Hello jcreel,
Thanks for contributing to our forum. It sounds like you have selected the checkbox for "Use eBay's domestic shipping rate table" in the Shipping Tools section of your listing, but you may not have configured those shipping tables in your eBay account first. You can click the following link to eBay to view information on how to properly configure your eBay shipping rates tables. Once you have done this, you should no longer encounter that API error when posting your listings to eBay with that option selected for them.
