Every time an order is created in Lazada, this order goes to Shopify through OMNA. Shopify updates its inventory and notifies OMNA of the update through a webhook. OMNA finds the product associated with the change in the inventory and update the product in Lazada. When the product inventory is updated directly in Shopify, OMNA will be notified to update Lazada's inventory accordingly. The inventory level will be updated from Shopify to Lazada in a few minutes.
