Get the current BILL exchange rate and exchange rate batch ID for paying an international vendor. 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.

In production, a BILL batch is valid for a maximum of 20 minutes. response provides the timestamp when the current batch will expire. For example, if a batch has been active for 17 minutes when you get the exchangeRateBatchId, expirationTime indicates that you have 3 minutes remaining (with POST /v3/payments or POST /v3/payments/bulk).

Note:

• International vendor payment information is required for you to get the BILL exchange rate with this endpoint.
• When the vendor bill currency is not USD, the payment processDate must be the next US business day.
