Whop Laravel

[!WARNING] This package is in active development and is not yet ready for production use. The public API may change at any time before version 1.0.0 is released. Please do not depend on it in production projects until a stable release is published.

Laravel package for the Whop PHP SDK — auto-wires the WhopApiClient and WebhookVerifier from configuration, ships a signature-verifying middleware, an overridable webhook route + handler, and two artisan commands.

What this is

A thin integration layer over the framework-agnostic devmatchable/whop-php-sdk. It does four things:

• Binds the SDK's Matchable\Whop\WhopApiClient and Matchable\Whop\Webhook\WebhookVerifier as container singletons, driven by the whop config.
• Registers a whop.signature middleware alias that verifies the Standard Webhooks signature on incoming requests and stashes the verified raw body on the request.
• Auto-mounts a webhook route at whop.webhook_path whose default handler dispatches a WhopWebhookReceived event — zero-config consumers only write a listener.
• Exposes whop:check and whop:webhook:verify artisan commands for setup validation and signature debugging.

The package owns only framework wiring. API logic, DTOs, and signature math live in the SDK and are not duplicated here.

Requirements

• PHP 8.4+
• Laravel 11, 12, or 13
• devmatchable/whop-php-sdk ^0.0.1

Installation

composer require devmatchable/whop-laravel

Laravel package auto-discovery registers WhopServiceProvider and the Whop facade alias automatically — no edits to bootstrap/providers.php or config/app.php.

Publish the config file:

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

Set the required environment variables:

WHOP_API_KEY=...
WHOP_WEBHOOK_SECRET=whsec_...
WHOP_BUSINESS_ID=biz_...
# Optional overrides
# WHOP_BASE_URL=https://sandbox-api.whop.com/api/v1
# WHOP_WEBHOOK_PATH=/_whop/webhook
# WHOP_HTTP_CLIENT=
# WHOP_REGISTER_ROUTES=true

Quick start

Resolve the WhopApiClient and call any SDK resource. Constructor injection is the recommended path:

use Matchable\Whop\WhopApiClient;

final readonly class CompanyLookup
{
    public function __construct(
        private WhopApiClient $whop,
    ) {
    }

    public function fetch(string $companyId): void
    {
        $company = $this->whop->companies->get($companyId);
        // ...
    }
}

The Whop facade resolves the same singleton. SDK resources are exposed as public readonly properties on WhopApiClient, so reach them through the facade root:

use Matchable\Whop\Package\Facades\Whop;

$company = Whop::getFacadeRoot()->companies->get($companyId);

(The facade is most useful for IDE autocompletion via its @mixin WhopApiClient hint; in application code, prefer constructor injection.)

Configuration reference

All keys live under config/whop.php and map 1:1 to environment variables:

Receiving webhooks — the auto-route

By default the package mounts a POST route at whop.webhook_path with the whop.signature middleware applied and WhopWebhookController as the action. The controller verifies the signature, decodes the JSON body, and hands off to the bound WhopWebhookHandlerInterface. The default handler dispatches a WhopWebhookReceived event, so zero-config integration is just a listener:

use Matchable\Whop\Package\Events\WhopWebhookReceived;

final class HandleWhopWebhook
{
    public function handle(WhopWebhookReceived $event): void
    {
        // $event->payload    — decoded webhook JSON (array<string, mixed>)
        // $event->rawPayload — the verified raw request body
    }
}

Register it in your EventServiceProvider:

protected $listen = [
    \Matchable\Whop\Package\Events\WhopWebhookReceived::class => [
        \App\Listeners\HandleWhopWebhook::class,
    ],
];

The controller responds with 204 No Content on success, 401 Unauthorized on an invalid signature, and 400 Bad Request on a body that is not decodable JSON.

