- This transaction type will handle PreAuth CP and CNP. For CNP transactions, the Card number can be entered on the PED.
- The topuptoken returned in the response can be used to increase the amount authorized at a later time. Submit the value in the field topuptoken in a new PreAuth request and the new amount specified will be added to the total pre-authorized amount. This functionality is currently only limited to some Visa/Mastercard issuers. If the issuer doesn't support top ups, the transaction will decline.
