I am migrating a Liquid site to a new headless storefront. The site currently includes the Shop Pay “Pay in X interest free installments of $X with Shop Pay [Learn more]” messaging:
However, something you could do as a “hack”, is that you could create this feature using Javascript, and have the “four payments” just be whatever the cost of the product is divided by 4, then show that value on the HTML. That would mean either pulling the product’s value from a backend, a local storage value, or an “ID”.
