Working on ANZ-egate payment method for WP-E-commerce plugin (which is completed and here is the link to download).
Helpful resources:
- http://getshopped.org/resources/docs/get-involved/writing-a-new-payment-gateway/
- Looking at Paypal Express Checkout and Google Checkout merchant class
There are certain issues so i strongly discourage using this plugin right now. I am busy with something else at the moment so if you are a php developer you can try and extend this plugin to make it complete.
Current status: Live, doing good.
How to install: Create a new file (plugins/wp-e-commerce/wpsc-merchants/anz-egate.merchant.php) and place this code into this file. Once saved check the Payment Method section of the WP-ECommerce and it should show options for the ANZ-Egate payment method. It should work similar to other payment methods. Create your own logo for ANZegate or download this one 
and place in plugin’s images folder and update the following image url option:
$nzshpcrt_gateways[$num]['image'] = WPSC_URL . '/images/anz-egate_checkout.jpg';
*/
$nzshpcrt_gateways[$num]['name'] = 'ANZ eGate 1.0';

Bugs fixed and tested live and working. Post bugs or improvements. Thanks.
I integrated this script on a client’s site and successfully connected with ANZ E-Gate Merchant Facility. I am however encountering some problems:
– Transactions are being double billed with ANZ?
– If incorrected card details are supplied, the user is redirected to the “transaction-results”, where a large number of PHP errors and notices appear at the beginning and ending of the page. They cite problems with Line 379 of the script. I believe the issue is that the variables “vpc_AcqResponseCode” and “vpc_TxnResponseCode” are undefined as they exist in an array and are only defined on a successful transaction?
Can you give me some clues?
Hmm. Had to abandon this project for a while. I will check once i get back to this one.
