cURL POST request in C++

I have cURL https request I am trying to send to my web server in a C++ program. I am getting back a "Bad Request" format response. 

CURL *curl;
CURLcode res;

curl_global_init(CURL_GLOBAL_ALL);
curl = curl_easy_init();
if(curl)
{
    int res = 0;
    snprintf(curl_url, sizeof(curl_url), "https://%s:8080/hello", results);
    snprintf(curl_fields, sizeof(curl_fields),"\"name\":\"%s\", \"key\":\"%s\"", name, data);


    struct curl_slist *headers = NULL;
    headers = curl_slist_append(headers, "Accept: application/json");
    headers = curl_slist_append(headers, "Content-Type: application/json");
    headers = curl_slist_append(headers, "charset: utf-8");

    curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
    curl_easy_setopt(curl, CURLOPT_URL, curl_url);
    curl_easy_setopt(curl, CURLOPT_POST, 1);
    curl_easy_setopt(curl, CURLOPT_POSTFIELDS, curl_fields);

    res = curl_easy_perform(curl);
    if ( res )
    {
        ---error---
    }
    curl_easy_cleanup(curl);
    curl_global_cleanup();
}

Can I get some help ?

Are you trying to send the following json?

{
  "name": name,
  "data": data
}

from this line of code

  snprintf(curl_fields, sizeof(curl_fields),"\"name\":\"%s\", \"key\":\"%s\"", name, data);

shouldn't it then be

  snprintf(curl_fields, sizeof(curl_fields),"{\"name\":\"%s\", \"key\":\"%s\"}", name, data);

(add the curly braces)
