title: does "app_key" means the same as "app_code" for HERE geocoding credentials on Python?
body: <p>I am trying to geocode some addresses with python
  so I created a freemium account on <a href="https://developer.here.com" rel="nofollow noreferrer">https://developer.here.com</a>
  my code is this</p>
  
  <pre><code>(...)
  here = Here(here_config.app_id, here_config.app_code, timeout=5)
  here.geocode(string_to_geocode)
  </code></pre>
  
  <p>I am getting the following error message:</p>
  
  <pre><code>HTTP Error 401: Unauthorized
  </code></pre>
  
  <p>my doubt comes from the difference between the terms <em>"app_code"</em> on my code sample and <em>"app_key"</em> on my credential screen.
  Is there another step I need to do in order to get a <em>"app_code"</em> or is my <em>"app_key"</em> already supposed to be it?</p>
  
  <p>P.S. on that same screen Here provides me an option of getting JAVASCRIPT keys, HERE SDK FOR IOS (PREMIUM EDITION) [this option cleary has a button that says "generate app_key and app_code", however, I am not developing a cellphone app, but a python program.
  What am I missing ?</p>
