Facebook Conversions API (CAPI) is server-side tracking that works alongside Facebook Pixel tracking to help you improve the performance, measurement and data collection of Facebook campaigns. Facebook developed CAPI in 2021 after finding that they had been "underreporting iOS web conversions by approximately 15%"
Littledata's Facebook CAPI integration enables Shopify and BigCommerce stores to send accurate data to Facebook for better retargeting and audience building. In short, it's a direct connection from Shopify to Facebook CAPI or BigCommerce to Facebook CAPI.
Facebook Ads, covering both Facebook and Instagram networks, is the second largest paid channel for most of Littledata's customers (larger DTC brands on Shopify and BigCommerce). Facebook Ads has invested heavily in machine learning to help you the right shoppers, but now more than ever these algorithms need accurate and complete data about the customer journey for them to optimize marketing spend. Simply put, better event data leads to higher return (ROAS or ROI) on investment in Facebook Ads, especially dynamic product ads.
Facebook (Meta) has put together some useful case studies about CAPI for ecommerce:

With Littledata, it's super-easy to add Facebook CAPI! If you're using Shopify, just install our Shopify app and then enable CAPI from the Connections tab in the app. If you're using BigCommerce, just install our BigCommerce app and then contact us for CAPI access.

Yes. If you are using Littledata's Shopify source for Segment you can either send data from Segment to Facebook CAPI (using Segment's Facebook CAPI destination) or send data directly from Shopify to Facebook CAPI (using Littledata's Shopify to Facebook CAPI connection) in addition to the data you send from Shopify to Segment.

Server-side Google Tag Manager (sGTM) requires customers to spin up their own tracking servers on Google Cloud. This is a complex process that requires developers for both initial launch and ongoing maintenance. In contrast, Littledata’s server-side tracking works automatically. We keep it up to date behind the scenes, handle hosting, and maintain the connection for greater consistency and lower ongoing costs. This is why thousands of top DTC brands trust Littledata as part of their modern data stack.
An added benefit is having a single source of truth with a consistent schema. Customers already using Littledata for Google Analytics will see completely consistent data, from a single source, in Facebook Ads.
Similar to how Littledata improves Google Analytics tracking by 20-30% for most stores vs. Shopify's default GA integration, our Facebook CAPI connection includes more granular detail, more accurate checkout funnel tracking, better subscription tracking, and more complete lifetime value (LTV) tracking. Littledata offers a much more reliable way to sell and market across Facebook and Instagram.
Shopify's Facebook channel works okay for very small brands, but there are many limitations:
