Facebook pixels feed tracking information from your site into Facebook.
The feature bears some similarities to Google Analytics but typically gives you more information about the behaviour of individuals and more detailed demographics.
The basic pixel gives information about page views. It can be extended with event tracking.
This addon implements the basic pixel and purchase event tracking with no code changes required.
Compatible with any osCommerce 2.3 version including 2.3.4BS Gold and Edge.
Compatible with stores implementing multiple currencies with different formats.
