Sends a void request.
This method sends a void request to the Vital/TSYS transaction server. If the authorization request was successful, the Code property will contain "200". Response will contain additional details about the authorization request.
Method parameters are:
|RetrievalNumber||The RetrievalNumber from the previously authorized transaction.|
|OriginalAmount||The original authorized amount.|
Minimum required properties:
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.
.NET Standard Notes
To call this method in an asynchronous manner call VoidTransactionAsync instead. When the method completes (or an error is encountered) the VoidTransactionCompleted event will fire.
