Bagaimana cara Membuat Notifikasi ke Whatsaap

Assalamualaikum,.. Bisa menggunakan API dari Pihak Ketiga : https://wablas.com
penggunaannya di PHP nanti seperti ini :
<?php
$curl = curl_init();
$token = "API Key Disini";
$data = [
    'phone' => "081375231212",
    'message' => "Coba Kirimkan Pesan,..",
];
 
curl_setopt($curl, CURLOPT_HTTPHEADER,
    array(
        "Authorization: $token",
    )
);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($curl, CURLOPT_URL, "https://console.wablas.com/api/send-message");
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
$result = curl_exec($curl);
curl_close($curl);
