There is no standard method/data fields for adding Tracking and Carrier information within WooCommerce but Marketplaces such as eBay require this information.
As there is no standard method in WooCommerce, our solution relies on the Order Notes field. As a first step, you will need to ensure your shipping plugin adds a note such as the example below to the Order Notes field in WooCommerce when the order is marked as shipped:
Order Note Example:
This order has been shipped with: Fastway. The Tracking Number is: QB000165979. The Url is: http://www.fastway.com.au/courier-services/track-your-parcel?l=QB000165979
From this information, we can identify that the Carrier is Fastway and a Tracking Number and then provide it to the marketplace. We will then be able to add new shipping providers as the need arises; if you are missing shipping carrier and tracking number on shipped orders, and you definitely have an order note similar to the one above, please raise a support ticket with us to see if we can add your carrier.
