title: Error in sending Authorization through the header
body: <p>I'm working on a PHP Restful Api and for testing I'm using Chrome Advanced REST client and Postman, but the problem is that the api is working perfect on the localhost but on a public server when I want to send an authorization through the header, postman and advanced rest client both give me a json response including this error : "api key is missing" which means it doesn't recognize authorization!</p>
  
  <p>Please take a look at these two pics:</p>

  <p>Is there any solution for this problem?</p>
  
  <p>I would be very grateful for any help; Thanks in advance :)</p>
