# Subscription boilerplate (optional)

Most of the time, when adding billing to your application, all you need is a Subscription model attach to a User or a Team based on what entity you want to bill.

Therefore this package offers some useful stubs that you can publish to your application using the following command:

php artisan kanuu:publish

This will publish the following files in your application:

• A Subscription model.
• A create_subscriptions_table migration.
• A SubscriptionFactory.
• A HasSubscription trait to add to your billable entity (e.g. User or Team). By default it will be added to your User model.
• A KanuuServiceProvider implementing all the webhook listeners we need. It will also be registered in your config/app.php file.

Additionally, it will add the following routes to your routes/web file if they don't already exists:

• Kanuu::redirectRoute()->name('kanuu.redirect').
• Kanuu::webhookRoute()->name('webhooks.paddle') — And it will add 'webhooks/*' to the $except array of the VerifyCsrfToken middleware.

By default, the subscription boilerplate will assume our billable entity is the User model. If you want to subscribe teams instead of users, you can provide the --team option to the kanuu:publish command.

php artisan kanuu:publish --team

Note that, with or without that option, you can always tweak the migration and the model to attach it to whatever model you want. This is just a boilerplate to get you started but don’t let that restrict your creativity.

# Summary using Paddle's webhooks

This page provides a quick checklist allowing you to add billing to your Laravel applications using Paddle's webhooks in 5 minutes. Let's go!

1. Setup Paddle and Kanuu. This requires no code. Follow these quick steps:

   • 1. Setup Paddle
   • 2. Setup Kanuu

2. Install the package.

   composer require kanuu-io/kanuu-laravel
   

3. Add some environment variables. Add your Kanuu API key and your Paddle public key to your .env file. It should look like this:

   KANUU_API_KEY="sn71bn8tsZKY0oMtbqRqbnV4FYRCwRK21SVqcIfA"
   PADDLE_PUBLIC_KEY="-----BEGIN PUBLIC KEY-----
   MIGeMA0GCSqGSIb3DQEBAQUAA4GMADCBiAKBgFCTPPt2xm/rFTN2FAp9R4Lc3gzr

   jmN/Z5OEgY3c9J87A9psTDAQABEAAQ==
   -----END PUBLIC KEY-----"
   

4. Publish the subscription boilerplate. Don't forget to tweak the Subscription model and its migration to fit your need.

   php artisan kanuu:publish
   
   # Or, when charging teams instead of users:
   php artisan kanuu:publish --team
   

5. Add your webhook URL to Paddle. In your Paddle's account, go to "Developer Tools > Alerts / Webhooks" and add your application's base URL followed by /webhooks/paddle as a webhook URL.

6. Add a button that redirects to Kanuu. In your settings page, add a button that securely redirects your customers to Kanuu so they can manage their subscription.

   <a href="{{ route('kanuu.redirect', $user) }}" class="...">
       Manage your subscription
   </a>
   

That's it!

Happy billing! 💸
