There a a number of possible approaches, I don’t know which would be best for your situation. They all start by going to the Meta Events Manager through your Facebook account. For more information see:

The end result will be placing some JavaScript code in the head section of your WP pages. There are a number of paths you can take to get here.
I recommend getting in touch with WooCommerce’s support about this via https://woocommerce.com/my-account/create-a-ticket/ if you have any of their paid WooCommerce products or https://ww.wp.xz.cn/support/plugin/woocommerce/ if you do not.
