Laravel - Unable to Integrate Whatsapp with Twilio

Herewith I need to send a message to particular WhatsApp number by clicking a button. Twilio API used to send messages and configured by https://www.twilio.com/console. And also I registered and get ID and Token from Twilio to my personnel WhatsApp number. Below is my code.

abc.blade.php

<div class="col-md-6" align="center" style="margin-top: 30px;">
<button class="btn btn-sm pmd-btn-fab pmd-btn-flat pmd-ripple-effect btn-primary" type="button" style="margin-left: 10px; margin-top: 40px; width:100px;" onclick="sendMsg(this);">Upload</button></div>


<script type="text/javascript">

    function sendMsg()
    {

        $.ajax({
            url: "",
            type: "GET",
            dataType:"json",
            success: function (data) 
            {               
                alert("OK");
            }
        });
    }

</script>

Utils/Twilio.php

<?php 

    namespace Utils;

    class Twilio {

        private $sid = "AC967540fbaf69f951a3b42e229a93c110"; // Your Account SID from www.twilio.com/console
        private $token = "67bbbd8e95339a3db91b503a3f02fa34"; // Your Auth Token from www.twilio.com/console

        private $client;

        public function __construct() {
            $this->client = new \Twilio\Rest\Client($this->sid, $this->token);
        }

        public function sendSMS($from, $body, $to) {
            $message = $this->client->messages->create(
                $to, // Text this number
                array(
                  'from' => $from, // From a valid Twilio number
                  'body' => $body
                )
            );
            return $message->sid;
        }

    }

Controller.php

<?php

namespace App\Http\Controllers;

use NotificationChannels\ChatAPI\ChatAPIChannel;
use NotificationChannels\ChatAPI\ChatAPIMessage;
use Illuminate\Notifications\Notification;

use Utils\Twilio;

class Controller extends Notification
{
    public function via($notifiable)
    {
        return [ChatAPIChannel::class];
    }

    public function toChatAPI()
    {
        $result = ChatAPIMessage::create()
            ->to(947xxxxxxxx) // your user phone
            ->content('Hi bro....');

        return $result;
    }
}

On button click function nothing happen. Thanks in advance.
