Introduction

Laravel Cashier Paddle provides an expressive, fluent interface to Paddle's subscription billing services. It handles almost all of the boilerplate subscription billing code you are dreading. In addition to basic subscription management, Cashier can handle: swapping subscriptions, subscription "quantities", subscription pausing, cancelation grace periods, and more.

Before digging into Cashier Paddle, we recommend you also review Paddle's concept guides and API documentation.

Upgrading Cashier

When upgrading to a new version of Cashier, it's important that you carefully review the upgrade guide.

Installation

First, install the Cashier package for Paddle using the Composer package manager:

composer require laravel/cashier-paddle

Next, you should publish the Cashier migration files using the vendor:publish Artisan command:

php artisan vendor:publish --tag="cashier-migrations"

Then, you should run your application's database migrations. The Cashier migrations will create a new customers table. In addition, new subscriptions and subscription_items tables will be created to store all of your customer's subscriptions. Lastly, a new transactions table will be created to store all of the Paddle transactions associated with your customers:

php artisan migrate

Paddle Sandbox

During local and staging development, you should register a Paddle Sandbox account. This account will give you a sandboxed environment to test and develop your applications without making actual payments. You may use Paddle's test card numbers to simulate various payment scenarios.

When using the Paddle Sandbox environment, you should set the PADDLE_SANDBOX environment variable to true within your application's .env file:

PADDLE_SANDBOX=true

After you have finished developing your application you may apply for a Paddle vendor account. Before your application is placed into production, Paddle will need to approve your application's domain.

Configuration

Billable Model

Before using Cashier, you must add the Billable trait to your user model definition. This trait provides various methods to allow you to perform common billing tasks, such as creating subscriptions and updating payment method information:

use Laravel\Paddle\Billable;
 
class User extends Authenticatable
{
    use Billable;
}

If you have billable entities that are not users, you may also add the trait to those classes:

use Illuminate\Database\Eloquent\Model;
use Laravel\Paddle\Billable;
 
class Team extends Model
{
    use Billable;
}

API Keys

Next, you should configure your Paddle keys in your application's .env file. You can retrieve your Paddle API keys from the Paddle control panel:

PADDLE_CLIENT_SIDE_TOKEN=your-paddle-client-side-token
PADDLE_API_KEY=your-paddle-api-key
PADDLE_RETAIN_KEY=your-paddle-retain-key
PADDLE_WEBHOOK_SECRET="your-paddle-webhook-secret"
PADDLE_SANDBOX=true

The PADDLE_SANDBOX environment variable should be set to true when you are using Paddle's Sandbox environment. The PADDLE_SANDBOX variable should be set to false if you are deploying your application to production and are using Paddle's live vendor environment.

The PADDLE_RETAIN_KEY is optional and should only be set if you're using Paddle with Retain.

Paddle JS

Paddle relies on its own JavaScript library to initiate the Paddle checkout widget. You can load the JavaScript library by placing the @paddleJS Blade directive right before your application layout's closing </head> tag:

<head>
    ...
 
    @paddleJS
</head>

Currency Configuration

You can specify a locale to be used when formatting money values for display on invoices. Internally, Cashier utilizes PHP's NumberFormatter class to set the currency locale:

CASHIER_CURRENCY_LOCALE=nl_BE

Overriding Default Models

You are free to extend the models used internally by Cashier by defining your own model and extending the corresponding Cashier model:

use Laravel\Paddle\Subscription as CashierSubscription;
 
class Subscription extends CashierSubscription
{
    // ...
}

After defining your model, you may instruct Cashier to use your custom model via the Laravel\Paddle\Cashier class. Typically, you should inform Cashier about your custom models in the boot method of your application's App\Providers\AppServiceProvider class:

use App\Models\Cashier\Subscription;
use App\Models\Cashier\Transaction;
 
/**
 * Bootstrap any application services.
 */
public function boot(): void
{
    Cashier::useSubscriptionModel(Subscription::class);
    Cashier::useTransactionModel(Transaction::class);
}

Quickstart

Selling Products

Offering product and subscription billing via your application can be intimidating. However, thanks to Cashier and Paddle's Checkout Overlay, you can easily build modern, robust payment integrations.

