I sell on eBay, and I believe what I need is a link created to an external database so that I can keep track of inventory.
What I would like to do is to use a logo that reads "Click Here For Stock Status" (or something similar) that will take buyers to another page which will list the available quantity. I can provide a link that gives an idea of what I need if necessary.
I have no idea if this is the best way or what is needed to accomplish this.
Can someone please steer me in the right direction.
By the way, data feeds are available (I guess this is important.)
