How to Set Up Facebook Conversion API on Shopify: 2025 Detailed Guide

Privacy-focused browsers and ad blockers technologies are creating a tricky situation for Shopify brands trying to collect customer data. Because the browsers will block Facebook pixel. It's hard now to have an identity resolution. So you may find your conversion data in Facebook ads manager is not accurate.

You will start to feel the impact of your campaigns with inaccurate conversion data which is not good for optimization.

With the introduction of iOS14.5, Store owners will now need to obtain explicit permission from their customers before collecting any data for advertising purposes. This has caused a significant change in the way Shopify stores can track and measure performance, as well as its effects on Facebook Ads campaigns.

To help store owners remain compliant with Apple’s privacy policy, you'll need to set up Facebook Conversion API for all events tracking. This method is more secure and reliable than using client-side (browser-side)pixels because it relies on server-side tracking instead of browser-based tracking which can be blocked or disabled by users. Setting up this tool correctly can help ensure that your store’s data is properly tracked and reported to Facebook Ads Manager so you can continue to measure and optimize the performance of your campaigns.

The Conversions API enables you to connect key events from your server to Facebook. With a recent update to iOS 15, CAPI also became a Facebook solution addressing data security threats.

CAPI or Server-Side API (SSAPI) was implemented in response to changes in how email and web-based marketing receive and process information about conversion. It provides a secure way for Shopify stores to send conversions and in-app events data directly to Facebook Ads Manager from their servers. This ensures that any data passed on is accurate, valid, and up-to-date, eliminating the need for manual tracking or pixel implementation.

Conversion API consists of the creation and use of an API that provides a direct and reliable connection between the data of the marketing system.

Almost all Shopify stores advertise in Facebook-based advertisements. Facebook's conversion API serves the exact same purpose as Facebook Pixels, though it works totally differently. Facebook pixel tracking uses the client-side and FB CAPI uses servers. Facebook CAPI allows Tracking events of websites and gathering the user information from their names and last names, etc. Creating audiences or groups of audiences from data is possible. Facebook encourages both browser and server monitoring.

Conversion API, Server-side API is similar to Facebook pixel but is much greater because you share data server-side with the server directly with you. These conversion tracking methods are more flexible due to their use of pixels and can also capture the interaction of the website.

Good quality data has a direct impact on your ads performance. Facebook conversion API can help drive better ROI from ads since it provides accurate, up-to-date information on user activity and behaviour that helps Facebook's machine learning to find target audiences faster.

1. Use the Conversions API in addition to the Meta Pixel, and share the same events using both tools

This way, you can continue to track conversions that are not shared by browser pixel and vice-versa. It's highly recommended not only to share customer purchase events but also other important events including add to cart and checkout process.

Also, make sure to use the same parameters for each event in both the Conversions API and Pixel events. Finally, make sure to keep your event names consistent with the official Facebook Event names. For example: “AddToCart” should be used instead of “AddedToCart” or “add_to_cart”. These best practices will help ensure data accuracy and consistency in your reporting.

The more events that have customer information parameters, and the more customer information parameters each event has, the more likely an event will be matched. you may collect more first party data such as customer personal information to help Facebook better identify customers.

4. Share your conversion events in real-time or as close to real time as possible.
