I want to use the Storefront API to create a custom experience and sell my products on my own custom website.
I want to sell items in different currencies at fixed rates.
e.g. a digital download that appears as $10 USD for US customers and £7 GBP for customers in the UK.
I don't want realtime currency conversion. As long as my settings in Shopify allow multi-currency am I able to use the Storefront API, creating a private app and selling in multi-currency like the example above?
