currencyCode property
The currency in which the billing account is billed and charged,
represented as an ISO 4217 code such as USD.
Billing account currency is determined at the time of billing account creation and cannot be updated subsequently, so this field should not be set on update requests. In addition, a subaccount always matches the currency of its parent billing account, so this field should not be set on subaccount creation requests. Clients can read this field to determine the currency of an existing billing account.
Optional.
