This simple script sets the _fbp and _fbc cookies when Pixel doesn't.
In Belgium, the served Pixel script is different than in the rest of the world: it's missing pieces of code for handling first-party cookies. This affects other parts of the Pixel code including the correct handling of tracking in iOS 14.5+, and prevents us from reading the cookies for use with the Conversion API.
This package is reimplements the missing piece of the Pixel which sets _fbc and _fbp.
<script async defer src="https://unpkg.com/set-fb-cookies">import setFbCookies from "set-fb-cookies";
setFbCookies();const setFbCookies = require("set-fb-cookies").default;
setFbCookies();Better yet, if you want to use only the Conversion API you can use this script to generate _fbc and _fbp which you can then pass to your Server. This makes it possible to skip using the browser Pixel.
