Where can I find/set Endpoint in Dwolla Sandbox?

API Support
1

I wanted to create webhooks, now for that I need to create a webhook subscription.

$webhookApi = new DwollaSwagger\WebhooksubscriptionsApi($apiClient);
$subscription = $webhookApi->create(array (
‘url’ => ‘http://url.com’,
‘secret’ => ‘mysecret’,
));
I got the secret here, but what will be url? I know it is end point.
This is example I got from one of your member in community.

First, write your website and endpoint in the app settings on the dwolla website. (It’s currently under “edit features”).

(i.e. https://www.mypage.com/coolendpoint )

Make sure that your app listens to port 80 for http or port 443 for https.

But I am currently in sabndbox enviroment, where I can find endpoint in the app settings. There is no such tab, can you please hellp me out from where I can get it?

Error: Class "App\Http\Controllers\User\DwollaSwagger\WebhooksubscriptionsApi

I am getting this error… when I wrote code
public function dummy(Request $request){
try{
\DwollaSwagger\Configuration::$username = $this->dwolla_username;
\DwollaSwagger\Configuration::$password = $this->dwolla_password;
$apiClient = new \DwollaSwagger\ApiClient($this->dwolla_link);
$webhookApi = new DwollaSwagger\WebhooksubscriptionsApi($apiClient);
$tokensApi = new \DwollaSwagger\TokensApi($apiClient);
$appToken = $tokensApi->token();
\DwollaSwagger\Configuration::$access_token = $appToken->access_token;

    $subscription = $webhookApi->create(array (
      'url' => 'http://localhot:8000',
      'secret' => 'sshhhhhh',
    ));
    return $subscription;
  }
  catch (\Exception $e) {
    dd($e);
    $errorbody = json_decode($e->getResponseBody());
    $response['status_code'] = 401;
    $response['message'] = $errorbody->message;
    echo json_encode($response); die;
}

}
