title: Vkontakte HTTP API returns 'Incorrect signature'
body: <p>I have a problem using Vkontakte HTTP API. I'm trying to use the 'audio.search' method with my own VK application but with no success.</p>
  
  <p>A friend gave me an 'api_id', 'api_secret' and 'viewer_id' to test my code and works perfectly, but when I try to use the data from my own application it just returns "Incorrect signature: iframe/flash authorization".</p>
  
  <p>I'm using my user id as the 'viewer_id', my application id as 'api_id'  and the secure key of the application as 'api_secret'.</p>
  
  <p>Am I doing anything wrong? I can't find the solution.</p>
  
  <p>Thank you.</p>
