Tip Adjust

This section describes how to process a tip adjust. This is a required follow-on transaction after processing a sale with on-receipt tipping. The tip adjust request must be sent within 24 hours in order to capture the transaction.

After the original sale transaction is pre-authorized, the customer writes the tip or total amount on the printed receipt. The tip adjust request must be submitted with the tip amount or with

0

, if no tip was provided. The tip adjust amount is limited to 20% of the original transaction amount. Requests for higher amounts will be rejected. A follow-on tip adjust request is then sent to capture the additional tip amount. This transaction is also called an

overcapture

.
