11259571 - Upload Tracking Info to Woo
Orders generated on WooCommerce and brought down via the WooCommerce Connector
can have a tracking number assigned to it in BirdDog (or the local ERP that you're working with), and then invoiced/posted; when pushed back up to Woo, the tracking number is sent as well, although you need an enhancement on the WooCommerce side to see that. See here
for a more technical explanation.
