AuthOnly Method
Initiates an authorization-only request transaction.
Syntax
icharge.authOnly([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 sends an authorization-only request to the specified Gateway. This transaction is not added to the current open batch, and must be completed later with the Capture method (you may use the Sale method if you wish to authorize and capture in one step).
Note: If the Gateway does not support this method, the class will fails with an error.
