Sale Method
Initiates an Sale transaction (authorization and capture).
Syntax
retail.sale([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
Sends a basic sale transaction to the Gateway. This transaction decrements the cardholder's open-to-buy funds for the TransactionAmount, and the transaction is automatically added to the current open batch.
