Receiver

Receiver is a drop-in webhook handling library for Laravel.

Receiver gives you a consistent, expressive way to receive, verify, and handle incoming webhooks in your Laravel app. Point a route at a controller, call three methods, and you're done.

Out of the box, Receiver supports:

Provider	Driver
GitHub	github
HubSpot	hubspot
Mailchimp Marketing	mailchimp
Paddle Billing	paddle
Postmark	postmark
SendGrid Events	sendgrid
Shopify	shopify
Slack Events API	slack
Stripe	stripe
Twilio	twilio

Any other webhook source can be added with a custom provider.

Installation

Requires PHP ^8.2 and Laravel 10+.

composer require hotmeteor/receiver

Note: The Stripe provider requires stripe/stripe-php:

composer require stripe/stripe-php

Configuration

Each provider reads its secret from config/services.php. Add an entry for each source you intend to receive from.

Most providers use the same shape:

'github'   => ['webhook_secret' => env('GITHUB_WEBHOOK_SECRET')],
'hubspot'  => ['webhook_secret' => env('HUBSPOT_WEBHOOK_SECRET')],
'paddle'   => ['webhook_secret' => env('PADDLE_WEBHOOK_SECRET')],
'shopify'  => ['webhook_secret' => env('SHOPIFY_WEBHOOK_SECRET')],
'slack'    => ['webhook_secret' => env('SLACK_WEBHOOK_SECRET')],
'stripe'   => ['webhook_secret' => env('STRIPE_WEBHOOK_SECRET')],
'twilio'   => ['webhook_secret' => env('TWILIO_AUTH_TOKEN')],

Mailchimp — Mailchimp Marketing webhooks are verified via a secret you embed in your webhook URL (?secret=...). Configure the same value here so Receiver can compare it:

'mailchimp' => ['webhook_secret' => env('MAILCHIMP_WEBHOOK_SECRET')],

SendGrid — Signature verification is opt-in. Set webhook_secret to the PEM-format public key found in the SendGrid dashboard under Settings → Mail Settings → Event Webhook. Leave it empty to accept all requests without verification.

'sendgrid' => ['webhook_secret' => env('SENDGRID_WEBHOOK_PUBLIC_KEY', '')],

Postmark — Postmark supports several verification strategies. Configure which ones to use under the webhook key:

'postmark' => [
    'token' => env('POSTMARK_TOKEN'),
    'webhook' => [
        // One or more of: 'auth', 'headers', 'ips'
        'verification_types' => ['headers', 'ips'],

        // Header name => expected value pairs (used with 'headers')
        'headers' => [
            'X-Custom-Header' => env('POSTMARK_WEBHOOK_HEADER'),
        ],

        // Allowed source IPs (used with 'ips')
        // https://postmarkapp.com/support/article/800-ips-for-firewalls#webhooks
        'ips' => [
            '3.134.147.250',
            '50.31.156.6',
            '50.31.156.77',
            '18.217.206.57',
        ],
    ],
],

Postmark verification_type	Description
auth	HTTP Basic Auth via Auth::onceBasic()
headers	Validates that specific request headers match expected values
ips	Validates that the request originates from an allowed IP

If verification_types is empty or not set, all Postmark requests are accepted without verification.

Receiving Webhooks

Single provider

Create a controller and route for each webhook source, then call driver(), receive(), and ok():

<?php

namespace App\Http\Controllers\Webhooks;

use Illuminate\Http\Request;
use Receiver\Facades\Receiver;

class StripeWebhookController extends Controller
{
    public function store(Request $request)
    {
        return Receiver::driver('stripe')
            ->receive($request)
            ->ok();
    }
}

• driver() — selects the provider and reads its config
• receive() — verifies the signature and maps the event
• ok() — dispatches matched handlers and returns a 200 response

Multiple providers

If you'd rather handle all webhooks through a single controller, use a {provider} route parameter:

// routes/web.php
Route::post('/webhooks/{provider}', [WebhookController::class, 'store'])
    ->withoutMiddleware(\Illuminate\Foundation\Http\Middleware\ValidateCsrfToken::class);

<?php

namespace App\Http\Controllers\Webhooks;

use Illuminate\Http\Request;
use Receiver\Facades\Receiver;

class WebhookController extends Controller
{
    public function store(Request $request, string $provider)
    {
        return Receiver::driver($provider)
            ->receive($request)
            ->ok();
    }
}

Or use the included ReceivesWebhooks trait, which provides this exact store() method for you:

<?php

namespace App\Http\Controllers\Webhooks;

use Receiver\ReceivesWebhooks;

class WebhookController extends Controller
{
    use ReceivesWebhooks;
}

Fallbacks

Receiver silently ignores events it has no handler for. If you'd like to do something with unhandled events, add a fallback() callback before ok():

use Receiver\Providers\Webhook;

return Receiver::driver($provider)
    ->receive($request)
    ->fallback(function (Webhook $webhook) {
        Log::info('Unhandled webhook', ['event' => $webhook->getEvent()]);
    })
    ->ok();

Handling Webhooks

Once a webhook is received, Receiver looks for a handler class that matches the event and dispatches it. Handlers live in App\Http\Handlers\{Driver}\ by default. If no matching handler is found the webhook is silently ignored and a 200 is returned.

