README

A general-purpose PHP SDK for the Fenerum API. Use FenerumClient in any PHP application. Laravel integration is optional.

Source: github.com/kevin4845/laravel-fenerum

Requirements and installation

PHP 8.2 or newer
ext-json
Guzzle 7.9 or newer (installed with this package)

The test suite has been run on PHP 8.4.14. The Laravel integration has been tested on Laravel 13.39.0. PHP 8.2, PHP 8.3, Laravel 11, and Laravel 12 have not been tested in this environment.

Install the latest stable release:

composer require kevin4845/laravel-fenerum:^0.9

For the latest development branch instead:

composer require kevin4845/laravel-fenerum:dev-main

illuminate/support is not required for the plain PHP client.

Plain PHP

Pass your Fenerum API token. The client sends Authorization: Token <token> and X-Client-System.

use Kevin4845\LaravelFenerum\FenerumClient;

$token = getenv('FENERUM_TOKEN');
if (!is_string($token) || $token === '') {
    throw new RuntimeException('Set FENERUM_TOKEN.');
}

$client = FenerumClient::create(
    token: $token,
    clientSystem: 'MyApp',
);

$account = $client->accounts()->get('CUST001');

get() takes the account code. clientSystem is required. The default API origin is https://app.fenerum.com.

Laravel

Package discovery registers Kevin4845\LaravelFenerum\Laravel\FenerumServiceProvider and the Fenerum facade. Set FENERUM_TOKEN; FENERUM_CLIENT_SYSTEM defaults to Laravel. The client is resolved on first use, not during package discovery.

use Kevin4845\LaravelFenerum\Laravel\Fenerum;

$account = Fenerum::accounts()->get('CUST001');

The same call works through the Fenerum alias. You can also inject Kevin4845\LaravelFenerum\FenerumClient.

Optional settings are available in config/fenerum.php: FENERUM_USER, FENERUM_BASE_URL, FENERUM_TIMEOUT, FENERUM_MAX_RETRIES, and FENERUM_MAX_RETRY_DELAY. Publish the configuration with:

php artisan vendor:publish --tag=fenerum-config

Features

Resource clients for accounts, subscriptions, invoices, plans, products, exports, webhooks, and other operations documented in docs/api-coverage.md.
Paginated lists return Kevin4845\LaravelFenerum\Support\Page with count, next, previous, and results.
HTTP 429 responses for GET, PUT, and DELETE are retried when Retry-After is usable, with up to 2 additional attempts and 60 seconds of total sleep by default. POST, PATCH, network failures, and other status codes are not retried.
Parse webhook events with webhookParser()->parse($rawBody), or Fenerum::webhookParser() when using Laravel.

Limitations

PATCH /api/v1/invoices/{uuid}/ and POST /api/v1/expense-documents/upload/ are not implemented because their request contracts are undocumented or unclear.
Webhook bodies can be parsed, but signature verification is not implemented.
The API coverage report is based on the OpenAPI schema retrieved on 2026-10-28; it does not mean every operation has been verified against a live Fenerum account.

Development and license

Run the checks with:

composer check

This runs Composer validation, PHPCS, PHPStan level 8, and PHPUnit. Tests mock HTTP requests and do not call Fenerum.

The package declares the MIT license in composer.json.
