Since there is something to pay, there is an ECR payment. It can be made with cash, by card or whatever you accept yourself. When this is done, you need to tell the API that the payment took place, so that the card balance is used for the remainder.
The endpoint for this is POST /api/v2/Smart/Transactions/{id}/start/cash. It is always /start/cash when the merchant conducts an ECR payment without secupay.

The payment was registered, and the card credit was used.
The node /transactions holds the tranactions. There is only a Loyalty Transaction, since there is no card payment processed by secupay here.
The node /receipt holds an array of receipt lines that shall be printed by the ECR.