Handler naming

The handler class name is derived from the event name — all non-alphanumeric characters are treated as word separators, then converted to StudlyCase:

Event name	Handler class
customer.created	CustomerCreated
subscription_activated	SubscriptionActivated
orders_created	OrdersCreated
invoice.payment_failed	InvoicePaymentFailed

For example, Stripe's customer.created event dispatches App\Http\Handlers\Stripe\CustomerCreated.

Each handler receives the $event name and the $data array, and must use the Dispatchable trait:

<?php

namespace App\Http\Handlers\Stripe;

use Illuminate\Foundation\Bus\Dispatchable;

class CustomerCreated
{
    use Dispatchable;

    public function __construct(
        public string $event,
        public array $data,
    ) {}

    public function handle(): void
    {
        // Your code here
    }
}

Queueing handlers

Because Receiver calls dispatch() on each handler, making a handler queued is as simple as implementing ShouldQueue:

<?php

namespace App\Http\Handlers\Stripe;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;

class CustomerCreated implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;

    public function __construct(
        public string $event,
        public array $data,
    ) {}

    public function handle(): void
    {
        // Your code here
    }
}

See the Laravel queue documentation for full details.

Extending Receiver

A provider is a PHP class that tells Receiver how to extract the event name, the payload data, and optionally how to verify the request's authenticity.

Generating a provider

The quickest way to scaffold a new provider is with the receiver:make Artisan command:

# Basic provider
php artisan receiver:make Mailgun

# With signature verification scaffolded
php artisan receiver:make Mailgun --verified

The generated class is placed in App\Http\Receivers. Once created, register the driver in your AppServiceProvider:

public function boot(): void
{
    app('receiver')->extend('mailgun', function () {
        return new \App\Http\Receivers\MailgunProvider(
            config('services.mailgun.webhook_secret')
        );
    });
}

Defining getEvent() and getData()

Implement getEvent() to return the event name. Optionally implement getData() to return the event payload — by default it returns $request->all().

<?php

namespace App\Http\Receivers;

use Illuminate\Http\Request;
use Receiver\Providers\AbstractProvider;

class MailgunProvider extends AbstractProvider
{
    public function getEvent(Request $request): string|array
    {
        return $request->input('event-data.event');
    }

    public function getData(Request $request): array
    {
        return $request->input('event-data', []);
    }
}

Securing webhooks

Implement a verify() method that returns true if the request is authentic, or false to reject it with a 401 response:

public function verify(Request $request): bool
{
    $signature = $request->header('X-Mailgun-Signature');
    $expected = hash_hmac('sha256', $request->getContent(), $this->secret);

    return hash_equals($expected, (string) $signature);
}

The signing secret from config/services.{driver}.webhook_secret is available as $this->secret.

Handshakes

Some services send a verification request when a webhook URL is first registered. Implement handshake() to respond to it:

public function handshake(Request $request): array
{
    return ['challenge' => $request->input('challenge')];
}

When handshake() returns a non-empty array, Receiver responds immediately with that payload and skips normal event handling. When it returns an empty array, Receiver processes the request normally.

Multiple events per request

Some services batch multiple events into a single request. Return an ['event_name' => $eventData] array from getEvent() and Receiver will dispatch a separate handler for each entry:

public function getEvent(Request $request): string|array
{
    $events = [];

    foreach (json_decode($request->getContent(), true) as $event) {
        $type = $event['type'] ?? null;
        if ($type && ! isset($events[$type])) {
            $events[$type] = $event;
        }
    }

    return $events;
}

Creating a community provider

If you're building a reusable provider package to share, add the --provider flag to also generate a companion ServiceProvider that registers the driver automatically:

php artisan receiver:make Mailgun --provider
php artisan receiver:make Mailgun --verified --provider

This generates:

• app/Http/Receivers/MailgunProvider.php — your provider class
• app/Providers/MailgunReceiverServiceProvider.php — auto-registers the driver via Receiver::extend()

To support Laravel package auto-discovery, add the service provider to your package's composer.json:

{
    "extra": {
        "laravel": {
            "providers": [
                "YourVendor\\YourPackage\\MailgunReceiverServiceProvider"
            ]
        }
    }
}

Users who install your package will have the driver available immediately, with no manual registration required.
