# Look up and reverse a bank-transfer payment in an open batch.

Look up and reverse a bank-transfer payment in an open batch.

1. OPTIONAL — list bank transfer payments matching the search filters to find the paymentId to reverse. processingTerminalId is required for this list. Skip if you already hold the paymentId.
 [listBankTransferPayments](/api/list-bank-transfer-payments)
2. Reverse (void) the bank transfer payment in the open batch. Takes the paymentId in the path and a required Idempotency-Key header; this endpoint has no request body (the amount cannot be varied here). Success returns transactionResult.status == reversal.
