Slightly complex issue, but something others might want to do in the future.
We want to offer customers a bonus when they make a purchase. That bonus is access to a folder filled with content they can use with the physical items they purchased. (Example: buy a set of colored gel pens and get access to a folder of adult coloring book pages.)
Part of the appeal is that we tell customers we will continue to upload new content over time so they have a reason to return to our shop/brand regularly.
I am brand new and read that Fetchapp seems to handle single files fine with Shopify, but what do I need to do to offer customers access to a folder not a single file and how do I allow them access to any future files in the folder that were not there when they purchased?
