How do I connect my store to inventory and shipping automatically? — answered by Engineer Saeed Baatiah
The link works in two directions: from inventory to the store, available quantities update the moment they change so nobody buys an out-of-stock item; and from the store to the courier, a waybill is created automatically on order confirmation and the tracking number reaches the customer. The point most often forgotten: handle temporary connection failures with automatic retries, or you will discover orders with no waybill days after they were placed.
