The client is available as a composer packager that can be installed in any project using composer:

composer require hetzner-cloud-php/client

Since the client is compatible with any PSR-18 HTTP client, any commonly used HTTP client can be used thanks to our dependency on php-http/discovery. Once both dependencies have been installed, you may start interaction with Hetzner Cloud API:

/** @var string $apiKey */
$apiKey = $_ENV['HETZNER_CLOUD_API_KEY'];
$client = HetznerCloud::client($apiKey);

// Create a server
$response = $createdServer = $client->servers()->createServer([
    'name' => 'test-server',
    'server_type' => 'cpx11',
    'image' => 'ubuntu-24.04',
]);

echo $response->server->name; // 'test-server'
