• Authentication API
• Management API
• Manually decoding tokens
• Organizations
• Using PSR-17 and PSR-18 factories
• Cookies session storage
• PHP session storage

Strategy configurations

You should define the type of application you're integrating with the SDK using the strategy parameter.

use Auth0\SDK\Auth0;
use Auth0\SDK\Configuration\SdkConfiguration;

$configuration = new SdkConfiguration(
    strategy: SdkConfiguration::STRATEGY_API,
);

$auth0 = new Auth0($configuration);

Available choices are:

• SdkConfiguration::STRATEGY_REGULAR (Default) — for stateful applications. Requires domain, clientId and cookieSecret also be configured.
• SdkConfiguration::STRATEGY_API — for stateless applications. Requires domain and audience also be configured.
• SdkConfiguration::STRATEGY_MANAGEMENT_API — for stateless applications that only interact with the Management API. Requires either managementToken or clientId and clientSecret to also be configured.

Logging out

use Auth0\SDK\Auth0;
use Auth0\SDK\Configuration\SdkConfiguration;

$configuration = new SdkConfiguration(
    domain: '...',
    clientId: '...',
    clientSecret: '..',
    cookieSecret: '...',
);

$auth0 = new Auth0($configuration);

if ($auth0->getCredentials()) {
    header('Location: ' . $auth0->logout());
    exit;
}

Using refresh tokens

use Auth0\SDK\Auth0;
use Auth0\SDK\Configuration\SdkConfiguration;

$configuration = new SdkConfiguration(
    domain: '...',
    clientId: '...',
    clientSecret: '..',
    cookieSecret: '...',
);

// The `offline_access` scope is required to retrieve a refresh token.
$configuration->pushScope('offline_access');

$auth0 = new Auth0($configuration);

$session = $auth0->getCredentials();

if (null !== $session && $session->accessTokenExpired) {
    $auth0->renew();
}

Authentication API

Use Auth0->authentication() to access more advanced Authentication API calls. For example:

use Auth0\SDK\Auth0;
use Auth0\SDK\Configuration\SdkConfiguration;

$configuration = new SdkConfiguration(
    domain: '...',
    clientId: '...',
    clientSecret: '..',
    cookieSecret: '...',
);

$auth0 = new Auth0($configuration);
$api = $auth0->authentication();

$api->emailPasswordlessStart(
  email: 'someone@somewhere.com',
);

Management API

Use Auth0->management() to retrieve endpoint classes for interacting with the Management API.

use Auth0\SDK\Auth0;
use Auth0\SDK\Configuration\SdkConfiguration;
use Auth0\SDK\Utility\HttpResponse;

$configuration = new SdkConfiguration(
    managementToken: '...'
);

$auth0 = new Auth0($configuration);

// Request users from the /users Management API endpoint
$response = $auth0->management()->users()->getAll();

// Check if thee request successful:
if (HttpResponse::wasSuccessful($response)) {
    // Decode the JSON response into a PHP array:
    print_r(HttpResponse::decodeContent($response));
}

Manually decoding tokens

use Auth0\SDK\Auth0;
use Auth0\SDK\Token;
use Auth0\SDK\Configuration\SdkConfiguration;

$configuration = new SdkConfiguration(
    domain: '...',
    clientId: '...',
    clientSecret: '..',
    cookieSecret: '...',
);

$auth0 = new Auth0($configuration);

$token = $auth0->decode(
  token: '...',
  tokenType: Token::TYPE_TOKEN,
);

print_r($token);

Organizations

Configure one or more Organization IDs. Authentication will use the first configured Orgaization ID by default.

use Auth0\SDK\Auth0;
use Auth0\SDK\Configuration\SdkConfiguration;
use Auth0\SDK\Utility\HttpResponse;

$configuration = new SdkConfiguration(
    organization: ['org_1', 'org_2', 'org_...'],
);

$auth0 = new Auth0($configuration);
$session = $auth0->getCredentials();

if (null === $session || $session->accessTokenExpired) {
    // Begin the authentication flow using `org_1`:
    header('Location: ' . $auth0->login());
    exit;
}

You can process incoming organization invites from visitors by using the Auth0->handleInvitation() method.

For more advanced cases, you can use the Auth0->getInvitationParameters() methods to retrieve invitation data from the request.

Using PSR-17 and PSR-18 factories

Install PSR-17 and PSR-18 compatible libraries:

composer require kriswallsmith/buzz nyholm/psr7

Pass instances of those to the SDK during initialization:

use Auth0\SDK\Auth0;
use Auth0\SDK\Configuration\SdkConfiguration;
use Buzz\Client\MultiCurl;
use Nyholm\Psr7\Factory\Psr17Factory;

$Psr17Library = new Psr17Factory();
$Psr18Library = new MultiCurl($Psr17Library);

$configuration = new SdkConfiguration(
    httpClient: $Psr18Library,
    httpRequestFactory: $Psr17Library,
    httpResponseFactory: $Psr17Library,
    httpStreamFactory: $Psr17Library,
);

$auth0 = new Auth0($configuration);

Cookies session storage

Session data can be stored on authenticated user's devices:

use Auth0\SDK\Auth0;
use Auth0\SDK\Configuration\SdkConfiguration;
use Auth0\SDK\Store\CookieStore;

$configuration = new SdkConfiguration(
    strategy: SdkConfiguration::STRATEGY_REGULAR,
);

$cookies = new CookieStore($this, 'example_storage');

$configuration->setSessionStorage($cookies);

$auth0 = new Auth0($configuration);

The following options must also be configured to use a CookieStore:

• strategy must be SdkConfiguration::STRATEGY_REGULAR.
• cookieSecret — an encryption key for the session cookie.
• cookieDomain — when sharing session cookies across multiple subdomains, use your FQDN with a dot in front, e.g. .yourdomain.com.
• cookieExpires — the expiration time (in seconds) for the session cookie.
• cookiePath — path to use for the session cookie.
• cookieSecure — whether cookies should only be sent over secure connections.

PHP session storage

Session data can be stored in a combination of server side and user's devices:

use Auth0\SDK\Auth0;
use Auth0\SDK\Configuration\SdkConfiguration;
use Auth0\SDK\Store\SessionStore;

$configuration = new SdkConfiguration(
    strategy: SdkConfiguration::STRATEGY_REGULAR,
);

$cookies = new SessionStore($this, 'example_storage');

$configuration->setSessionStorage($cookies);

$auth0 = new Auth0($configuration);

As state data is stored on the server-side in this configuration, it's important to configure any load balanced PHP environments to use a shared storage method like memcache.
