PieSync supported syncing ShipStation. You can keep using PieSync through 2021, but in the meantime we're checking if we need to prioritize turning this into a data sync app? Please upvote! Thanks.
This would be incredibly useful for my business, and, I imagine, any busiess with a shipping component. I'd love to be able to trigger workflows whenever a shipment is received, intercepted, or initiated. So much to be had here!!
