I am using interac payment transaction. And I found a transaction array,The array is
$txnArray=array('type'=>'idebit_purchase', 'order_id'=>$orderid, 'cust_id'=>'my cust id', 'amount'=>'00.05','idebit_track2'=>'5268051119993326=01121122334455000000' );
My question is what is the idebit_track2 what are the two values
Please take a look at the details of interac transaction flow here but briefly, the first step is to send a "Fund Guarantee Request" to IOP gateway (Interac). IOP directs the cardholder to an issuer of the cardholder's selection (eg. a bank). Then, a response is returned to your funded/non-funded URL. This response contains several variables, one of which is IDEBIT_TRACK2, which is the value returned by the issuer. It includes (or represents) the PAN (card number), expiry date, and transaction ID. Now, the second step is to send a purchase request to Moneris Gateway using the variables you got in the response (including idebit_track2).
