README
This package provides Square OAuth 2.0 support for the PHP League's OAuth 2.0 Client.
Installation
To install, use composer:
composer require wheniwork/oauth2-square
Usage
Usage is the same as The League's OAuth client, using Wheniwork\OAuth2\Client\Provider\Square
as the provider.
To make requests against the Square staging server, pass 'debug' => true
as part of the initial configuration options.
Authorization Code Flow
$provider = new Wheniwork\OAuth2\Client\Provider\Square([ 'clientId' => '{square-client-id}', 'clientSecret' => '{square-client-secret}', 'redirectUri' => 'https://example.com/callback-url' ]); if (!isset($_GET['code'])) { // If we don't have an authorization code then get one $authUrl = $provider->getAuthorizationUrl(); $_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->firstName); } 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; }
Refreshing a Token
Square does not provide refresh tokens. Instead, an access token can be "renewed"
up to 15 days after it expires. To accomdate this, the Square provider provides
an additional grant, RenewToken
.
$provider = new Wheniwork\OAuth2\Client\Provider\Square([ 'clientId' => '{square-client-id}', 'clientSecret' => '{square-client-secret}', 'redirectUri' => 'https://example.com/callback-url' ]); $token = $provider->getAccessToken('renew_token', ['access_token' => $accessToken]);
This grant can also be used by injecting the AccessToken
instance directly,
instead of providing a parameter to getAccessToken
:
$grant = new Wheniwork\OAuth2\Client\Grant\RenewToken($token); $token = $provider->getAccessToken($grant);
