README

This package provides BookingSync OAuth 2.0 support for the PHP League's OAuth 2.0 Client.

Deprecation warning

This lib use old deprecated vendors. You may have an SSL certificate issue. To solve it, you should:

• Replace the cacert.pem file in the deprecated GuzzleHttp repo with an updated one from https://curl.haxx.se/docs/caextract.html
• The location of the old pem file is vendor/guzzle/guzzle/src/Guzzle/Http/Resources/cacert.pem

Installation

To install, use composer:

composer require bookingsync/oauth2-bookingsync-php

Usage

Usage is the same as The League's OAuth client, using \Bookingsync\OAuth2\Client\Provider\Bookingsync as the provider.

Authorization Code Flow

$provider = new Bookingsync\OAuth2\Client\Provider\Bookingsync([
    'clientId'          => 'XXXXXXXX',
    'clientSecret'      => 'XXXXXXXX',
    'redirectUri'       => 'https://www.example.com/callback-url', // https is mandatory for BookingSync
    'scopes'            => ['public'] // scopes required by your BookingSync application.
]);

if (!isset($_GET['code'])) {

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

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

    unset($_SESSION['oauth2state']);
    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 user's details
        $userDetails = $provider->getUserDetails($token);

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

    } catch (Exception $e) {

        // Failed to get user details
        exit('Oh dear...');
    }

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

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

    // Unix timestamp of when the token will expire, and need refreshing
    echo $token->expires;
}

Refreshing a Token

$provider = new Bookingsync\OAuth2\Client\Provider\Bookingsync([
    'clientId'          => '{bookingsync-client-id}',
    'clientSecret'      => '{bookingsync-client-secret}',
    'redirectUri'       => 'https://example.com/callback-url'
]);

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