Get list of private Dailymotion videos

I want to get list of private Dailymotion videos.

I am able to receive an access token with a private key. But then when I send Get request to retrieve the list of videos, I see the following “400 Bad Request: malformed Host header”.

<?php
            //Perform authentication
            // Specify the URL and data
$url = "https://partner.api.dailymotion.com/oauth/v1/token";

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

$headers = array(
   "Host: partner.api.dailymotion.com",
   "Content-Type: application/x-www-form-urlencoded",
);
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);

$data = "grant_type=client_credentials&client_id=xxx&client_secret=xxx&scope=manage_videos";

curl_setopt($curl, CURLOPT_POSTFIELDS, $data);

$resp = curl_exec($curl);
curl_close($curl);
$data = json_decode($resp, true);
$access_token = $data['access_token'];
$url = "https://partner.api.dailymotion.com/user/userid/videos?fields=id&limit=30&private=true";

$curl = curl_init($url);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

$headers = array(
    "Host: partner.api.dailymotion.com/rest",
);

$auth = "Authorization: Bearer " . $access_token;
$headers[1] = $auth;
curl_setopt($curl, CURLOPT_HTTPHEADER, $headers);

$resp = curl_exec($curl);
curl_close($curl);
//var_dump($resp);
?>

When I omit host in headers I get 404 Not Found.

    $headers = array(

);

$auth = "Authorization: Bearer " . $access_token;
$headers[0] = $auth;

I also tried to use the following url. I get 404 Not Found.

$url = "https://partner.api.dailymotion.com/videos?fields=id&private=true&owners=userid;
