Get the current BILL exchange rate and exchange rate batch ID for multiple international vendors with one API request. When the vendor bill currency is not USD, the exchange rate batch ID is required for creating a payment with POST /v3/payments or POST /v3/payments/bulk.
BILL maintains all exchangeRate values in a batch. When a batch expires, a new batch ID is generated and all exchangeRate values are updated in the new batch. Use this endpoint to get the current exchange rate and batch ID based on the payment amount and vendor bill currency.
When an exchange rate batch expires, you need a new batch ID for your payments API operations. The batch expiration date is tied to the processDate you can set in your international payments API request (with POST /v3/payments or POST /v3/payments/bulk).
Note: When the vendor bill currency is not USD, the payment processDate must be the next US business day.
