I am not aware of an eCommerce module for the DPS-hosted payment page. Things you need to be aware of when accepting the credit card details directly on your own site are that you will require an SSL certificate and that certain merchant banks actually mandate that their account holders use the hosted payment page due to its ability to facilitate 3D secure transactions.
I would be interested to hear how you got on with this.
Have been integrating the standalone DPS module to SS 2.4.5 Payment 0.3.0. All is working well except in IE9. When redirecting to the gateway in IE9 we get a blank page. if we press the back button we quickly see the paymentexpress animation then the cart shows up empty.
Various versions of Safari, Firefox and even earlier versions of IE (tested with 7) work fine. Seems to be just with IE9.
Anyone have any great ideas?? esp Mr PaymentExpress :)
