Hello BHW community,
What is Facebook Conversion API?

Facebook CAPI has the same purpose as a Facebook pixel, but they have different technologies behind them.
The policies and restrictions made FB CAPI more tailored to the needs of the modern tracking environment. As for Facebook Conversion API, it doesn’t involve the user’s browser for sending tracking information. Everything is done through the cloud server. It makes user data more secure and accurate.
If we take a closer look at the link of Facebook ads, we will see that at the end of almost any URL, FB appends its additional parameter fbclid.
The pixel code on the landing page stores the value of this parameter in a cookie and then sends it along with any Facebook event. Along with click id (fbclid) Facebook uses browser ID (fbp). Fbp and fbc cookies helps FB determine what kind of user landed on your site and who converted.
FB can match users through other parameters such as email, phone number, first/last name, etc. The more user data you send to Facebook Conversion API, the higher the match rate you receive.
