Send data to 3rd party webhook by Pabbly Connect

[rabijit]

Hello,

I want to send customer data to a 3rd party webhook (Pabbly Connect) after checkout complete. I have written the following 

<?php
if (!defined("WHMCS"))
    die("This file cannot be accessed directly");

// Your pabbly webhook endpoint
$webhook_url = 'https://connect.pabbly.com/workflow/sendXXXXXXXXXXXXXXXXX';

/**
 * Post the request to pabbly webhook endpoint 
*/
 
function sendData($vars){
    $ch = curl_init($webhook_url);
    
    $jsonData = array(
        'OrderId' => $vars['orderid'],
        'amount' => $vars['amount']    
    );
    
    $jsonDataEncoded = json_encode($jsonData);
    
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $jsonDataEncoded);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); 
    $result = curl_exec($ch);
    logModuleCall('Pabbly-WHMCS', 'Send response to pabbly webhook endpoint', json_encode($jsonDataEncoded), print_r($output, true));
    
    curl_close($ch);
}

add_hook("ShoppingCartCheckoutCompletePage", 1, function($vars) {
        if($vars['ispaid'] == true) {            
            sendData($vars);
        }
});
 

I am getting the following logs in module log but nothing in pabbly end point. Can someone check and let me know if I miss anything?

Thanks in advance.
