 $client = new \GuzzleHttp\Client();
```

Issue HTTP calls For example:

$res = $client->request('POST', https://webhook.site/your_url_id, ['query' => ['key1' => 'values1', 'key2' => 'value2'], 'verify' => false])`;

$res = $client->request('POST', 'https://webhook.site/your_url_id', ['body' => json_encode(['key1' => 'values1', 'key2' => 'value2']), 'verify' => false]);
