Multi-currency
To sell in multiple currencies, you need to use Shopify Payments in your online store and activate international sales tools.
With international sales tools, you can offer a localized experience to your international customers by displaying prices in their local currency. You can also add them by using a third-party geolocation app from the Shopify App Store to include a country selector on your storefront.
Developers setting up a custom storefront with Headless commerce can refer to the Shopify Developer Documentation to create a country selector.
