If you are using Builder’s Shopify App, and the page you have built in Builder is using product boxes, you might not have to do anything (depending on what it is exactly you are trying to do). Product boxes have built in logic to show international pricing if the product has different prices based on locale. They way it does this is by looking at the current page the customer is on to determine if they have selected a particular currency or locale, and then when querying the product box api we send that along to get the proper price. That means the product box price will always show the correct currency automatically.
If you are instead trying to list all the product prices in one list, you might need to do a specific query from the Builder page to get that data. Can you tell me more about what it is exactly you are trying to do, and provide a builder content link (e.g. builder.io/content/some-id), so I can be more specific on what APIs to use and how to do it in Builder?
Once you have created the storefront token, you can fetch data from within Builder using
Hopefully that helps!
