Device ID

The terminal number will be returned in the Device ID element of the EFTLink login response (if the WorldPay software is running at the point of login) and with each card payment response thereafter. An example login response is provided below.

<ServiceResponse RequestType="Login" ApplicationSender="POSSIM" WorkstationID="1" RequestID="2" OverallResult="Success">
  <Terminal DeviceID="12345678" />
</ServiceResponse>

Note:

The Terminal Device ID should be the pertinent one for the terminal being connected.
