Is server-side tracking really necessary for a Shopify store?
I run a Shopify store and currently use the standard pixel + maximum data sharing option from Shopify. Lately, I’ve been hearing a lot about server-side tracking setups (using Stape, CAPI Gateway, sGTM, etc.).
For those of you running e-commerce stores: • Is server-side tracking actually necessary or more of a nice-to-have? • Have you seen real improvements in ad performance (better attribution, lower CAC, etc.) after switching? • Or is the default Shopify data sharing enough for most cases?
Would love to hear your experiences before I invest time and money into a setup.
The short answer is:
Server-side tracking is becoming a necessity for optimizing ad performance, not just a nice-to-have, even with Shopify’s maximum data sharing option.
That option is good, as it uses a version of the Conversions API (CAPI) for purchase events, but it is not as robust as a dedicated server-side setup for all critical events.
Dedicated server-side tracking, specifically by using the Facebook Conversions API (CAPI), captures significantly more conversion data that would otherwise be lost to ad blockers and browser restrictions like ITP.
This dramatically improves the data quality Meta receives, leading to higher Event Match Quality, which in turn allows Meta’s algorithms to optimize your ad spend more effectively, resulting in better attribution, lower Cost per Acquisition (CAC), and higher Return on Ad Spend (ROAS).
The long answer is:
The reason you are hearing so much about server-side tracking is that the environment for client-side (browser-based) tracking has changed dramatically due to privacy measures like iOS updates and ad blockers, which can block 30% or more of your conversion data.
The “maximum data sharing” setting in Shopify’s Meta integration is a good first step because it does send the Purchase event via CAPI, which is a server-side connection, alongside the pixel.
However, this native integration is often limited in the quality and richness of the data it sends for other critical events like ViewContent, AddToCart, and InitiateCheckout.
A full server-side setup complements the pixel to create a hybrid tracking environment that sends events from the browser and the server.
The CAPI-based server events bypass browser restrictions, ensure nearly 100% accuracy on critical conversions, and allow you to send richer first-party customer data (like hashed emails and phone numbers) more reliably.
This superior, complete data set is what directly translates into better ad performance because the ad platforms have a clearer picture of who converted and when, allowing their machine learning to optimize bids and delivery more precisely for your next best customer.
Case studies from merchants who have implemented server-side tracking often show a measurable uplift in tracked conversions and a notable decrease in CAC.
For an excellent and relatively cheap solution, the combination of Shopify’s native data capabilities, Google Tag Manager (GTM) for server-side tagging, and a managed tagging server provider like Stape is highly recommended.
Shopify is the source of the data.
You can configure a Shopify webhook (e.g., for a ‘New Order’) to instantly send its purchase events and data directly to your GTM server container.
GTM then processes and routes that data to its final destination, like the Facebook Conversions API.
Running a GTM Server-Side container requires server hosting, and while you could use a cloud provider like Google Cloud Platform, the costs can be variable and the technical setup is complex.
Stape offers a simplified, fixed-cost hosting solution specifically for GTM server containers.
This combination eliminates the complexity of managing a cloud server yourself and can be significantly cheaper and more user-friendly than a custom Google Cloud Platform setup, making the power of server-side tracking accessible without needing an in-house developer.
It gives you the control and data accuracy of a dedicated server-side setup at a low monthly maintenance cost.
