For your convenience, Localytics
  maintains direct, server-to-server integrations with about twenty-five of the largest mobile
  acquisition sources, which are referred to as integrated partners in the Attribution
  Dashboard.
  With integrated partners, 
Localytics will 
    - attribute your app's new users to an acquisition source or campaign, enabling you to measure
     and analyze the performance of your paid campaigns in Localytics
- notify your acquisition partner of each new user that the partner helps you acquire, giving
     your acquisition partner better insight into the performance of your campaigns
The largest mobile user acquisition sources, Facebook and Twitter, impose data retention and
   process controls on the analytics data available to advertisers. 
Localytics manages the complexity of these
   relationships on your behalf. We are currently the only app analytics platform that can provide
   granular analysis into the users you acquire from Facebook.
