Reverse Method

Performs a reversal transaction.

Syntax

Remarks

This method sends a reversal request to the Vital/TSYS transaction server. If the authorization request was successful, the ResponseCode property will contain "200". Response will contain additional details about the authorization request.

Minimum required properties:

• GenKey
• MerchantId
• RoutingId
• RetrievalNumber
• TransactionAmount
• TransactionType

Note either RetrievalNumber or TransactionNumber may be used to reference the transaction that is to be retrieved, adjusted or voided. If both are supplied, the RetrievalNumber will be used and the TransactionNumber ignored.

In the case of performing level 3 or settlement transactions, TransactionNumber is not supported and thus RetrievalNumber must be used to reference the transaction.
