title: Get traffic incident data from 'here' with free public basic plan
body: <p>I try to get traffic data for (example) the A4 between Wenden,- and Engelskirchen, Germany. I am using this link scheme:</p>
  
  <pre><code>https://traffic.api.here.com/traffic/6.1/incidents.xml?bbox=50.98690,7.40913;50.96840,7.87189&amp;app_id={MY_FREE_API_PLAN_APP_ID}&amp;app_code={MY_FREE_API_PLAN_APP_CODE}
  </code></pre>
  
  <p>But the xml which I get says only:</p>
  
  <pre><code>&lt;Error_Message&gt;&lt;Error&gt;This is not a valid app_id and app_code pair.
  Please verify that the values are not swapped between the app_id and
  app_code and the values provisioned by HERE (either by your customer
  representative or via http://developer.here.com/myapps) were copied
  correctly into the request.&lt;/Error&gt;&lt;Error_description&gt;NA&lt;/Error_description&gt;
  &lt;/Error_Message&gt;
  </code></pre>
  
  <p>The APP_ID and APP_CODE are 100% right. I want to use this data for home / there's no commercial use planed at this point.</p>
  
  <p>Is there an mistake in my request for the data or want 'here' tell me on this way that I have to buy for the data?</p>
