OAuth2 returns invalid_client error

a good day,

I'm having trouble getting an access token. I followed the guide here: http://developers.box.com/oauth/ and already get my client_id , client_secret and set redirect_uri in the application settings (OAuth2 parameters).

Here is the code for the client.php file

<?php
    $client_id = 'my_client_id_here'; //removed
    $post_url = 'https://www.box.com/api/oauth2/authorize';

    include 'includes/header.php';
?>
    <div id="content">
        <form action="<?php echo $post_url; ?>" type="POST" enctype="application/x-www-form-urlencoded">
            <input type="text" name="response_type" value="code">
            <input type="text" name="client_id" value="<?php echo $client_id; ?>">
            <input type="text" name="state" value="vexhax97td8xf_SomeTemporaryValueForTesting">
            <input type="submit">
        </form>
        <div id="response"></div>
    </div>

<?php
    include 'includes/footer.php';
?>

and here is the code for something.php file (here will be < redirect_uri )

<?php

$client_id =  'my_client_id_here'; //removed
$client_secret =  'my_client_secrect_here'; //removed
$post_url = 'https://www.box.com/api/oauth2/token';

$code = $_GET['code'];

include 'includes/header.php';

$fields_params = array(
        "grant_type" => 'authorization_code',
        "code" => $code,
        "client_id" => $client_id,
        "client_secret" => $client_secret
    );

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $post_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields_params);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Accept: application/json'
));

$data = curl_exec($ch); 
curl_close($ch);

$json = json_decode($data, true);
var_dump($json);

?>
    <div id="content">
        <?php 
            //Nothing fancy, just for displaying passed values
            if (isset($_GET))
                var_dump($_GET); 

            if (isset($_POST))
                var_dump($_POST); 
        ?>
    </div>

<?php
    include 'includes/footer.php';
?>

... now what happens

1.) in the first step ( client.php ), there is a form with a submit button.

2.) After I clicked the submit button, I am redirected to the Box login page with the "Authorize" button.

3.) . redirect_uri, (something.php), curl-, , , :

array(2) { ["error"]=> string(14) "invalid_client" ["error_description"]=> string(34) "The client credentials are invalid" }

, client_id client_secret, . URL- redirect_uri, SSL.

, , ?

JS

authorizeUser = function(){    

        var results = $.ajax({

            // The URL to process the request
            url : 'https://www.box.com/api/oauth2/token',
            type : 'POST',
            data : {
                grant_type : 'authorization_code',
                code : data.boxAuthorizationCode,
                client_id : data.clientId,
                client_secret : data.clientSecret
            },
            beforeSend: function (xhr) {
  xhr.setRequestHeader("Authorization", "Bearer $token")
},
            dataType: "json",
            success: function(response) {
               //console.log(response);
               console.log(response.access_token);
               data.access_token = response.access_token;
               tokenGranted();
            }

        });

        return results.responseText;

    },
