Unable to see webhooks on Jira dashboard (created via Rest API) [PHP]

I was able to successfully create webhooks via api and was able to fetch from api as well. but am unable to see them in jira dashboard. please check my code here.

    <?php
$webhooksbase = 'https://api.atlassian.com/ex/jira/'.$site_id.'/rest/api/3/webhook';
$data = <<<REQUESTBODY
    {
      "url": "https://webhook.site/839d3c82-5da3-454f-9b70-52f33dc4c6ed",
      "webhooks": [
        {
          "events": [
            "jira:issue_updated"
          ],
          "fieldIdsFilter": [
            "summary"
          ],
          "jqlFilter": "project = TESTRAIL"
        }
      ]
    }
REQUESTBODY;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $webhooksbase);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'Accept: application/json',
    'Content-Type: application/json',
    'Authorization: Bearer ' . $result_decode['access_token']
]);
$result_issue = curl_exec($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
 
if (curl_errno($ch)) {
    echo 'Error:' . curl_error($ch);
}
curl_close($ch);
echo 'code:'. $httpcode.'<hr />Response: <br>';
 
?>
