The e-commerce.

Authorize.net giving a transaction failed message


Recommended Posts

Hi We have an osCommerce Setup version 2.2 MileStone 2 running perfectly fine for a couple of years now. However suddenly the CC via the authorize.net module aren't working and even for valid CCs it returns an invalid card message.

Nothing really has changed on the server except for some security settings which were needed as a part of the PCI compliance certification.


I've read through numerous posts on this forum about the authorize.net issues but none of them seem to fix our problem.


I'm even willing to pay a fee for anybody who would be able to fix it


Thanks in advance
