Sorry for the delay in this query, currently we do not have this feature implemented, but it sounds we should, so if you can submit a feature request asking for it we are going to be more than glad to take it in count,
We are hitting the same roadblock trying to transition to Veeqo from ShipRush, but we need to be able to build a flow to import tracking and shipping cost to our ERP system because there is no native integration. The actual shipping cost paid is a vital piece of info for our accounting team. Is this on the roadmap to expose in the API anytime soon?
