Payments API improvements
January 20th, 2026
In the payments API, we have introduced a new exchangeRateBatchId field. 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.
In the Create a payment (POST /v3/payments) and Create a bulk payment (POST /v3/payments/bulk) API request, you can now set the exchangeRateBatchId field that is required for paying international vendors.
Get the current BILL exchange rate and exchange rate batch ID with GET /v3/payments/exchange-rate or POST /v3/payments/exchange-rate (for multiple international vendors).
See POST /v3/payments in the API reference for more information.
