Facebook's Solution to Safari 11 Cookie Changes

On September 19, 2017, Apple released iOS 11 and with it, Safari’s new Intelligent Tracking Prevention that identifies the sites that users interact with the most, and limits cookies and other website data on all other domains. To help capture some of the missing events, Advanced Matching in the Facebook Pixel would allow you match more events with Facebook users by sending customer data you collect from your website (e.g email on checkouts) through the pixel. Please visit our Developer Documentation for instructions on how to get started.
