Initiating a payment
Send a request from your system to the API. The terminal then prompts the shopper to present their card and complete the payment. This uses the same endpoint as the Create Payment request.In the Create Payment request, set the “type” field to “POS”.
To select which terminal processes the transaction, provide its serial number in the
terminalSerialNumber field. You can find the serial number on the device under the settings menu.BYRD201 and the object includes a transactionId value you need in subsequent calls to query the transaction.
