title: Using OAuth 2.0 for Devices :Some requested scopes were invalid
body: <p>After you have the client ID and client secret, you send an HTTP POST to the OAuth 2.0 device endpoint at <a href="https://accounts.google.com/o/oauth2/device/code" rel="nofollow">https://accounts.google.com/o/oauth2/device/code</a> with your client_id and a list of scopes. Unlike the other OAuth 2.0 flows, response_type and redirect_uri are not needed in the device flow. The following is an example request for a user code:</p>
  
  <p>POST /o/oauth2/device/code HTTP/1.1
  Host: accounts.google.com
  Content-Type: application/x-www-form-urlencoded</p>
  
  <p>client_id=812741506391-h38jh0j4fv0ce1krdkiq0hfvt6n5amrf.apps.googleusercontent.com&amp;
  scope=email%20profile</p>
  
  <p>I have tried but it results all time: </p>
  
  <p>{
    "error" : "invalid_scope",
    "error_description" : "Some requested scopes were invalid. {invalid=[rad365rad@gmail.com]}",
    "error_uri" : "<a href="http://code.google.com/apis/accounts/docs/OAuth2.html" rel="nofollow">http://code.google.com/apis/accounts/docs/OAuth2.html</a>"
  }</p>
