Processing orders from Facebook
The orders that customers make from your Facebook Page are subject to your business's published policies, since payments for these orders are processed by the Shopify checkout.
Identifying Facebook orders
Orders placed on Facebook and synced to Shopify by using Facebook Shop appear on the Orders page in Shopify. Orders appear about one hour after they are placed.
From your Shopify admin, go to Orders.
Open the Filter orders drop-down menu.
Choose Sales channel and Facebook Shop.
Click Add filter.
From the Orders page, click the order number of the order you want to view.
