MailgunLogger

This package allows a laravel app to receive Mailgun webhooks. It makes use of Spatie's Webhook Client Package to capture the webhooks. You then can queue jobs to process the webhooks as you see fit.

It also has a service to retrieve stored messages through the api.

Installation

Install the package using composer:

composer require aleahy/mailgun-logger

The service provider should autoregister.

You will need your mailgun signing secret in your .env file.

MAILGUN_SIGNING_SECRET=ABC123

If you want to define jobs to respond to the webhooks, you will need to publish the config file.

Publish the config file using

php artisan vendor:publish --provider="Aleahy\MailgunLogger\MailgunLoggerServiceProvider" --tag="config"

You can then define your jobs in the jobs section of the mailgun-logger config file.

/**
 * If you want to process a webhook, create a job to handle the type of event.
 * Keys must be one of the event types found at
 * https://documentation.mailgun.com/en/latest/api-events.html#event-types
 */
'jobs' => [
    'failed' => HandleFailedJob::class
],

Make sure the key for each job you define is one of the event types defined in the Mailgun API.

You will need the migrations from the Spatie\WebhookClient Package to store the webhook calls.

If you haven't already done so, publish them using:

php artisan vendor:publish --provider="Spatie\WebhookClient\WebhookClientServiceProvider" --tag="migrations"

and run the migration:

php artisan migrate

Routing

Define a route for incoming mailgun events in your routes/web.php file using the Route macro mailgunWebhooks:

# routes/web.php
Route::mailgunWebhooks('webhooks/mailgun');

This will register a POST route to a controller in this package.

You will also need to bypass CSRF token checking for this route by adding it to the VerifyCsrfToken middleware.

protected $except = [
    'webhooks/mailgun',
];

Usage

Responding to Webhooks

Create a laravel job class that extends Spatie\WebhookClient\Jobs\ProcessWebhookJob to be run when the webhook is received.

As the parent class receives the webhook in the constructor, the payload can be access by $this->webhookCall->payload.

If you decide not to extend Spatie\WebhookClient\Jobs\ProcessWebhookJob, then make sure it can receive the webhook in the constructor. It is also important that the job is queueable so that Mailgun can receive a response immediately.

An example is shown below:

use Spatie\WebhookClient\Jobs\ProcessWebhookJob;

class HandleFailedJob extends ProcessWebhookJob
{
    public function handle()
    {
        // The payload of the webhook call with `$this->webhookCall->payload`
    }
}

Once the job class is created, just add it to the jobs array in the mailgun-logger config file. The key is the event type, as listed in the Mailgun API docs, and the value is the job class name.

'jobs' => [
    'failed' => HandleFailedJob::class
],

Getting Stored Messages

Some of the mailgun webhooks contain a url to the stored message. You can access the contents of the message using the MailgunService class.

$message = MailgunService::get($url);

This will return an associative array containing various forms of the message, under keys such as stripped-text, body-html, stripped-html.

You can also get the raw MIME message.

$mimeMessage = MailgunService::getMime($url);

This also returns an associative array which contains the mime data under the key body-mime.

Upgrading from 0.3 to 1

Version 1.0 requires PHP 8.0 and also has upgraded Spatie\WebhookClient to version 3.1.7.
The migrations for this package has changed, so in order to upgrade, you must add the following migration:

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class AddColumnsToWebhookCalls extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up(): void
    {
        Schema::table('webhook_calls', function (Blueprint $table) {
            $table->string('url')->nullable();
            $table->json('headers')->nullable();
            $table->json('payload')->change();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down(): void
    {
        Schema::table('webhook_calls', function (Blueprint $table) {
            $table->dropColumn('url');
            $table->dropColumn('headers');
            $table->text('payload')->change();
        });
    }
}

Credits

Much of this package was influenced by binary-cats/laravel-mailgun-webhooks.

Thanks also to Spatie for creating such amazing packages, including their Webhook Client Package which this package makes use of.
