Adding New Payment Provider

If your favorite payment provider is not supported out of the box, you can easily implement it in SaaSykit.

SaaSykit offers a simple payment interface (contract) that you can implement in your application to support any payment provider you want.

Here is a list of the steps you need to follow to implement a new payment provider:

1. Create a new class that implements the App\Services\PaymentProviders\PaymentProviderInterface interface. (You can find an example of how to implement the contract in the App\Services\PaymentProviders\Stripe\StripeProvider class).
2. Register your payment provider in app/Providers/AppServiceProvider.php.

   $this->app->tag([
       StripeProvider::class,
       PaddleProvider::class,
       LemonSqueezyProvider::class,
       YourNewPaymentProvider::class,    
   ], 'payment-providers');
3. Add your new payment method in the database seeders in database/seeders/PaymentProvidersSeeder.php (see the existing seeder definitions there for examples).
4. If your payment provider send webhook events, then you will need to add a controller to handle these events. You can find an example of how to handle Stripe webhook events in the App\Http\Controllers\PaymentProviders\StripeController class.
5. (optional) You might want to implement a settings/credentials page for your new payment provider on the admin panel. You can find an example of how to implement the settings page in the app/Filament/Admin/Resources/PaymentProviderResource/Pages/StripeSettings.php class.

That's it! You have now implemented a new payment provider in SaaSykit. You can now enable it in the admin panel and start accepting payments from your customers using your new payment provider.
