New code for unrecognized currencies
API
Effective June 30, 2021
As of API version 2021-07, the GraphQL Admin API returns XXX in response to an unrecognized currency code. XXX is the ISO code used to denote transactions that involve no currency.
In mutations, a CurrencyCode input value of XXX is invalid. XXX can only be returned as a result and not as an input value.
This change prevents order pages from breaking if payments include a currency code that's not in the list of [supported values for the CurrencyCode object](api/admin/reference/common-objects/currencycode).
