Hey,
I work for a company creating pickup points for goods bought online.
I am trying to create an app where customers in the checkout section can choose another delivery option. When pressing this it should show different pickup locations. The pickup locations vary based on days since these pickup points can become full or might not be open on certain dates. We have already created an Api for this so i just have to fire it and show the info. This app needs to be able to install in various shopify stores. Hope it makes sense.
I am quite new to shopify and after much reading, i am still confused on how you tackle this problem.
Thanks in advance
