Enabling this feature enhances events on the Conversions API Gateway using additional available user data from a Meta Pixel installed on your website. When you enable this feature, your Conversions API Gateway instance can set, update, and send a browser cookie with more complete user data from your Meta Pixel, to help you better match your events to Meta users.
Note: You can also launch your Conversions API Gateway instance in the Meta Events Manager Setting Tab. Look for the Conversions API Gateway section and select Launch.
In addition to user data that you provide manually, the following information will also be collected to enhance events, if available: email, name, phone number, city, state, gender, zip_code.
