Facebook Conversions API

The Facebook Conversions API allows advertisers to send events directly to Facebook via a server-side connection.

Server-side events are sent to Facebook via the Facebook Conversions API (formerly known as Facebook Server-Side API). The Facebook Conversions API enables you to measure events that may not happen in the browser, improve accuracy by tracking events both in the browser and on the server, and more.
