Hi, I'm currently building a Shopify app which is supposed to offer upsell products on cart & checkout page.
But I also want to add upsell products on the Shopify's thank you page. I thought it was impossible.
But I just read a new article related to Post-purchase upsells within Shopify checkout.
But where is the endpoints I can use in my app? Unfortunately, I couldn't find any clue. Is this just beta version?
And this is only allowed and perks for the companys like Zipify, Recharge or bold?
They seemed to already implemented this new feature, that means, it's definitely possible for all shopify developers!
Please help me understand it correctly! and how to use it!
