Credit Method

Credits a customer's card.

Syntax

retail.credit([callback])

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 this 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

This method credits a customer's card specified via Card. This type of transaction is NOT based on previous transaction. Some gateways refer to these as "Open" or "Blind" Credits.

TransactionAmount is used to specify the amount you wish to return to the customer's card.

Please see the gateway information in the table of contents to determine if your gateway supports Credit transactions.
