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 setResponsePreviousBalance([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.message

Remarks

Balance before this transaction started. This property contains the available balance on the card BEFORE this transaction took place. For instance, if a Stored Value card contains funds in the amount of $50.00, and the TransactionAmount for this authorization was "20.00", the ResponseBalance will contain "30.00" and the ResponsePreviousBalance, if returned, will contain "50.00". This property may or may not be returned by the processor, and is not required to be printed on the customer's receipt.

This property is read-only.
