As you probably know, you can sell products created with the TPOP application on your Facebook page.
Facebook offers a shop section, the application allows you to insert your products very easily.
This tutorial is compatible with the standard Shopify package, as well as the Lite package.
Activate sales channels
If you have not yet activated Facebook and Messenger in the sales channels (the places where you want to sell), you can easily do so:
Next you need to link your Facebook account to your Shopify account:
Click on "Account" under the Facebook tab on the left hand side of the screen then "Connect an account", then choose your page from the drop down menu.
Your page is now associated.
Now, to select the products you want to sell via Facebook, go to a product sheet, then in the "Sales channels" box select "Manage". Check the appropriate box(es) and in a few minutes your products will be automatically added to your page under the "Shop" tab of your Facebook page.
Note that the process is the same for Messenger.
Easy, isn't it?