To charge customers for non-recurring, single-charge products, we'll utilize Cashier to charge customers with Paddle's Checkout Overlay, where they will provide their payment details and confirm their purchase. Once the payment has been made via the Checkout Overlay, the customer will be redirected to a success URL of your choosing within your application:

use Illuminate\Http\Request;
 
Route::get('/buy', function (Request $request) {
    $checkout = $request->user()->checkout('pri_deluxe_album')
        ->returnTo(route('dashboard'));
 
    return view('buy', ['checkout' => $checkout]);
})->name('checkout');

As you can see in the example above, we will utilize Cashier's provided checkout method to create a checkout object to present the customer the Paddle Checkout Overlay for a given "price identifier". When using Paddle, "prices" refer to defined prices for specific products.

If necessary, the checkout method will automatically create a customer in Paddle and connect that Paddle customer record to the corresponding user in your application's database. After completing the checkout session, the customer will be redirected to a dedicated success page where you can display an informational message to the customer.

In the buy view, we will include a button to display the Checkout Overlay. The paddle-button Blade component is included with Cashier Paddle; however, you may also manually render an overlay checkout:

<x-paddle-button :checkout="$checkout" class="px-8 py-4">
    Buy Product
</x-paddle-button>

Providing Meta Data to Paddle Checkout

When selling products, it's common to keep track of completed orders and purchased products via Cart and Order models defined by your own application. When redirecting customers to Paddle's Checkout Overlay to complete a purchase, you may need to provide an existing order identifier so that you can associate the completed purchase with the corresponding order when the customer is redirected back to your application.

To accomplish this, you may provide an array of custom data to the checkout method. Let's imagine that a pending Order is created within our application when a user begins the checkout process. Remember, the Cart and Order models in this example are illustrative and not provided by Cashier. You are free to implement these concepts based on the needs of your own application:

use App\Models\Cart;
use App\Models\Order;
use Illuminate\Http\Request;
 
Route::get('/cart/{cart}/checkout', function (Request $request, Cart $cart) {
    $order = Order::create([
        'cart_id' => $cart->id,
        'price_ids' => $cart->price_ids,
        'status' => 'incomplete',
    ]);
 
    $checkout = $request->user()->checkout($order->price_ids)
        ->customData(['order_id' => $order->id]);
 
    return view('billing', ['checkout' => $checkout]);
})->name('checkout');

As you can see in the example above, when a user begins the checkout process, we will provide all of the cart / order's associated Paddle price identifiers to the checkout method. Of course, your application is responsible for associating these items with the "shopping cart" or order as a customer adds them. We also provide the order's ID to the Paddle Checkout Overlay via the customData method.

Of course, you will likely want to mark the order as "complete" once the customer has finished the checkout process. To accomplish this, you may listen to the webhooks dispatched by Paddle and raised via events by Cashier to store order information in your database.

To get started, listen for the TransactionCompleted event dispatched by Cashier. Typically, you should register the event listener in the boot method of your application's AppServiceProvider:

use App\Listeners\CompleteOrder;
use Illuminate\Support\Facades\Event;
use Laravel\Paddle\Events\TransactionCompleted;
 
/**
 * Bootstrap any application services.
 */
public function boot(): void
{
    Event::listen(TransactionCompleted::class, CompleteOrder::class);
}

In this example, the CompleteOrder listener might look like the following:

namespace App\Listeners;
 
use App\Models\Order;
use Laravel\Paddle\Cashier;
use Laravel\Paddle\Events\TransactionCompleted;
 
class CompleteOrder
{
    /**
     * Handle the incoming Cashier webhook event.
     */
    public function handle(TransactionCompleted $event): void
    {
        $orderId = $event->payload['data']['custom_data']['order_id'] ?? null;
 
        $order = Order::findOrFail($orderId);
 
        $order->update(['status' => 'completed']);
    }
}

Please refer to Paddle's documentation for more information on the data contained by the transaction.completed event.

Selling Subscriptions

Offering product and subscription billing via your application can be intimidating. However, thanks to Cashier and Paddle's Checkout Overlay, you can easily build modern, robust payment integrations.

