title: Get all active campaigns from facebook ads api - how to set the filter
body: <p>I would like to get insights of all my active campaigns running on Facebook Ads. I manage to get all campaigns with FacebookAdsApi on my account but i am not able to use a filter so i only get campaigns with the "ACTIVE" status. </p>
  
  <p>Here is my code so far:</p>
  
  <pre><code>from facebookads.api import FacebookAdsApi
  from facebookads.objects import AdAccount, Ad, Insights, AdUser
  import datetime
  
  my_app_id = 'xxx'
  my_app_secret = 'xxx'
  my_access_token = 'xxx'
  FacebookAdsApi.init(my_app_id, my_app_secret, my_access_token)
  
  me = AdUser(fbid='me')
  my_accounts = list(me.get_ad_accounts())
  my_account = my_accounts[0]
  
  fields = [
      Insights.Field.campaign_name,
      Insights.Field.spend
  ]
  
  params = {
      'time_range': {'since': str(datetime.date(2015, 1, 1)), 'until': str(datetime.date.today())},
      'level': 'campaign',
      'limit': 1000
  }
  
  insights = my_account.get_insights(fields=fields, params=params)
  print len(insights)
  &gt;&gt;&gt; 115
  </code></pre>
  
  <p>I tried to add the following line to <code>params</code>:</p>
  
  <pre><code>filtering': [{'field': 'campaign.effective_status','operator':'IN','value':['ACTIVE']}]
  </code></pre>
  
  <p>which results in this error-msg:</p>
  
  <pre><code>"error_user_msg": "The reporting data you are trying to fetch has too many rows. Please use asynchronous query or restrict amount of ad IDs or time ranges to fetch the data."
  </code></pre>
  
  <p>I can get all campaigns from my account (115) without any issue and there are only 10 active campaigns at the moment so i guess my filter is wrong?</p>
