Discord Webhooks With C++ - c++

Question

So I've taken up the challenge of doing webhooks in c++ and I wanted to just get some help with the post requests. Here is the code I have at the moment, I wanted to send embeds through post requests in C++.
Here is my code along with errors and all, the webhook is still active if you want to test yourself. Am trying to keep it all using windows librarys on purpose.
#include <winsock2.h>
#include <ws2tcpip.h>
#include <string>
#pragma warning(disable:4996)
#pragma comment(lib, "ws2_32.lib")
using namespace std;
int Plug(string address, string port, SOCKET* csock) {
WSADATA WSAData;
WSAStartup(MAKEWORD(2, 0), &WSAData);
PADDRINFOA result;
ADDRINFOA hints;
ZeroMemory(&hints, sizeof(ADDRINFO));
hints.ai_family = AF_INET;
hints.ai_socktype = SOCK_STREAM;
hints.ai_protocol = IPPROTO_TCP;
int res = getaddrinfo(address.c_str(), port.c_str(), &hints, &result);
*csock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
if (SOCKET_ERROR == connect(*csock, (SOCKADDR*)result->ai_addr, sizeof(SOCKADDR))) return WSAGetLastError();
return 0;
}
void Unplug(SOCKET* csock) {
closesocket(*csock);
WSACleanup();
}
string PostRequest(string host, string query, string data) {
string req = "POST " + query + " HTTP/1.1" + "\r\n";
req += "Host: " + host + "\r\n";
req += "Content-Type: application/x-www-form-urlencoded\r\n";
req += "Content-Length: " + to_string(data.length()) + "\r\n";
req += "Connection: Close";
req += "\r\n\r\n" + data + "\r\n\r\n";
SOCKET s;;
Plug(host, "80", &s);
Send(&s, req);
while (GetAvailable(&s) == 0) Sleep(10);
string result = Receive(&s);
//if (result.find("\r\n\r\n") == string::npos && DEBUG) return result;
//if (result.find("\r\n\r\n") == string::npos) return "PR_INVALID_RESPONSE";
//result = result.substr(result.find("\r\n\r\n") + 4, string::npos);
Unplug(&s);
return result;
}
int main() {
//https://discordapp.com/api/webhooks/705211476553629747/zwzqZMnTTgLtHBm3kc_DvvD71IW9FfE4ur-PQlkgeZhd56cT7UjSJCWI-V8wPiEUWV2w
std::cout<<PostRequest("162.159.129.233","/api/webhooks/705249405141516360/s8ioXr6IZEeuPnMi1O37CmY3o5pUZcu6ho7aIJdieSAqgGyTXOZjkOZdMNe1uJre6dto","{'embeds': [{'description': '**ERROR**: `TESTSTRING`\n', 'color': 4508791}]}");
}
However when I make the post requests it is unable to send my content and instead returns 400. I've tried a few more things but Im wondering if its my query?

And lets say I use discords actual ip instead of resolving it I end up getting
this instead

If you have any ideas dont hesitate to put them down below, ive been lost on this for a long time.

You could just use D++ to post to webhooks:
https://dpp.dev/classdpp_1_1webhook.html
In fact you could do everything with this lib instead of rolling your own solution.