To learn how to sell subscriptions using Cashier and Paddle's Checkout Overlay, let's consider the simple scenario of a subscription service with a basic monthly (price_basic_monthly) and yearly (price_basic_yearly) plan. These two prices could be grouped under a "Basic" product (pro_basic) in our Paddle dashboard. In addition, our subscription service might offer an Expert plan as pro_expert.

First, let's discover how a customer can subscribe to our services. Of course, you can imagine the customer might click a "subscribe" button for the Basic plan on our application's pricing page. This button will invoke a Paddle Checkout Overlay for their chosen plan. To get started, let's initiate a checkout session via the checkout method:

use Illuminate\Http\Request;
 
Route::get('/subscribe', function (Request $request) {
    $checkout = $request->user()->checkout('price_basic_monthly')
        ->returnTo(route('dashboard'));
 
    return view('subscribe', ['checkout' => $checkout]);
})->name('subscribe');

In the subscribe view, we will include a button to display the Checkout Overlay. The paddle-button Blade component is included with Cashier Paddle; however, you may also manually render an overlay checkout:

<x-paddle-button :checkout="$checkout" class="px-8 py-4">
    Subscribe
</x-paddle-button>

Now, when the Subscribe button is clicked, the customer will be able to enter their payment details and initiate their subscription. To know when their subscription has actually started (since some payment methods require a few seconds to process), you should also configure Cashier's webhook handling.

Now that customers can start subscriptions, we need to restrict certain portions of our application so that only subscribed users can access them. Of course, we can always determine a user's current subscription status via the subscribed method provided by Cashier's Billable trait:

@if ($user->subscribed())
    <p>You are subscribed.</p>
@endif

We can even easily determine if a user is subscribed to specific product or price:

@if ($user->subscribedToProduct('pro_basic'))
    <p>You are subscribed to our Basic product.</p>
@endif
 
@if ($user->subscribedToPrice('price_basic_monthly'))
    <p>You are subscribed to our monthly Basic plan.</p>
@endif

Building a Subscribed Middleware

For convenience, you may wish to create a middleware which determines if the incoming request is from a subscribed user. Once this middleware has been defined, you may easily assign it to a route to prevent users that are not subscribed from accessing the route:

<?php
 
namespace App\Http\Middleware;
 
use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;
 
class Subscribed
{
    /**
     * Handle an incoming request.
     */
    public function handle(Request $request, Closure $next): Response
    {
        if (! $request->user()?->subscribed()) {
            // Redirect user to billing page and ask them to subscribe...
            return redirect('/subscribe');
        }
 
        return $next($request);
    }
}

Once the middleware has been defined, you may assign it to a route:

use App\Http\Middleware\Subscribed;
 
Route::get('/dashboard', function () {
    // ...
})->middleware([Subscribed::class]);

Allowing Customers to Manage Their Billing Plan

Of course, customers may want to change their subscription plan to another product or "tier". In our example from above, we'd want to allow the customer to change their plan from a monthly subscription to a yearly subscription. For this you'll need to implement something like a button that leads to the below route:

use Illuminate\Http\Request;
 
Route::put('/subscription/{price}/swap', function (Request $request, $price) {
    $user->subscription()->swap($price); // With "$price" being "price_basic_yearly" for this example.
 
    return redirect()->route('dashboard');
})->name('subscription.swap');

Besides swapping plans you'll also need to allow your customers to cancel their subscription. Like swapping plans, provide a button that leads to the following route:

use Illuminate\Http\Request;
 
Route::put('/subscription/cancel', function (Request $request, $price) {
    $user->subscription()->cancel();
 
    return redirect()->route('dashboard');
})->name('subscription.cancel');

And now your subscription will get canceled at the end of its billing period.

Checkout Sessions

Most operations to bill customers are performed using "checkouts" via Paddle's Checkout Overlay widget or by utilizing inline checkout.

Before processing checkout payments using Paddle, you should define your application's default payment link in your Paddle checkout settings dashboard.

