title: Google maps geocode API not working when using authentication
body: <p>I've set up a small PHP script that verifies user submitted address information with google's geocode API over CURL. </p>
  
  <pre><code>https://developers.google.com/maps/documentation/geocoding/#GeocodingRequests
  </code></pre>
  
  <p>It all works fine using the normal quota you get daily per IP. However whenever I try to authenticate using my API key I get a REQUEST_DENIED response.</p>
  
  <p>Successful response</p>
  
  <pre><code>http://maps.googleapis.com/maps/api/geocode/json?sensor=false&amp;address=Agadir
  </code></pre>
  
  <p>Request denied</p>
  
  <pre><code>http://maps.googleapis.com/maps/api/geocode/json?sensor=false&amp;address=Agadir&amp;key={my_api_key}
  </code></pre>
  
  <p>I've set up my project to allow access on that service (Google Maps API v3), and I'm certainly nowhere near the daily quota. I'm also 100% sure my API key is correct.</p>
  
  <p>Does anyone know if the API keys take some time to propagate?</p>
