Are you sure? Seem to recall needing FB SDK to manage marketing pixels that provide detail on marketing campaign analytics. If you’re spending money on those platforms to drive traffic you’re going to want to optimize your spend and see performance. To do that I believe you need the FB sdk - are you saying there’s an alternative or are you saying “just don’t optimize performance”.
Can't you optimize ad performance by generating unique URLs for each campaign and then counting the number of clicks/installs per campaign on your own infrastructure?
