The Shopify APIs (REST/GraphQL) return all amounts that are part of an order as "money" objects in both the shop currency and the presentment currency.

We would prefer to maintain the details according to the currency a customer is transacting with us in, i.e. the presentment currency, rather than the conversion. The customer should receive shipping or customs documentation that reflects the currency they purchased in.
