title: "Average Daily Active Users" for Facebook API Limits
body: <p>I've suddenly started running into API limits. I've been restricting my API calls to: <code>number of users * 200</code>, but I'm getting error #4 about once per day.</p>
  
  <p>This calculation was based on the docs from end of 2015 that said number of users your app had yesterday, plus new logins today. </p>
  
  <p>But it looks like that has changed to:</p>
  
  <blockquote>
    <p>The number of users your app has is the average daily active users of your app, plus today's new logins</p>
  </blockquote>
  
  <p>Can someone explain to me what "average daily active users" is? And is there a way I can get access to this number?</p>

  <p>Some information on what I'm doing:</p>
  
  <p>My app fetches pages and posts from pages. To do this, I hit the Facebook API to get user's liked pages. Then each hour, I fetch posts from pages the system knows about. </p>
  
  <p>I do the following:</p>
  
  <ul>
   <li> Batch requests (50 per batch)
   <li> I'm only fetching posts since the last fetch (using since, until and limit params. 90% of the requests return 0 posts)
   <li> I'm only fetching posts from pages my users like 
   <li> I'm using my app token for these requests
   <li> I limit the number of calls per hour to users * 200
  </ul>
