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. You can filter your orders to show only orders placed through Facebook in the Product status section of the Facebook sales channel.
From your Shopify admin, go to Orders.
Click More filters > Sales channel.
Select Facebook Shop.
From the Orders page, click the order number of the order you want to view.
