Bagaimana cara mengirimkan secara automatis detail pembelian ke whats app dan email pembeli di marketplace

Assalamualaikum,.. bisa menggunakan API WA Gateway, misal dari wablas.com
pada controller : C:\xampp\htdocs\marketplace\application\controllers\Members.php
pada function selesai_belanja(), baris 214 didalamnya nanti tambahkan proses untuk kirim ke WA via API wablas, begini scriptnya :
 
<?php
$telepon = $res['no_telpon'];
$curl = curl_init();
$token = "Masukkan API key dari wablas disini...";
$data = [
	'phone' => "$telepon",
	'message' => "$message",
];
 
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);
