Authorization Code Flow

$provider = new \WitteStier\OAuth2\Client\Provider\Meetup([
    'clientId' => '{meetup-consumer-key}',
    'clientSecret' => '{meetup-consumer-secret}',
    'redirectUri' => '{meetup-consumer-redirect-uri}',

// If we don't have an authorization code then get one.
if (isset($_GET['code']) === false) {

    // Fetch the authorization URL from the provider; this returns the urlAuthorize option and generates and applies 
    // any necessary parameters (e.g. state).
    $authorizationUrl = $provider->getAuthorizationUrl();

    // Get the state generated for you and store it to the session.
    $_SESSION['oauth2state'] = $provider->getState();

    // Redirect the user to the authorization URL.
    header('Location: ' . $authorizationUrl);

// Check given state against previously stored one to mitigate CSRF attack.
} elseif (empty($_GET['state']) === true || ($_GET['state'] !== $_SESSION['oauth2state'])) {

    exit('Invalid state');

} else {

    try {

        // Try to get an access token using the authorization code grant.
        $grant = new League\OAuth2\Client\Grant\AuthorizationCode();
        $accessToken = $provider->getAccessToken($grant, [
            'code' => $_GET['code']

    } catch (\League\OAuth2\Client\Provider\Exception\IdentityProviderException $e) {

        // Failed to get the access token or user details.


    // We have an access token, which we may use in authenticated requests against the service provider's API.
    echo $accessToken->getToken() . "\n";
    echo $accessToken->getRefreshToken() . "\n";
    echo $accessToken->getExpires() . "\n";
    echo ($accessToken->hasExpired() ? 'expired' : 'not expired') . "\n";

    try {

        // Using the access token, we may look up details about the resource owner.
        $resourceOwner = $provider->getResourceOwner($accessToken);


   } catch (\League\OAuth2\Client\Provider\Exception\IdentityProviderException $e) {

        // Failed to get the access token or user details.



Managing Scopes

When creating your Meetup authorization URL, you can specify the state and scopes your application may authorize.

$options = [
    'scope' => [ 'ageless', 'basic', 'event_management', 'group_edit', 'group_content_edit', 'group_join', 'messaging', 'profile_edit', 'reporting', 'rsvp' ],

$authorizationUrl = $provider->getAuthorizationUrl($options);

If neither are defined, the provider will utilize internal defaults.

At the time of authoring this documentation, the following scopes are available.

Refreshing a Token

$provider = new \WitteStier\OAuth2\Client\Provider\Meetup([
    'clientId' => '{meetup-consumer-key}',
    'clientSecret' => '{meetup-consumer-secret}',
    'redirectUri' => '{meetup-consumer-redirect-uri}',

// Fetch your token from a datastore.
$token = fetchAccessToken();

$refreshToken = $token->getRefreshToken();

if ($token->hasExpired() === true) {

    $grant = new League\OAuth2\Client\Grant\RefreshToken();
    $newAccessToken = $provider->getAccessToken($grant, [
        'refresh_token' => $token->getRefreshToken()

    // Purge old access token and store new access token to your data store.
