CC Via Migs - Return Receipt Handling and use of hidden form fields

I'm using the cc via migs module with ANZ eGate. It's a server hosted setup.

I've got it handling the transactions ok but there are a couple of things that don't meet anz's requirements. It's possible they've changed their requirements since the module was created.

Each receipt page, including unsuccessful transaction must display a receipt number. We require both the Return Receipt Number (RRN) and the OrderInfo field (as long as it's unique to the cardholder's transaction) to be displayed.

Here are the two issues:

1. We require the receipt page displays the out come of the transaction, the below transactions must its matching result on the receipt page.

2. The Merchant ID is displayed, Therefore all transactional information should not be passed through the browser in a way that could potentially be modified (e.g. hidden form fields). Transaction data should only be accepted once from a browser at the point of input, and then kept in a way that does not allow others to modify it (e.g. database, server session, etc.)

Has anyone had similar issues? Were you able to resolve them?

Hi tjjjohnson,
I am also trying to integrate CC Via migs into Zen cat and are having the same issues. I have written some code that passes the transaction response code back to my website to display each error e.g. card declined and was wondering if you have had an luck with question 2. in your post?

Cheers.

@magikmoose I did solve the issue with the hidden form fields. I've attached my modified version of cc_via_migs.php. I don't recommend copying the whole file though as there are other modifications.

Look at the code to see the changes.

In process_button()
Stop "drawing" the hidden form fields

In before_process()
Pass info in _POST

It's been a while so there could be some other changes I've forgotten about. Hope this helps.

Thank you soooo much!! I have spent countless hours trying to find my way through this. I will take a look now. Thanks!!!!!!

Sorry here is the file I forgot to attach.

@ tjjjohnson

What is your overall experience with this mod? I posted **this question** about a year ago and had no feedback.

Thanks

This file does create a receipt as below in email
Payment Method
Credit Card (online via ANZ eGate)
You have paid for your order online using ANZ eGate
Receipt No: 11**********

and within the site
Credit Card Type: AcqResponseCode: **
Credit Card Owner: TransactionNo: ****
Credit Card Number: ReceiptNo: **************

So long as the CC receipt is recorded there shouldn't be an issue and the actual detail you need is all held with the CC manager

@ozprodrivers

It was easy enough to get it installed and handling payments.

The trouble was it did meet the ANZ eGate requirements and failed the review that is done before going live. This was due to two things

1. insufficient error reporting - had to add code to pickup the error codes and display the required messages.
2. use of hidden forms for passing information - I changed this to pass the info in the _POST variable.

You should have an easier time making the changes if you look at the file attached above.

Once that was done everything works quite nicely and provides a pretty good user experience.

Thanks for that I am unaware that there is a change with ANZ requirements and they certainly have not sent anything to us or anyone I know using the MIGS system.
We are going to look at this module soon as it will have to meet PCI specifications whether it is enforced here or not
We are going down the track to ensure our site and dedicated server we operate is all PCI compliant, so maybe this is part of the equation

Hi,

i'm using tjjjohnson's modification installed on zen cart 1.3.7d and am down to one issue.

Within the banking site, cancellation of a transaction results in the user being taken back to the banking site's first page, and not back to our site as should be.

Does anyone know why this would be and where it might be changed?

All other transaction results go back to the payment page with correct error reporting or the checkout success page accordingly.

Best regards, Bryan

and thanks for all the work that went into this mod!

Hi all,

i found a cancellation return issue, and an intval rounding issue and fixed them.

Maybe the bank have changed their side of things recently.

Let me know if anyone has any similar issues and i'll post the code here.

Cheers, Bryan

Hi Bryan,

Could you post your modified file so I can take a look at the changes.

Another issue I'm having (using zen cart 1.3.9h and MIGS bank hosted module) is that the zen session times out if a customer enters incorrect credit card details in MIGS, then re-enters the correct details. This results in the payment being made but no order details in zen cart.

One of my clients has been trying to get around this by matching the customer's IP and then using 'recover cart sales' to see what their customer ordered. The problem is that the customer's IP address is not always recorded.

If I could get the MIGS module to pass the customer ID or customer name on to the MIGS receipt, at least that would be a temporary solution to the session time out problem.

Does anyone know how to pass the zen customer ID variable to the MIGS site?

Cheers,
Luke

We are having the same problem with 1.5.0

I posted a job on UpWork https://www.upwork.com/jobs/_~016e51e754d3d30cfe
I could try but better to find someone with previous experience if possible
