This package integrates the new recommended package of xeroapi/xero-php-oauth2 using the Oauth 2.0 spec with Laravel.
You can install this package via composer using the following command:
composer require webfox/laravel-xero-oauth2
The package will automatically register itself.
You should add your Xero keys to your .env file using the following keys:
XERO_CLIENT_ID=
XERO_CLIENT_SECRET=
When setting up the application in Xero ensure your redirect url is https://{your-domain}/xero/auth/callback
You can publish the configuration file with:
php artisan vendor:publish --provider="Webfox\Xero\XeroServiceProvider" --tag="config"
You'll want to set the scopes required for your application in the config file.
The default set of scopes are openid
, email
, profile
, offline_access
, and accounting.settings
.
You can see all available scopes on the official Xero documentation.
This package registers two bindings into the service container you'll be interested in:
\XeroAPI\XeroPHP\Api\AccountingApi::class
this is the main api for Xero - see the xeroapi/xero-php-oauth2 docs for usage. When you first resolve this dependency if the stored credentials are expired it will automatically refresh the token.Webfox\Xero\OauthCredentialManager
this is the credential manager - The Accounting API requires we pass through a tenant ID on each request, this class is how you'd access that. This is also where we can get information about the authenticating user. See below for an example.
app\Http\Controllers\XeroController.php
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Webfox\Xero\OauthCredentialManager;
class XeroController extends Controller
{
public function index(Request $request, OauthCredentialManager $xeroCredentials)
{
try {
// Check if we've got any stored credentials
if ($xeroCredentials->exists()) {
/*
* We have stored credentials so we can resolve the AccountingApi,
* If we were sure we already had some stored credentials then we could just resolve this through the controller
* But since we use this route for the initial authentication we cannot be sure!
*/
$xero = resolve(\XeroAPI\XeroPHP\Api\AccountingApi::class);
$organisationName = $xero->getOrganisations($xeroCredentials->getTenantId())->getOrganisations()[0]->getName();
$user = $xeroCredentials->getUser();
$username = "{$user['given_name']} {$user['family_name']} ({$user['username']})";
}
} catch (\throwable $e) {
// This can happen if the credentials have been revoked or there is an error with the organisation (e.g. it's expired)
$error = $e->getMessage();
}
return view('xero', [
'connected' => $xeroCredentials->exists(),
'error' => $error ?? null,
'organisationName' => $organisationName ?? null,
'username' => $username ?? null
]);
}
}

Version 1 of this package stored the credentials in the cache, while this worked for most, some users clear their cache on deployment of a new version of their app, this also restricted an app to only one set of credentials per codebase.
Version 2 swaps this out for an interface and provides a default FileStore
implementation which stores the credentials on
/storage/framework/xero.json
you can switch out the credential store (e.g. for your own UserStore
if you wanted to store
the credentials against your user) in one of two ways
- If it's a simple store and Laravel can automatically resolve your bindings, simply change the
xero.credential_store
config key to point to your new implementation. - If it requires more advanced logic (e.g. using the current user to retrieve the credentials) then you can rebind this
in your
AppServiceProvider
or a Middleware e.g.
$this->app->bind(OauthCredentialManager::class, function(Application $app) {
return new UserStorageProvider(
\Auth::user(), // Storage Mechanism
$app->make('session.store'), // Used for storing/retrieving oauth 2 "state" for redirects
$app->make(\Webfox\Xero\Oauth2Provider::class) // Used for getting redirect url and refreshing token
);
});
On your application in the Xero developer portal create a webhook to get your webhook key.
You can then add this to your .env file as
XERO_WEBHOOK_KEY=...
You can then setup a controller to handle your webhook and inject \Webfox\Xero\Webhook
e.g.
<?php
namespace App\Http\Controllers;
use Webfox\Xero\Webhook;
use Illuminate\Http\Request;
use Illuminate\Http\Response;
use XeroApi\XeroPHP\Models\Accounting\Contact;
use XeroApi\XeroPHP\Models\Accounting\Invoice;
class XeroWebhookController extends Controller
{
public function __invoke(Request $request, Webhook $webhook)
{
// The following lines are required for Xero's 'itent to receive' validation
if (!$webhook->validate($request->header('x-xero-signature'))) {
// We can't use abort here, since Xero expects no response body
return response('', Response::HTTP_UNAUTHORIZED);
}
// A single webhook trigger can contain multiple events, so we must loop over them
foreach ($webhook->getEvents() as $event) {
if ($event->getEventType() === 'CREATE' && $event->getEventCategory() === 'INVOICE') {
$this->invoiceCreated($request, $event->getResource());
} elseif ($event->getEventType() === 'CREATE' && $event->getEventCategory() === 'CONTACT') {
$this->contactCreated($request, $event->getResource());
} elseif ($event->getEventType() === 'UPDATE' && $event->getEventCategory() === 'INVOICE') {
$this->invoiceUpdated($request, $event->getResource());
} elseif ($event->getEventType() === 'UPDATE' && $event->getEventCategory() === 'CONTACT') {
$this->contactUpdated($request, $event->getResource());
}
}
return response('', Response::HTTP_OK);
}
protected function invoiceCreated(Request $request, Invoice $invoice)
{
}
protected function contactCreated(Request $request, Contact $contact)
{
}
protected function invoiceUpdated(Request $request, Invoice $invoice)
{
}
protected function contactUpdated(Request $request, Contact $contact)
{
}
}
This package is simply a bridge so you don't have to deal with the Oauth2 gymnastics in Laravel.
Once you've have an instance of \XeroAPI\XeroPHP\Api\AccountingApi::class you're dealing directly with Xero's api library.
The XeroAPI PHP Oauth2 App repository has this list of examples of implementing calls to the API: e.g. invoice creation etc.
