Rest Apiv2 to retrieve messages with authentication

Nav - 

You need to request an access token and need to pass it with LIQL query. 

Please follow below article to request an access token.

Hi TariqHussain,

Thanks for your reply. I used below 

$aurl = "https://community.xxxxx.com/auth/oauth2/authorize?client_id=xxxxxxx&response_type=code&redirect_uri=http://redirect.xxx.com/getaccessToken";
print_r($aresponse = drupal_http_request($aurl, array('headers' => array('client_id' => 'xxxx','Content-Type' => 'application/json' ))));
exit;

I received 

stdClass Object ( [code] => -110 [error] => Connection timed out )

Did I miss anything and what is the redirect Url? 

Thanks.

You can get the Redirect URL from the app which you have created on community.

redirectreason=notregistered
