Create a Facebook pixel and have it added to your site; you can select the “Send to Developer” option and forward the script to firstname.lastname@example.org.
Create a product catalog in Facebook under Commerce Manager in Business Manager.
Find your product data feed within SiteManager. Login, go to Integrations, and copy the link that says “Facebook Catalog Feed.”
Use the product data feed to add your products. Under your catalog you just created go to Data Sources > Add Items > Use Bulk Upload. This is where you can paste the product data feed URL. I recommend to schedule this to update nightly so all of your product changes, price updates, etc. will be pushed through.
That’s it! You can now use this catalog to run products ads, tag items in Instagram (if you set up Instagram shopping), and/or set up a Facebook shop.
