Hey, I'd love to build a Shopify app like Zipify
I don't need to have all the features, but what I want to have.
1. Thank you page upsell functionality
Store owner should be able to select image and products which will be appeared on thank you page
2. Upsell feature.
Store owner should be able to select some products triggered by a parent product addtocard.
Just let me know if you have the ability to do this!