Overlay Checkout

Before displaying the Checkout Overlay widget, you must generate a checkout session using Cashier. A checkout session will inform the checkout widget of the billing operation that should be performed:

use Illuminate\Http\Request;
 
Route::get('/buy', function (Request $request) {
    $checkout = $user->checkout('pri_34567')
        ->returnTo(route('dashboard'));
 
    return view('billing', ['checkout' => $checkout]);
});

Cashier includes a paddle-button Blade component. You may pass the checkout session to this component as a "prop". Then, when this button is clicked, Paddle's checkout widget will be displayed:

<x-paddle-button :checkout="$checkout" class="px-8 py-4">
    Subscribe
</x-paddle-button>

By default, this will display the widget using Paddle's default styling. You can customize the widget by adding Paddle supported attributes like the data-theme='light' attribute to the component:

<x-paddle-button :url="$payLink" class="px-8 py-4" data-theme="light">
    Subscribe
</x-paddle-button>

The Paddle checkout widget is asynchronous. Once the user creates a subscription within the widget, Paddle will send your application a webhook so that you may properly update the subscription state in your application's database. Therefore, it's important that you properly set up webhooks to accommodate for state changes from Paddle.

Manually Rendering an Overlay Checkout

You may also manually render an overlay checkout without using Laravel's built-in Blade components. To get started, generate the checkout session as demonstrated in previous examples:

use Illuminate\Http\Request;
 
Route::get('/buy', function (Request $request) {
    $checkout = $user->checkout('pri_34567')
        ->returnTo(route('dashboard'));
 
    return view('billing', ['checkout' => $checkout]);
});

Next, you may use Paddle.js to initialize the checkout. In this example, we will create a link that is assigned the paddle_button class. Paddle.js will detect this class and display the overlay checkout when the link is clicked:

<?php
$items = $checkout->getItems();
$customer = $checkout->getCustomer();
$custom = $checkout->getCustomData();
?>
 
<a
    href='#!'
    class='paddle_button'
    data-items='{!! json_encode($items) !!}'
    @if ($customer) data-customer-id='{{ $customer->paddle_id }}' @endif
    @if ($custom) data-custom-data='{{ json_encode($custom) }}' @endif
    @if ($returnUrl = $checkout->getReturnUrl()) data-success-url='{{ $returnUrl }}' @endif
>
    Buy Product
</a>

Inline Checkout

If you don't want to make use of Paddle's "overlay" style checkout widget, Paddle also provides the option to display the widget inline. While this approach does not allow you to adjust any of the checkout's HTML fields, it allows you to embed the widget within your application.

To make it easy for you to get started with inline checkout, Cashier includes a paddle-checkout Blade component. To get started, you should generate a checkout session:

use Illuminate\Http\Request;
 
Route::get('/buy', function (Request $request) {
    $checkout = $user->checkout('pri_34567')
        ->returnTo(route('dashboard'));
 
    return view('billing', ['checkout' => $checkout]);
});

Then, you may pass the checkout session to the component's checkout attribute:

<x-paddle-checkout :checkout="$checkout" class="w-full" />

To adjust the height of the inline checkout component, you may pass the height attribute to the Blade component:

<x-paddle-checkout :checkout="$checkout" class="w-full" height="500" />

Please consult Paddle's guide on Inline Checkout and available checkout settings for further details on the inline checkout's customization options.

Manually Rendering an Inline Checkout

You may also manually render an inline checkout without using Laravel's built-in Blade components. To get started, generate the checkout session as demonstrated in previous examples:

use Illuminate\Http\Request;
 
Route::get('/buy', function (Request $request) {
    $checkout = $user->checkout('pri_34567')
        ->returnTo(route('dashboard'));
 
    return view('billing', ['checkout' => $checkout]);
});

Next, you may use Paddle.js to initialize the checkout. In this example, we will demonstrate this using Alpine.js; however, you are free to modify this example for your own frontend stack:

<?php
$options = $checkout->options();
 
$options['settings']['frameTarget'] = 'paddle-checkout';
$options['settings']['frameInitialHeight'] = 366;
?>
 
<div class="paddle-checkout" x-data="{}" x-init="
    Paddle.Checkout.open(@json($options));
">
</div>

Guest Checkouts

Sometimes, you may need to create a checkout session for users that do not need an account with your application. To do so, you may use the guest method:

use Illuminate\Http\Request;
use Laravel\Paddle\Checkout;
 
Route::get('/buy', function (Request $request) {
    $checkout = Checkout::guest('pri_34567')
        ->returnTo(route('home'));
 
    return view('billing', ['checkout' => $checkout]);
});

Then, you may provide the checkout session to the Paddle button or inline checkout Blade components.

