How to redirect particular page after login via social networking site?
You can use user_login_destination() for your requirement which third-party authentication modules may use to determine the proper destination after a user has been properly logged in.

function user_login_destination() {
  $destination = drupal_get_destination();
  if ($destination['destination'] == 'user/login') {
    $destination['destination'] = 'user';
  }
  return $destination;
}


You just need to change line 4 to:

$destination['destination'] = '&lt;path you want to go to after login&gt;';
