Xero Provider for OAuth 2.0 Client

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

Installation

To install, use composer:

$ composer require calcinai/oauth2-xero

Usage

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

Authorization Code Flow

session_start();
 
$provider = new \Calcinai\OAuth2\Client\Provider\Xero([
    'clientId'          => '{xero-client-id}',
    'clientSecret'      => '{xero-client-secret}',
    'redirectUri'       => 'https://example.com/callback-url',
]);
 
if (!isset($_GET['code'])) {

    // If we don't have an authorization code then get one
    $authUrl = $provider->getAuthorizationUrl([
        'scope' => 'openid email profile accounting.transactions'
    ]);

    $_SESSION['oauth2state'] = $provider->getState();
    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']
    ]);


    //If you added the openid/profile scopes you can access the authorizing user's identity.
    $identity = $provider->getResourceOwner($token);
    print_r($identity);

    //Get the tenants that this user is authorized to access
    $tenants = $provider->getTenants($token);
    print_r($tenants);
}

You can then store the token and use it to make requests against the api to the desired tenants

Scopes

OAuth scopes, indicating which parts of the Xero organisation you'd like your app to be able to access. The complete list of scopes can be found here.

$provider = new \Calcinai\OAuth2\Client\Provider\Xero([
   'clientId'          => '{xero-client-id}',
   'clientSecret'      => '{xero-client-secret}',
   'redirectUri'       => 'https://example.com/callback-url',
]);
   
$authUrl = $provider->$provider->getAuthorizationUrl([
   'scope' => 'bankfeeds accounting.transactions'
]);

Refreshing a token

$newAccessToken = $provider->getAccessToken('refresh_token', [
    'refresh_token' => $existingAccessToken->getRefreshToken()
]);

Testing

$ ./vendor/bin/phpunit
