private ?FilesystemAdapter $cache;
private function sendRequest(string $method, string $url, array $param = null): array
{
try {
$options = ['headers' => $this->getHeader()];
if ($param !== null) {
$options['body'] = json_encode($param, true);
}
$response = $this->httpClient->request($method, $url, $options);
return json_decode($response->getContent(), true);
} catch (ClientException | ServerException | TransportException $e) {
return $this->handleZitadelError($e);
}
}

The security implementation showcases enterprise-level patterns with multi-factor validation and intelligent threat detection.
private function getAccessToken(): ?string
{
try {
$response = $this->httpClient->request('POST', $this->tokenEndpoint, [
'headers' => $this->getHeaderForFormUrlEncode(),
'body' => [
'client_id' => $this->clientId,
'client_secret' => $this->clientSecret,
'scope' => 'openid urn:zitadel:iam:org:project:id:zitadel:aud',
'grant_type' => 'client_credentials'
]
]);
$responseData = json_decode($response->getContent(), true);
if (!empty($responseData['access_token'])) {
$this->setCache($responseData);
return $responseData['access_token'];
}
} catch (Exception $exception) {
return null;
}
