Laravel HTTP Client not passing the data to API

Question

Controller request where I'm passing from parameters to API:

$response = Http::withOptions([
        'debug' => true,
        ])->post('https://starznets.com/api/login.php', [
        'dosubmit' => $request->dosubmit,
        'username' => $request->username,
        'password' => $request->password,
         ]);

     $body = $response->body();
     echo "<pre>";
     print_r($body);
     die;
