I sell on eBay, and I believe what I need is a link created to a supplier's external database so that I can keep track of inventory.
What I would like to do is to use a logo in my listings 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 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.)
