There are a few steps to take in order to link Facebook to your Shopify channel. First, you will need to create a Facebook Page for your business, if you haven't already. Once you have created your Facebook Page, you can then add a Shopify Shop tab. To do this, go to your Facebook Page, click on the "Add a Tab" link, and then select "Shop."
Once you've added the Shop tab to your Facebook Page, you will then need to connect your Shopify account to Facebook. To do this, go to your Shopify Admin, and under the "Preferences" section, click on the "Connect to Facebook" button.
Once you have connected your Shopify account to Facebook, you will then need to select which Face book Page you want to connect to your shop. To do this, go to your Shopify Admin, and under the "Sales Channels" section, click on the "Edit" link next to the Facebook Page that you want to connect to your shop.
Finally, you will need to add your products to your Facebook Page. To do this, go to your Shopify Admin, and under the "Products" section, click on the "Export" button. This will allow you to export your products as a CSV file. Once you have exported your products, you can then import them into your Facebook Page.
That's it! Now you know how to link Facebook to your Shopify channel.
