REST API

Performing a Sale with On-Receipt Tipping

This section describes how to perform a sale with on-receipt tipping and the required follow-on tip adjust. After the original transaction is authorized, the customer writes the tip or total amount on the printed receipt. A follow-on request is then sent to capture the additional tip amount. This transaction is also referred to as an overcapture
.

The original transaction is performed as a pre-authorization. A follow-on tip adjust request must be done within 24 hours in order to capture the transaction. For more information, see Performing a Tip Adjust.

WARNING

By using this feature, you assume the risk of the overcapture being declined and increased chargebacks. Only use this feature if required. The recommendation is to perform a sale with on-reader tipping whenever possible. For more information, see Performing a Sale with On-Reader Tipping.
