title: using postman to access firebase REST API
body: <p>I'm trying to use postman to do REST API calls to firebase. I've managed to read from firebase when my security rule is to permit all users including unauthorized ones.</p>
  
  <p>but when I use this rule :</p>
  
  <pre><code>{"rules":{".read": "auth != null", ".write": "auth != null"}}
  </code></pre>
  
  <p>I get 'error' : 'permission denied' from postman.
  I did the request token for google's web oauth2.0 client and got the authorization_code token back.</p>
  
  <p>I tried to use token in the URL and in the header, tried it with GET &amp; POST request and still get denied.</p>
  
  <p>please help.
  Thanks in advance</p>
