Webhook not working in Bitrix24?

Question

Bitrix24

Good day to all!
Tell me where the error is for the second day, I'm trying to transfer leads from Tilda to the Corporate Portal. Tilda transmits data to Bitrix, and Bitrix in response writes this:

[error_description] => No value entered for the required Subject field.
The value of the required field Project has not been entered.

The code itself:

<?
function writeToLog($data, $title = ''){
    $log = "\n------///BEGIN//////------------------\n";
    $log .= date("Y.m.d G:i:s") . "\n";
    $log .= (strlen($title) > 0 ? $title : 'DEBUG') . "\n";
    $log .= print_r($data, 1);
    $log .= "\n-----/// END ////-------------------\n";
    file_put_contents(getcwd() . '/hook.log', $log, FILE_APPEND);
    return true;
    echo "succes";
}

$defaults = array('TITLE' => '', 'NAME' => '', 'PHONE' => '', 'COMMENTS' => '', 'EMAIL' => '');
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
   $defaults = $_REQUEST;
    writeToLog($_REQUEST, 'webform PHP');
  
    $queryUrl  = 'https://какой-то сайт/rest/2363/какие-то циферки и буковки :-) /crm.lead.add.json';
    $queryData = http_build_query(array(
        'fields' => array(
         "TITLE" => $_REQUEST['TITLE'].' '.$_REQUEST['formname'],
                        "NAME" => $_REQUEST['NAME'],
                        "SOURCE_ID" => $_REQUEST['formname'], 
         "COMMENTS" => $_REQUEST['comments'],
         "EMAIL" => $_REQUEST['EMAIL'],
         "ASSIGNED_BY_ID" => 3655,
         "UF_CRM_SEARCH_WORD" => $_GET['utm_term'],
         "UF_CRM_LEAD_LANDING" => $_SERVER['HTTP_HOST'],
         "UF_CRM_CT_UTM_CAMP" => $_GET['utm_campaign'],
         "UF_CRM_CT_UTM_CONT" => $_GET['utm_content'],
         "UF_CRM_CT_UTM_MEDI" => $_GET['utm_medium'],
         "UF_CRM_CT_UTM_SOUR" => $_GET['utm_source'],
         "UF_CRM_CT_UTM_TERM" => $_GET['utm_term'],
         "STATUS_ID" => "NEW",
            "OPENED" => "Y", // ДОСТУПЕН ВСЕМ
            "PHONE" => array(array("VALUE" => $_REQUEST['PHONE'], "VALUE_TYPE" => "WORK" )),
            "EMAIL" => array(array("VALUE" => $_REQUEST['EMAIL_WORK'], "VALUE_TYPE" => "WORK" )),
            //"TITLE" => array("VALUE" => "Заказ с сайта"), 
        ),
        'params' => array("REGISTER_SONET_EVENT" => "Y")
    ));
  
  $curl = curl_init();
 curl_setopt_array($curl, array(
 CURLOPT_SSL_VERIFYPEER => 0,
 CURLOPT_POST => 1,
 CURLOPT_HEADER => 0,
 CURLOPT_RETURNTRANSFER => 1,
 CURLOPT_URL => $queryUrl,
 CURLOPT_POSTFIELDS => $queryData,
 ));

 $result = curl_exec($curl);
 curl_close($curl);

 $result = json_decode($result, 1);
 writeToLog($result, 'webform result CURL');

 if (array_key_exists('error', $result)) echo "Ошибка при сохранении лида: ".$result['error_description']."<br/>";
}

?>

Well, hook.log itself:

As I understand it, php itself worked, but the system "stumbled" on CURL.

Answer 1

Judging by the server responses in Bitrix24, you have the required fields "Subject" and "Project", which you do not pass in the CURL request
