mysms api 登录并获取短信

Question

I am developing a program to be able to send and get SMSs using MySMS . I have the API Key and I managed to write a code for sending SMS. But I have a problem when trying to login to the api and get SMSs. I am using Postman and it is giving me response code 500 when I try to login.

https://api.mysms.com/rest/user/login

any clue on what I am doing wrong, all my data is correct but I am not sure about the format or any other thing.

image explaining the parameters and documentation and the response code

       $url      = 'https://api.mysms.com/json/user/login';
      $mydata  = array(
                        'apiKey'   => $apikey,
                        'msisdn'   => $msisdn,
                        'password' => $password,
                        
                    );
    $post_data = json_encode($mydata);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
    $headers = array();
    $headers[] = 'Content-Type: application/json';
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    $result = curl_exec($ch);
    if (curl_errno($ch)) {
        echo 'Error:' . curl_error($ch);
    }
    curl_close($ch);
    return $result;
