Reversal - emvreverse

This section describes the message parameters for EMV Card Reversal transaction processing, which you can submit using the XML API integration method. Refer to the Integration Methods section for more information.

The emvreverse transaction reverses an approved authorization from an emvchipsale transaction after a decline by card  is received from the Chip card. The Chip card may decline the transaction data even after an Issuer approval, in this case a reversal must be sent to restore the funds back to the card. This action can be performed within 5 minutes after an emvchipsale transaction.
