OsCommerce Bitcoin Payment Module
From Bitcoin Wiki
There are extension modules for osCommerce to accept bitcoin as payment has been released.
- Bitcoin-Cash  payment module is implemented without further needs of installing or the Bitcoin daemon. First user is the online-shop Designers-Heaven.
-  It has since been improved to receive notifications back from the Bitcoin daemon via a Python script. The improved version also manages incoming funds, sending them offsite to reduce risk, as well as watches and restarts the Bitcoin daemon.
