How to add Facebook cookies to your configuration

After initializing the Configuration script, you will have to instruct Cookie Saver what cookies to save. You may want to save the cookies set by Facebook pixel.

This guide explains which are Facebook cookies and how to added them to your configuration.

When the Facebook pixel tracking is implemented on your website, two cookies are set:

• "_fbp" is used to distinguish and keep track of your unique users.
• "_fbc" is only set when a user arrives at your website from an Ad, and the destination URL includes the click identifier "fbclid".

Both cookies are auto-updated/extended by Facebook with a default expiration of 90 days. As auto-update/extend can not be disabled, backup cookies will be required. This is the default setting of Cookie Saver. 

Configuration to be added with the Cookie Saver installation:

acq("addCookie", {
  "name": "_fbp",
  "expirationDays": 90
});
acq("addCookie", {
 "name": "_fbc",
 "expirationDays": 90
});
