title: Facebook ad account group API access not correct on Facebook's site
body: <p>I'm trying to build an application that will help manage different ad accounts for different customers (multiple businesses, so it has to handle multiple ad accounts). I'm looking at the ads API documentation for ad account groups, and the examples aren't working in the graph API explorer. Things like GET requests to </p>
  
  <p><code>https://graph.facebook.com/v2.4/&lt;AD_ACCOUNT_GROUP_ID&gt;/users</code> </p>
  
  <p>(from Facebook's documentation <a href="https://developers.facebook.com/docs/reference/ads-api/adaccountgroup/v2.4#read" rel="nofollow">here</a>) are returning the following error:</p>
  
  <pre><code>{
      "error": {
          "message": "(#275) Ad account cannot be determined for this request", 
          "type": "OAuthException", 
          "code": 275
      }
  }
  </code></pre>
  
  <p>As best as I can tell, the documentation is incorrect - I think it can't tell the difference between an ad account ID and an ad group ID (I know this pattern is also used for things like managing custom audiences which is why I'm guessing it thinks it should be seeing an add account ID). Is there a better guide on updating ad account group membership via the API I can reference, or an endpoint I can substitute in for Facebook's official documentation?</p>
