected because of 3 things:

1. I don't have a screencast link showing how my app works
2. I don't have screenshots of my app
3. I don't have a functioning UI

I don't understand how my app is supposed to meet these requirements as there is no UI.  There is only the web pixel.  Below is a picture of the default page for the app that I thought would be sufficient but apparently it's not.  Any advice on how to get my app approved?  It won't be listed.  I will send it to shops that sign up as affiliate partners so they will already know what the app will do.
