Authorization Code Flow

$provider = new League\OAuth2\Client\Provider\Google([
    'clientId'     => '{google-app-id}',
    'clientSecret' => '{google-app-secret}',
    'redirectUri'  => 'https://example.com/callback-url',
    'hostedDomain' => 'https://example.com',

if (!empty($_GET['error'])) {

    // Got an error, probably user denied access
    exit('Got error: ' . htmlspecialchars($_GET['error'], ENT_QUOTES, 'UTF-8'));

} elseif (empty($_GET['code'])) {

    // If we don't have an authorization code then get one
    $authUrl = $provider->getAuthorizationUrl();
    $_SESSION['oauth2state'] = $provider->getState();
    header('Location: ' . $authUrl);

} elseif (empty($_GET['state']) || ($_GET['state'] !== $_SESSION['oauth2state'])) {

    // State is invalid, possible CSRF attack in progress
    exit('Invalid state');

} else {

    // Try to get an access token (using the authorization code grant)
    $token = $provider->getAccessToken('authorization_code', [
        'code' => $_GET['code']

    // Optional: Now you have a token you can look up a users profile data
    try {

        // We got an access token, let's now get the owner details
        $ownerDetails = $provider->getResourceOwner($token);

        // Use these details to create a new profile
        printf('Hello %s!', $ownerDetails->getFirstName());

    } catch (Exception $e) {

        // Failed to get user details
        exit('Something went wrong: ' . $e->getMessage());


    // Use this to interact with an API on the users behalf
    echo $token->getToken();

    // Use this to get a new access token if the old one expires
    echo $token->getRefreshToken();

    // Number of seconds until the access token will expire, and need refreshing
    echo $token->getExpires();

Refreshing a Token

Refresh tokens are only provided to applications which request offline access. You can specify offline access by setting the accessType option in your provider:

$provider = new League\OAuth2\Client\Provider\Google([
    'clientId'     => '{google-app-id}',
    'clientSecret' => '{google-app-secret}',
    'redirectUri'  => 'https://example.com/callback-url',
    'accessType'   => 'offline',

It is important to note that the refresh token is only returned on the first request after this it will be null. You should securely store the refresh token when it is returned:

$token = $provider->getAccessToken('authorization_code', [
    'code' => $code

// persist the token in a database
$refreshToken = $token->getRefreshToken();

If you ever need to get a new refresh token you can request one by forcing the approval prompt:

$authUrl = $provider->getAuthorizationUrl(['approval_prompt' => 'force']);

Now you have everything you need to refresh an access token using a refresh token:

$provider = new League\OAuth2\Client\Provider\Google([
    'clientId'     => '{google-app-id}',
    'clientSecret' => '{google-app-secret}',
    'redirectUri'  => 'https://example.com/callback-url',

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


If needed, you can include an array of scopes when getting the authorization url. Example:

$authorizationUrl = $provider->getAuthorizationUrl([
    'scope' => [
header('Location: ' . $authorizationUrl);
