README

Handle PayPal webhooks in Laravel php framework.

Installation

You can install the package via composer:

composer require "ankurk91/laravel-paypal-webhooks"

The service provider will automatically register itself.

You must publish the config file with:

php artisan vendor:publish --provider="Ankurk91\PayPalWebhooks\PayPalWebhooksServiceProvider"

Next, you must publish the migration with:

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

After the migration has been published you can create the webhook_calls table by running the migrations:

php artisan migrate

Next, for routing, add this route (guest) to your routes/web.php

Route::paypalWebhooks('/webhooks/paypal');

Behind the scenes this will register a POST route to a controller provided by this package. Next, you must add that route to the except array of your VerifyCsrfToken middleware:

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

It is recommended to set up a queue worker to precess the incoming webhooks.

Setup PayPal account

Login to PayPal developer dashboard
Create a new Application (recommended)
Create a new Webhook under the newly created application
Enter your webhook URL. 💡 You can use ngrok for local development
Choose events to be tracked (Don't select all), for example:
- Checkout order approved
You will see a Webhook ID upon saving
Specify this webhook ID in your .env like

PAYPAL_WEBHOOK_ID=6U272633NC098611R

This webhook ID will be used to verify the incoming request Signature.

Troubleshoot

When using ngrok during development, you must update your APP_URL to match with ngrok vanity URL, for example:

APP_URL=https://af59-111-93-41-42.ngrok-free.app

You must verify that your webhook URL is publicly accessible by visiting the URL on terminal

curl -X POST https://af59-111-93-41-42.ngrok-free.app/webhooks/paypal

Usage

There are 2 ways to handle incoming webhooks via this package.

1 - Handling webhook requests using jobs

If you want to do something when a specific event type comes in; you can define a job for that event. Here's an example of such job:

<?php

namespace App\Jobs\Webhook\PayPal;

use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\SerializesModels;
use Spatie\WebhookClient\Models\WebhookCall;

class CheckoutOrderApprovedJob implements ShouldQueue
{
    use SerializesModels;

    public function __construct(protected WebhookCall $webhookCall)
    {
        //
    }

    public function handle()
    {
        $message = $this->webhookCall->payload['resource'];
            
        // todo do something with $message['id']        
    }
}

After having created your job you must register it at the jobs array in the config/paypal-webhooks.php config file. The key must be in lowercase and dots must be replaced by _. The value must be a fully qualified classname.

<?php

return [
     'jobs' => [
          'checkout_order_approved' => \App\Jobs\Webhook\PayPal\CheckoutOrderApprovedJob::class,
     ],
];

2 - Handling webhook requests using events and listeners

Instead of queueing jobs to perform some work when a webhook request comes in, you can opt to listen to the events this package will fire. Whenever a matching request hits your app, the package will fire a paypal-webhooks::<name-of-the-event> event.

The payload of the events will be the instance of WebhookCall that was created for the incoming request.

You can listen for such event by registering the listener in your EventServiceProvider class.

protected $listen = [
    'paypal-webhooks::payment_order_cancelled' => [
        App\Listeners\PayPal\PaymentOrderCancelledListener::class,
    ],
];

Here's an example of such listener class:

<?php

namespace App\Listeners\PayPal;

use Illuminate\Contracts\Queue\ShouldQueue;
use Spatie\WebhookClient\Models\WebhookCall;

class PaymentOrderCancelledListener implements ShouldQueue
{
    public function handle(WebhookCall $webhookCall)
    {
        $message = $webhookCall->payload['resource'];
               
        // todo do something with $message        
    }
}

Pruning old webhooks (opt-in but recommended)

Update your app/Console/Kernel.php file like:

use Illuminate\Database\Console\PruneCommand;
use Spatie\WebhookClient\Models\WebhookCall;

$schedule->command(PruneCommand::class, [
            '--model' => [WebhookCall::class]
        ])
        ->onOneServer()
        ->daily()
        ->description('Prune webhook_calls.');

This will delete records older than 30 days, you can modify this duration by publishing this config file.

php artisan vendor:publish --provider="Spatie\WebhookClient\WebhookClientServiceProvider" --tag="webhook-client-config"
