title: Automate data pull from App Annie API issue
body: <p>I am needing to automate a daily pull of app Annie data reviews and land them in S3. With the below I am trying to see if I can just pull one days worth of data but am getting an error 'TypeError: expected string or buffer'. I am new to python, can someone explain what I am doing wrong or another way to accomplish what I am trying to do?</p>
  
  <pre><code>import json
  import requests
  
  url = 'https://api.appannie.com/v1.2/apps/ios/app/331177714/reviews?       
  start_date=2016-1-01&amp;end_date=2016-6-26&amp;countries=US'
  key = 'Authorization: bearer 585e46.....'
  
  response = requests.get(url, 
                          headers = {'Authorization':'bearer 585e46.....'})   
  
  data = json.loads(response.json()) 
  </code></pre>
