How to perform authorization with CURL?

Question

PHP

There is a webinar service, Bizon.
It is necessary to pull out certain data using API methods.
The documentation says:

In each request, it is necessary to pass the X-Token header with the value of the token received in the system interface, in the "Moderators, employees" section for a specific user

My CURL for test account:

function getViewers() {

    $url = 'https://online.bizon365.ru/api/v1/webinars/reports/get?webinarId=k21vrp8018';
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, ['X-Token' => 'r--zAKaFHBbxZfRtptHSWZbM0KaKBSWfWfAtpFrBbXZfRYaYS']);
    curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,0);
    curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,0);
    curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
    curl_setopt($ch,CURLOPT_HEADER,1);
    $res = curl_exec($ch);
    if(curl_exec($ch) === false)
            {
                echo 'Ошибка curl: ' . curl_error($ch);
            }
            else
            {
                echo 'Операция завершена без каких-либо ошибок';
            }
    curl_close($ch);

    return $res;

}

My answer is this (error 401)

Операция завершена без каких-либо ошибокstring(750) "HTTP/1.1 401 Unauthorized

How do I generally understand that the correct token has been transferred?
I see the answer, but I don't see the title anywhere X-Token, which I gave away.

Like this:
curl_setopt($ch, CURLOPT_HTTPHEADER, ['X-Token: r--zAKaFHBbxZfRtptHSWZbM0KaKBSWfWfAtpFrBbXZfRYaYS']);
PS: Write down, perhaps, a token for yourself ... :)
