Requirements and installation

This requires at least PHP 7.1.

Version Supported
PHP 5.6 No
PHP 7.0 No
PHP 7.1 Yes
PHP 7.2 Yes
PHP 7.3 Yes


  1. Add "samuelthomas2774/oauth-client": "~3.0.0" to your composer.json
        "require": {
            "samuelthomas2774/oauth-client": "~3.0.0"
  2. Run Composer
    This will automatically download the latest patch version.
    composer install


  1. Include vendor/autoload.php in all pages that need access to any provider
    This will load any class in the src directory when used.
    require_once __DIR__ . '/vendor/autoload.php';
  2. Create a new OAuth2\\OAuth object with the parameters $client_id, $client_secret and $options
    The $options array must have at least base_api_endpoint, authorise_endpoint and token_endpoint.
    use OAuth2\GenericOAuthProvider;
    $client_id = 'client-id';
    $client_secret = 'client-secret';
    $client = new GenericOAuthProvider($client_id, $client_secret, null, [
        'session_prefix' => 'facebook_',
        'base_api_endpoint' => '',
        'authorise_endpoint' => '',
        'token_endpoint' => 'oauth/access_token', // Relative to the base API URL
  • To get a link to the authorise page:
    $redirect_url = '';
    $scope = ['email', 'user_friends']; // Optional scope array
    // Returns an OAuth2\AuthoriseUrl object
    // This will be converted to a string automatically if needed
    // You can use this object to get the OAuth2\State object to store extra state data accessible with
    // $client->getRequestState() when the user accepts/rejects the authorise request
    $login_url = $client->generateAuthoriseUrlAndState($redirect_url, $scope);
    // Add data to the state object
    // Every time generateAuthoriseUrlAndState is called a new state object will be created with separate data,
    // so you can have multiple authorise links on the same page and have the authorise response page react differently
    // depending on which link was used
    $login_url->getState()->next_url = '/';
    // You can also set the state parameter yourself (not recommended)
    // $login_url->getState() will still return a state object, but the attached data won't be saved
    // Use $login_url->getStateId(), $login_url->getState()->getId() or cast the state object to a string to get the
    // value of the state parameter
    $state = '...'; // Generate a random value and store in somewhere the next page can access (or set to null to not set a state parameter)
    $login_url = $client->generateAuthoriseUrl($state, $redirect_url, $scope);
  • To get an access token from the code that was returned:
    // Validates the request state and returns an OAuth2\AccessToken object
    $token = $client->getAccessTokenFromRequestCodeAndState();
    // You can also validate the state and pass the redirect url and an optional requested scope array yourself
    // Only do this if you set the state parameter when you generated the authorise link
    $redirect_url = ''; // Must match the $redirect_url given to generateAuthoriseUrl exactly
    $requested_scope = ['email', 'user_friends']; // Optional requested scope array to include in the AccessToken object
    $token = $client->getAccessTokenFromRequestCode($redirect_url, $requested_scope);
  • To get an access token a refresh token:
    // Returns an object of data returned from the server
    // This may include a new refresh_token
    // $token can be a string (a refresh token) or an AccessToken object with a refresh token returned by all
    // getAccessToken* methods
    $new_token = $oauth->getAccessTokenFromRefreshToken($token);
  • To make API requests with the access token:
    try {
        $response = $client->api('GET', 'me' /*, $guzzle_options = [] /*, $auth = null */);
    } catch (Exception $error) {
        echo 'OAuth provider returned an error: ' . print_r($error, true);
  • To get/set the current access token: You do not need to do this at the start of the script to get the access token from the session, this is done automatically. Also, this function updates the access token in the session.
    // Get
    $token = $client->getAccessToken();
    // Set
    // Set without updating the access token in the session
    $client->setAccessToken($new_token, false);

* This URL is for the default instance used

All the built-in providers implement OAuth2\UserProfilesInterface, which adds an extra method to get a OAuth2\UserProfile object.

try {
    $user = $client->getUserProfile();
} catch (Exception $error) {
    echo 'OAuth provider returned an error: ' . print_r($error, true);

Some also implement OAuth2\UserPicturesInterface (P), which adds a method to get the URL of the user's picture/avatar.

try {
    $picture_url = $client->getUserPictureUrl();
} catch (Exception $error) {
    echo 'OAuth provider returned an error: ' . print_r($error, true);

As GitLab and Mastodon support multiple instances they implement OAuth2\MultipleInstancesInterface, which adds an option and method to set the instance's URL.

use OAuth2\Providers\GitLab\GitLab;

$client = new GitLab($client_id, $client_secret, null, [
    'instance_url' => '',


Additional methods for providers

Facebook and Discord have additional methods.

Extending the OAuth2 class

You can extend the OAuth2 and other classes to add new functions and make existing functions work differently:

use OAuth2\Providers\Facebook\Facebook;

class My_Extended_Facebook_Class extends Facebook
    // Change the base_api_endpoint option to use a different API version
    public $base_api_endpoint = '';

    // Add a new function for getting the current user's ID
    public function getUserId(): string
        $user = $this->getUserProfile(['id']);
        return $user->id;

You can then use the newly created class:

$client = new My_Extended_Facebook_Class('client-id', 'client-secret');

try {
    echo 'Your Facebook User ID (for this app) is: ' . htmlentities($client->getUserId());
} catch (Exception $exception) {
    echo 'Facebook returned an error: ' . $exception->getMessage();
