Welcome to my gig,A year ago, Apple announced that they would restrict the ability of the apps to track user behavior without the user's agreement. And now, in April 2021, they released this feature. All apps need to ask users to opt-in or opt-out from tracking. According to recent studies, 80% of users will opt out of tracking. FB CAPI it's the example of the next trick from companies that earn from advertising against privacy regulations policies.  And I'm here to help you implement Facebook Conversion API  because when Facebook is losing so much data, even your retargeting campaigns start pushing the same audiences and the optimization process is only making things harder for advertisers. But there is a solution, Facebook Conversion API will help you: Track events on your siteCollect users' data (first name, last name, etc.)Create audiences and segments based on the collected dataWith server-side tracking, you will prevent misinformation or lack of information. We will be using both browser and server tracking. It means that if your Facebook browser pixel is blocked, Facebook will still track users' data using the server.  Thank you Best regards Matt
