What is App URL while creating the shopify App

Hi,

We are developing an integration for Shopify with our SaaS based feedback app and also wish to publish the app in the Shopify App Marketplace. We are currently done with the integration and now are ready to publish. My question is what regarding the field. My understanding is that this URL is hit when the user clicks on the Install App button post the oAuth process. But I am

not able to figure What this URL should be and what process should be followed to create this URL and where should it be hosted. Any guidance on this will be appreciated.

To tell more about the integration:

  1. There is no code or feature implemented on Shopify, its purely on our app end.

  2. We just make use of their Events webhook and listen to them to make our integration work
