I am an experienced developer but brand new to building shopify apps. I have followed the basic tutorial to set up a shopify app using “npm init @Shopify_77 [email removed] and have created my development store to test against. I am starting to understand how to interact with my app through the admin portal but need some guidance on how to implement functionality that can respond a user’s activity within a store and dynamically make updates to the store’s html. To be more specific about my use case and what I am trying to accomplish, when a user goes to view a product I want the store to make an api call to my shopify app and then dynamically disable the ADD TO CART button based on the response that my api returns.
I would appreciate information on what the best approach to this problem would be and what tools to look into. I am not sure if the Theme App Extension is what I should be using or not.
Thanks,
Josh
