Laravel AWS SNS Listener

Laravel integration package for receiving AWS SNS webhooks with signature validation, typed payload mapping, and Laravel event dispatch.

What This Package Does

• Registers an SNS webhook route in your Laravel app.
• Validates incoming SNS signatures with AWS certificates.
• Maps SNS payloads to typed message entities.
• Handles subscription confirmation for expected topics.
• Dispatches Laravel events for generic and provider-specific notifications.

Installation

composer require sinemacula/laravel-aws-sns-listener

The service provider is auto-discovered by Laravel.

Configuration

Publish the config file:

php artisan vendor:publish --provider="SineMacula\Aws\Sns\SnsServiceProvider"

Key options (config/aws.php):

• aws.sns.route: webhook path for SNS callbacks (default: /hooks/sns).
• aws.sns.topics: expected topic ARNs for subscription confirmation checks.

Environment examples:

AWS_SNS_ROUTE=/hooks/sns
AWS_SNS_TOPICS=arn:aws:sns:eu-west-1:123456789012:orders,arn:aws:sns:eu-west-1:123456789012:alerts

To disable auto route registration, set aws.sns.route to false in config.

Request Flow

1. SNS posts to the configured route.
2. VerifySnsSignature validates the message signature.
3. MessageFactory maps the payload to a typed message.
4. SnsController handles the message and dispatches events.

For SubscriptionConfirmation, the package confirms the subscription URL only when the topic is registered in aws.sns.topics.

Dispatched Events

• SineMacula\Aws\Sns\Events\SubscriptionConfirmed
• SineMacula\Aws\Sns\Events\NotificationReceived
• SineMacula\Aws\Sns\Events\SNSNotificationReceived
• SineMacula\Aws\Sns\Events\S3NotificationReceived
• SineMacula\Aws\Sns\Events\SesNotificationReceived
• SineMacula\Aws\Sns\Events\CloudWatchNotificationReceived

Each event carries a typed message object implementing the matching contract interface from SineMacula\Aws\Sns\Entities\Messages\Contracts.

Example Listener

<?php

namespace App\Listeners;

use SineMacula\Aws\Sns\Events\S3NotificationReceived;

final class HandleS3Notification
{
    public function handle(S3NotificationReceived $event): void
    {
        foreach ($event->getNotification()->getRecords() as $record) {
            // Process each S3 record.
        }
    }
}
