Updated April 08, 2019 05:24:42 The script was written by a friend of mine who wrote it for an eBay auction site.
He then shared it with me.
This script is essentially a WordPress plugin for the eBay API.
I’ve written a blog post about the script in case you want to see it in action.
If you’d like to try the eBay PHP script yourself, the documentation can be found here.
