I first started with Foxycart some time ago and set it up for my site using FoxyShop.
At the time I set up the XML Datafeed and today realized still I don't know the purpose or if I even need it. I sometimes get XML Datafeed errors, and got two recently on the site (www.naturalglowsunless.com). So I go in and "refeed" them and it seems fine.
But in dummy terms -- what is that doing? Is it a means to send customer info from a transaction to a 3rd party program?
Also if I don't have a need for it, can I just turn it off with no problem?
