#  The example below shows how to integrate Clickatell's API into Layer's PVS Module.
#  Please be advised that we do not provide support for custom integrations. 
#
#  $phone will be automatically supplied, and contains the customer's phone number
#  $code will be automatically supplied, and contains a 4 digit code
#
#  Example is provided below


#provide api credentials
$apiid="123456";
$apiuser="username";
$apipassword="password123";

#provide the content of the SMS message - remember to include the $code variable in your message, as that is the code to be sent to the customer
$body="Hello! The verification code is: ".$code.". Thank you for verifying your account!";

#build the API request
$url = 'http://api.clickatell.com/http/sendmsg?' . http_build_query([
        'user' => $apiuser,
        'password' => $apipassword,
	'api_id' => $apiid,
        'to' => $phone,
        'text' => $body
    ]);

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$clickatell = curl_exec($ch);


#log the attempt to help troubleshoot
