AuthenticationXID Property

The unique transaction identifier.

Syntax

 mpi.getAuthenticationXID([callback])

Default Value

""

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 getAuthenticationXID([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 setAuthenticationXID([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

This property will contain the Base-64 encoded TransactionId value received in the response to a Payer Authentication Request (PAReq).

Note: Some payment processors require the TransactionId (XID) be submitted in a 28-byte Base-64 encoded format. If so, the value contained within AuthenticationXID can be sent. If the value should not be sent Base-64 encoded, the value specified within TransactionId can be sent.

This property is read-only and not available at design time.
