You can sell your products on Instagram by using the Instagram Shopping feature in the Facebook channel. Instagram Shopping creates a shop on your Instagram profile and lets you tag your products in posts and stories. Customers can select View Shop on your Instagram profile to view all of your products in Instagram. Customers can also click on posts to view a tagged product, and then select View on Website to make a purchase on your online store.
If a customer clicks a product listed on Instagram to view it and make a purchase, then the order is listed as referred by Instagram.
To use the Instagram Shopping feature you need to be located in a country or region that is supported by Instagram and your products need to meet the product requirements for selling on the Facebook channel.
