Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getLastRetrievalNumber([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setLastRetrievalNumber([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

When sending a transaction with the InteracTransactionType set to ittVoidSale or ittVoidReturn, this property must contain the ResponseRetrievalNumber from the very last transaction that you sent to the Paymentech Server. RetrievalNumberToVoid should be set with the ResponseRetrievalNumber of the transaction you wish to void.
