Access denied to call LinkedIn's API

Question

I followed the steps to have an access token ( LinkedIn developer ). However, I have an error when I make a call to the API to Search People.

This is my code ;

Route::post('research', function()

{
    $c = curl_init();
    $firstName = Request::input('firstName'); $lastName = Request::input('lastName');
    $resource = '&first-name='.$firstName.'&last-name='.$lastName.'&sort=connections';
    $params = array(
        'oauth2_access_token' => Session::get('access_token'),
        'format' => 'json',
    );
    $postdata = http_build_query($params);
    $url = 'https://api.linkedin.com/v1/people-search?'.$postdata.$resource;
    curl_setopt($c, CURLOPT_URL, $url);
    curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($c, CURLOPT_HEADER, true);
    $output = curl_exec($c);
    if($output === false)
    {
        trigger_error('Erreur curl : '.curl_error($c),E_USER_WARNING);
        exit('error');
    }else{
        var_dump($output);
        exit('result');
    }
    curl_close($c);
});

And this is my error ;

{
  "errorCode": 0,
  "message": "Access to people search denied.",
  "requestId": "DHYNQTZDN8",
  "status": 403,
  "timestamp": 1426519095912
}

Could someone advise me to find a solution ?

Thank you in advance, David Meurisse

You require special permission from LinkedIn to use the People Search API. https://developer-programs.linkedin.com/documents/people-search-api
