Pass Hashed Information for Facebook Advanced Matching
Overview
Facebook has a way for attribution providers and customers to send up hashed information about users to enhance how they do matching for attribution and analytics. With this data, Facebook can match conversion events to your customers to optimize your ads and build larger re-marketing audiences.
