here is my webhook code
<?php
require_once 'facebook-php-ads-sdk-master/vendor/autoload.php';
use FacebookAds\Object\LeadgenForm;
use FacebookAds\Api;
use FacebookAds\Object\Ad;
use FacebookAds\Object\Lead;
$app_id='148247344564502719';
$app_secret='17489f3e0f8235645413f5dd593e67787';
$access_token='1482473465452719';
// Initialize a new Session and instanciate an Api object
Api::init($app_id, $app_secret, $access_token);
// The Api object is now available trough singleton
$api = Api::instance();
$challenge = $_REQUEST['hub_challenge'];
$verify_token = $_REQUEST['hub_verify_token'];
if ($verify_token === 'abc123') {
echo $challenge;
}
$input = json_decode(file_get_contents('php://input'), true);
error_log(print_r($input, true));
$form_id = $input['entry'][0]['changes'][0]['value']['form_id'];
$ad_id = $input['entry'][0]['changes'][0]['value']['ad_id'];
$leadgen_id = $input['entry'][0]['changes'][0]['value']['leadgen_id'];
/*$form = new Lead($leadgen_id);
$form->read();
$ad = new Ad($ad_id);
$leads = $ad->getLeads();*/
$form = new LeadgenForm($form_id);
$leads = $form->getLeads();
error_log(print_r($leads, true));
?>
here is the error :
Fatal error: Uncaught exception 'Exception' with message 'field 'id' is required.' in /www/wibonus/public_html/facebook-php-ads-sdk-master/src/FacebookAds/Object/AbstractCrudObject.php:123 Stack trace: #0 /www/wibonus/public_html/facebook-php-ads-sdk-master/src/FacebookAds/Object/Ad.php(290): FacebookAds\Object\AbstractCrudObject->assureId() #1 /www/wibonus/public_html/webhook.php(38): FacebookAds\Object\Ad->getLeads() #2 {main} thrown in /www/wibonus/public_html/facebook-php-ads-sdk-master/src/FacebookAds/Object/AbstractCrudObject.php on line 123

Instead of using Facebook SDK you can do simple CURL request from your PHP code to retrieve lead form data.
Here is the code.
$challenge = $_REQUEST['hub_challenge'];
$verify_token = $_REQUEST['hub_verify_token'];
if ($verify_token === 'abc123') {
echo $challenge;
}
$input = json_decode(file_get_contents('php://input'), true);
error_log(print_r($input, true));
$form_id = $input['entry'][0]['changes'][0]['value']['form_id'];
$ad_id = $input['entry'][0]['changes'][0]['value']['ad_id'];
$leadgen_id = $input['entry'][0]['changes'][0]['value']['leadgen_id'];
$challenge = $_REQUEST['hub_challenge'];
$verify_token = $_REQUEST['hub_verify_token'];
if ($verify_token === 'abc123') {
echo $challenge;
}
$input = json_decode(file_get_contents('php://input'), true);
error_log(print_r($input, true));
$form_id = $input['entry'][0]['changes'][0]['value']['form_id'];
$ad_id = $input['entry'][0]['changes'][0]['value']['ad_id'];
$leadgen_id = $input['entry'][0]['changes'][0]['value']['leadgen_id'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://graph.facebook.com/v2.8/" . $leadGenId . "?access_token={ACCESS_TOKEN}");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
$leadData = json_decode($result, true);
$lead = [];
for($i = 0; $i < count($leadData); $i++)
{
$lead[$leadData[$i]['name']] = $leadData[$i]['values'][0];
}
print_r($lead);
You should return $challenge in your callback URL. (Note:If you are working on webhook)
