There are a few things you should know about Attribution in order for it to work properly with
  your campaigns.
  Facebook Developer Account 
If you will be utilizing the Localytics
   integration with Facebook, you will need to include the AdSupport Framework as detailed in the
    
Localytics
   iOS integration guide. You'll
   also need an active 
Facebook Developer Account.
Entering the Facebook App ID
   
   To enable Facebook attribution, you must edit each respective app in the Localytics Administration tab and include the
    Facebook Developer Application ID. Your Facebook Developer Application ID can be found by
    logging in to your Facebook Developer Account and clicking Apps. 
  AdSupport Framework (iOS only)
 In order for your app to be able to access
   the device identifiers that are required for most iOS acquisition to work, you must include
   AdSupport.framework as discussed in the  
iOS
    Integration Guide. You've likely already done this, but it's worth checking just to be
   sure. 
Google Play Services SDK (Android only)
 In order for your app to return
   the 
Google Advertising ID (GAID from devices running your app, you must
   include the Google Play Services SDK 4+. The use of GAID is not yet a requirement for app
   analytics on Android. However, if your Android app serves in-app advertising, your Google account
   manager may require your app to use GAID in place of Android ID. 
If you use a code obfuscation
    tool (e.g. ProGuard), please be sure to configure ProGuard such that the file paths to both the
     Localytics SDK and the Google Play Services
    SDK are exempt from obfuscation. More information can be found at the full Google Play Services SDK setup instructions.