Receiving webhooks — custom route + middleware

Disable the auto-route and wire your own action. The whop.signature middleware alias is registered unconditionally, so you keep signature verification:

WHOP_REGISTER_ROUTES=false

// routes/web.php (or routes/api.php)
use App\Http\Controllers\MyWhopWebhookController;
use Illuminate\Support\Facades\Route;

Route::post('/webhooks/whop', MyWhopWebhookController::class)
    ->middleware('whop.signature');

Laravel 12 CSRF note: consumer-defined POST routes in the web group are CSRF-protected by default — Whop's request will be rejected with a 419 before whop.signature runs. To accept Whop webhooks at a web-group path, exclude it in bootstrap/app.php:

->withMiddleware(function (Middleware $middleware) {
    $middleware->validateCsrfTokens(except: ['webhooks/whop']);
})

Or register the route under routes/api.php — the api group has no CSRF. The auto-mounted /_whop/webhook route is registered as a standalone route outside the web group, so this only applies to consumer-defined routes.

Read the verified body from the request attributes — the middleware stashes it under the VerifyWhopSignature::VERIFIED_BODY_ATTRIBUTE constant ('whop.raw_body'):

use Illuminate\Http\Request;
use Matchable\Whop\Package\Http\Middleware\VerifyWhopSignature;

final class MyWhopWebhookController
{
    public function __invoke(Request $request)
    {
        $rawBody = (string) $request->attributes->get(
            VerifyWhopSignature::VERIFIED_BODY_ATTRIBUTE,
        );
        $payload = json_decode($rawBody, associative: true);
        // ...
    }
}

Overriding the webhook handler

The default handler is bound as WhopWebhookHandlerInterface => EventDispatchingWebhookHandler. Three documented override paths:

1. Rebind the interface to your own implementation:

   // app/Providers/AppServiceProvider.php
   use App\Whop\MyWebhookHandler;
   use Matchable\Whop\Package\Webhook\WhopWebhookHandlerInterface;
   
   public function register(): void
   {
       $this->app->bind(WhopWebhookHandlerInterface::class, MyWebhookHandler::class);
   }
   

2. Extend EventDispatchingWebhookHandler and override handle():

   use Matchable\Whop\Package\Webhook\EventDispatchingWebhookHandler;
   
   final class MyWebhookHandler extends EventDispatchingWebhookHandler
   {
       public function handle(array $payload, string $rawPayload): void
       {
           // pre-processing
           parent::handle($payload, $rawPayload);
           // post-processing
       }
   }
   

3. Decorate the bound instance with the container's extend:

   use Matchable\Whop\Package\Webhook\WhopWebhookHandlerInterface;
   
   $this->app->extend(
       WhopWebhookHandlerInterface::class,
       fn (WhopWebhookHandlerInterface $inner) => new LoggingWebhookHandler($inner),
   );
   

Artisan commands

# Verify config + perform a probe GET against the Whop API.
php artisan whop:check

whop:check exits with code 1 if any required key (api_key, webhook_secret, business_id, base_url) is missing. With config in place it issues a live probe against /plans?company_id={WHOP_BUSINESS_ID} to confirm the credentials reach Whop.

# Re-verify a captured webhook against the configured (or supplied) secret.
php artisan whop:webhook:verify \
    --payload-file=/tmp/whop-body.json \
    --id=msg_... \
    --timestamp=1714234567 \
    --signature='v1,...'

Quality gates

composer cs        # Pint dry-run
composer cs:fix    # Pint apply
composer stan      # Larastan at level max
composer test      # Pest (unit + integration)
composer mutate    # pest --mutate --covered-only --everything --min=97

CI (.github/workflows/ci.yml) runs the matrix PHP {8.4, 8.5} × Laravel {11, 12} × {highest, lowest} dependencies. Pint, Larastan, and mutation testing run on the canonical leg (PHP 8.4 / Laravel 12 / highest); Pest runs on every leg. Larastan runs at level: max with no baseline — fix the code, do not weaken the level.

Laravel 13 is supported by the package's require constraints, but the CI matrix does not yet include a Laravel 13 leg — adding one requires bumping the pestphp/pest/pestphp/pest-plugin-laravel dev dependencies to ^4.0 (Pest v3 caps at Laravel 12). Track that as its own change.

Versioning

Pre-1.0. The public API may change between minor releases until 1.0.0. Pin a specific version in production rather than a range until then.
