How do I create a shopify checkout page? Is the frontpage function?I've looked through the documentation a lot and can't find anything. For example, this app created a new payment URL ... How does it work? What feature of shopify API is used?
Just checking, are you editing a Plus Store?
I have no store in the Plus plan. And I was able to install the app in my store. What they were able to do was create a new checkout page with the url: /a/secure
Open the url I put you in the post, and you will see the customization.
