Facebook spent a lot of effort pushing marketers and site owners to implement FB Conversion API. If you run advertising on Facebook, you’ve likely already heard about Facebook conversion API and why it’s essential to implement it to make your tracking more accurate because of iOS 14, AdBlockers, and ITP. So how can you implement it? In this guide, I want to show you how to set up a Facebook conversion API for Shopify using the Google Tag Manager Server container. This method allows setting up server-side tracking using GTM web, server container, and GA4 or Data Tags to send data from web to server. The main benefit of this method is that it works for the customized websites or non-standard events where the Native Facebook app is not helpful.
Shopify allows changing “transportUrl” in GA settings. It means that you can set up a Google Tag Manager Server container on Shopify instead of a GTM Web container. I hope that this will help you solve all your tracking problems.
