Authorization Code Flow

session_start();

$provider = new League\OAuth2\Client\Provider\Lightspeed([
    'clientId'                => LIGHTSPEED_CLIENT_ID,
    'clientSecret'            => LIGHTSPEED_CLIENT_SECRET,
    'redirectUri'             => LIGHTSPEED_REDIRECT_URI,
]);

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

    // If we don't have an authorization code then get one
    $authUrl = $provider->getAuthorizationUrl([
        'scope' => ['employee:all', '...', '...'],
    ]);
    $_SESSION['oauth2state'] = $provider->getState();
    
    echo '<a href="'.$authUrl.'">Log in with LightSpeed!</a>';
    exit;

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

    unset($_SESSION['oauth2state']);
    echo 'Invalid state.';
    exit;

}

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

try {

    // We got an access token, let's now get the Account ID and sale details
    $client = $provider->getResourceOwner($token);
    $merchantos = $provider->merchantosApi($token, $client->getId());

    $clientId = $client->getId();
    $sale = $merchantos->getSale(1);

    echo '<pre>';
    print_r($client); echo '<br>';
    print_r($sale); echo '<br>';
    echo '</pre>';

} catch (Exception $e) {
