I am using following Laravel code to check webhook validation. But I unable to validate it, everytime it’s showing **“URL validation failed. Try again later.”**

if ($request-\>event === ‘endpoint.url\_validation’) {  
$hashForValidate = hash\_hmac(‘sha256’, $request-\>payload[‘plainToken’], env(‘ZOOM\_WEBHOOK\_SECRET\_TOKEN’));

```
    $response = [
        'message' => [
            'plainToken' => $request->payload['plainToken'],
            'encryptedToken' => $hashForValidate,
        ],
        'status' => 200,
    ];

    logger()->info($response['message']);

    return response()->json($response['message'], $response['status']);
}

```
