Example arduino codes for HTTPS GET/POST

Hello i currently have the W5500-EVB-Pico, and i would like to connect to AWS IoT via HTTPS (not MQTT). I already have the server setup, and i also have the certificates with me. But im having trouble looking for example codes of the W5500 module doing a HTTPS POST/GET, I am currently working on the arduino platform using Earle Philhower core. Can anyone point me to guides on how to set up the certificates?

Thank you

I found a good one

but the example code is generating some errors

#include <SPI.h>
#include <Ethernet.h>
#include <SSLClient.h>
#include "certificates.h"

// if you don't want to use DNS (and reduce your sketch size)
// use the numeric IP instead of the name for the server:
//IPAddress server(74,125,232,128);  // numeric IP for Google (no DNS)
//char server[] = "www.google.com";    // name address for Google (using DNS)
char server[] = "httpbin.org";  // name address for Google (using DNS)
