eBay's Global Shipping Program (GSP) is a service where you ship your package to eBay's facility in Kentucky and they take responsibility for delivering your package abroad. The good news is you can save even more money on shipping by using Pirate Ship to get your package to Kentucky, instead of using eBay's shipping for that portion of the delivery.
Unfortunately, eBay's API doesn't give us all the information we need to import these orders, so we can't display them in your Import page in Pirate Ship.
However, you are still able to create these labels manually in Pirate Ship. When creating the label, the GSP reference code should be put into the Company field, while the recipient's name and all the other details go in their respective fields. After buying the label, be sure to copy/paste the tracking number back to eBay to mark the order as Shipped.
