sorry for the delay, but we had a severe hardware problem on one of our server on monday and so we had some problem answering before.
We didn't capture tracking number from eBay, since in italy eBay didn't provide this kind of information but we work in the opposite way.
- Receive an order on eBay
- Download order in Ready Pro from eBay
- In Ready Pro create the shipping documenti / shipping invoice
- When we ship the product to the carrier they provide a tracking number that you can insert or import in the invoice in Ready Pro
- Ready Pro can send the tracking number inserted in the invoice to eBay to update the order
But i think this is the opposite of what you're talking about
Merry christmas and happy new year.
