Facebook Cookies
Understand how AnyTrack handles the Facebook _fbp cookie and the fbclid click ID, how AnyTrack builds the fbc value, and how these values reach the Meta Conversion API with every conversion event.
Meta Ads uses cookies to support its attribution and tracking processes. The two main cookies relevant for advertisers are _fbc and _fbp.
AnyTrack records the value of the _fbp cookie and the Meta click ID (fbclid). AnyTrack does not read the _fbc cookie. AnyTrack builds the fbc value from the stored fbclid value, and sends fbc and fbp with the conversion events that it sends to the Conversion API.
