Как добавить в cron задание?

session_start();
$data = array(
    'email' => '***********',
    'password' => '**********'
);
 
$payload = json_encode($data);

$ch = curl_init('****************************************');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json',
    'Content-Length: ' . strlen($payload))
);
$result = curl_exec($ch);
curl_close($ch);
var_export($result);
$json = json_decode($result);
$token = $json->data->token;
$_SESSION['token'] = $token;
