Guys,
So I'm trying to find a perl script to request an OAUTH2 Access Token, and I've came across a few which haven't worked out. So I stumbled on this script for the chilkat module but it also doesn't work, but I think it seems promising. The script code and error outputs are below. Can someone please let me know what I'm doing wrong? I downloaded the correct chilkat version for my perl version and did not get any errors when manually installing the module.

#!/usr/bin/perl -w
use strict;
use warnings;
use chilkat();

$rest = chilkat::CkRest->new();

#  URL: https://xxx.xx.xx.xx/api/v2/access/token
$bTls = 1;
$port = 443;
$bAutoReconnect = 1;
$success = $rest->Connect("xxx.xx.xx.xx",$port,$bTls,$bAutoReconnect);
if ($success != 1) {
    print "ConnectFailReason: " . $rest->get_ConnectFailReason() . "\r
+\n";
    print $rest->lastErrorText() . "\r\n";
    exit;
}

$rest->SetAuthBasic("username","password");

$json = chilkat::CkJsonObject->new();
$json->UpdateString("grant_type","client_credentials");

$rest->AddHeader("Content-Type","application/json");

$sbRequestBody = chilkat::CkStringBuilder->new();
$json->EmitSb($sbRequestBody);
$sbResponseBody = chilkat::CkStringBuilder->new();
$success = $rest->FullRequestSb("POST","/api/v2/access/token",$sbReque
+stBody,$sbResponseBody);
if ($success != 1) {
    print $rest->lastErrorText() . "\r\n";
    exit;
}

$respStatusCode = $rest->get_ResponseStatusCode();
if ($respStatusCode >= 400) {
    print "Response Status Code = " . $respStatusCode . "\r\n";
    print "Response Header:" . "\r\n";
    print $rest->responseHeader() . "\r\n";
    print "Response Body:" . "\r\n";
    print $sbResponseBody->getAsString() . "\r\n";
    exit;
}

$jsonResponse = chilkat::CkJsonObject->new();
$jsonResponse->LoadSb($sbResponseBody);

$access_token = $jsonResponse->stringOf("access_token");
$created_at = $jsonResponse->stringOf("created_at");
$expires_in = $jsonResponse->IntOf("expires_in");
$refresh_token = $jsonResponse->stringOf("refresh_token");
$token_type = $jsonResponse->stringOf("token_type");
$account_id = $jsonResponse->IntOf("account_id");
