Keycloak Admin REST API Client

PHP client to interact with Keycloak's Admin REST API.

Inspired by keycloak/keycloak-nodejs-admin-client.

Installation

Install via Composer:

composer require fschmtt/keycloak-rest-api-client-php

Usage

Example:

$keycloak = new \Fschmtt\Keycloak\Keycloak(
    baseUrl: 'http://keycloak:8080',
    username: 'admin',
    password: 'admin'
);

$serverInfo = $keycloak->serverInfo()->get();

echo sprintf(
    'Keycloak %s is running on %s/%s (%s) with %s/%s since %s and is currently using %s of %s (%s %%) memory.',
    $serverInfo->getSystemInfo()->getVersion(),
    $serverInfo->getSystemInfo()->getOsName(),
    $serverInfo->getSystemInfo()->getOsVersion(),
    $serverInfo->getSystemInfo()->getOsArchitecture(),
    $serverInfo->getSystemInfo()->getJavaVm(),
    $serverInfo->getSystemInfo()->getJavaVersion(),
    $serverInfo->getSystemInfo()->getUptime(),
    $serverInfo->getMemoryInfo()->getUsedFormated(),
    $serverInfo->getMemoryInfo()->getTotalFormated(),
    100 - $serverInfo->getMemoryInfo()->getFreePercentage(),
);

will print e.g.

Keycloak 25.0.0 is running on Linux/5.10.25-linuxkit (amd64) with OpenJDK 64-Bit Server VM/11.0.11 since 0 days, 2 hours, 37 minutes, 7 seconds and is currently using 139 MB of 512 MB (28 %) memory.

More examples can be found in the examples directory.

Customization

Custom representations & resources

You can register and use custom resources by providing your own representations and resources, e.g.:

class MyCustomRepresentation extends \Fschmtt\Keycloak\Representation\Representation
{
    public function __construct(
        protected ?string $id = null,
        protected ?string $name = null,
    ) {
    }
}

class MyCustomResource extends \Fschmtt\Keycloak\Resource\Resource
{
    public function myCustomEndpoint(): MyCustomRepresentation
    {
        return $this->queryExecutor->executeQuery(
            new \Fschmtt\Keycloak\Http\Query(
                '/my-custom-endpoint',
                MyCustomRepresentation::class,
            )
        );
    }
}

By extending the Resource class, you have access to both the QueryExecutor and CommandExecutor. The CommandExecutor is designed to run state-changing commands against the server (without returning a response); the QueryExecutor allows fetching resources and representations from the server.

To use your custom resource, pass the fully-qualified class name (FQCN) to the Keycloak::resource() method. It provides you with an instance of your resource you can then work with:

$keycloak = new Keycloak(
    $_SERVER['KEYCLOAK_BASE_URL'] ?? 'http://keycloak:8080',
    'admin',
    'admin',
);

$myCustomResource = $keycloak->resource(MyCustomResource::class);
$myCustomRepresentation = $myCustomResource->myCustomEndpoint();