Price Previews

Paddle allows you to customize prices per currency, essentially allowing you to configure different prices for different countries. Cashier Paddle allows you to retrieve all of these prices using the previewPrices method. This method accepts the price IDs you wish to retrieve prices for:

use Laravel\Paddle\Cashier;
 
$prices = Cashier::previewPrices(['pri_123', 'pri_456']);

The currency will be determined based on the IP address of the request; however, you may optionally provide a specific country to retrieve prices for:

use Laravel\Paddle\Cashier;
 
$prices = Cashier::previewPrices(['pri_123', 'pri_456'], ['address' => [
    'country_code' => 'BE',
    'postal_code' => '1234',
]]);

After retrieving the prices you may display them however you wish:

<ul>
    @foreach ($prices as $price)
        <li>{{ $price->product['name'] }} - {{ $price->total() }}</li>
    @endforeach
</ul>

You may also display the subtotal price and tax amount separately:

<ul>
    @foreach ($prices as $price)
        <li>{{ $price->product['name'] }} - {{ $price->subtotal() }} (+ {{ $price->tax() }} tax)</li>
    @endforeach
</ul>

For more information, checkout Paddle's API documentation regarding price previews.

Customer Price Previews

If a user is already a customer and you would like to display the prices that apply to that customer, you may do so by retrieving the prices directly from the customer instance:

use App\Models\User;
 
$prices = User::find(1)->previewPrices(['pri_123', 'pri_456']);

Internally, Cashier will use the user's customer ID to retrieve the prices in their currency. So, for example, a user living in the United States will see prices in US dollars while a user in Belgium will see prices in Euros. If no matching currency can be found, the default currency of the product will be used. You can customize all prices of a product or subscription plan in the Paddle control panel.

Discounts

You may also choose to display prices after a discount. When calling the previewPrices method, you provide the discount ID via the discount_id option:

use Laravel\Paddle\Cashier;
 
$prices = Cashier::previewPrices(['pri_123', 'pri_456'], [
    'discount_id' => 'dsc_123'
]);

Then, display the calculated prices:

<ul>
    @foreach ($prices as $price)
        <li>{{ $price->product['name'] }} - {{ $price->total() }}</li>
    @endforeach
</ul>

Customers

Customer Defaults

Cashier allows you to define some useful defaults for your customers when creating checkout sessions. Setting these defaults allow you to pre-fill a customer's email address and name so that they can immediately move on to the payment portion of the checkout widget. You can set these defaults by overriding the following methods on your billable model:

/**
 * Get the customer's name to associate with Paddle.
 */
public function paddleName(): string|null
{
    return $this->name;
}
 
/**
 * Get the customer's email address to associate with Paddle.
 */
public function paddleEmail(): string|null
{
    return $this->email;
}

These defaults will be used for every action in Cashier that generates a checkout session.

Retrieving Customers

You can retrieve a customer by their Paddle Customer ID using the Cashier::findBillable method. This method will return an instance of the billable model:

use Laravel\Paddle\Cashier;
 
$user = Cashier::findBillable($customerId);

Creating Customers

Occasionally, you may wish to create a Paddle customer without beginning a subscription. You may accomplish this using the createAsCustomer method:

$customer = $user->createAsCustomer();

An instance of Laravel\Paddle\Customer is returned. Once the customer has been created in Paddle, you may begin a subscription at a later date. You may provide an optional $options array to pass in any additional customer creation parameters that are supported by the Paddle API:

$customer = $user->createAsCustomer($options);

Subscriptions

Creating Subscriptions

To create a subscription, first retrieve an instance of your billable model from your database, which will typically be an instance of App\Models\User. Once you have retrieved the model instance, you may use the subscribe method to create the model's checkout session:

use Illuminate\Http\Request;
 
Route::get('/user/subscribe', function (Request $request) {
    $checkout = $request->user()->subscribe($premium = 12345, 'default')
        ->returnTo(route('home'));
 
    return view('billing', ['checkout' => $checkout]);
});

The first argument given to the subscribe method is the specific price the user is subscribing to. This value should correspond to the price's identifier in Paddle. The returnTo method accepts a URL that your user will be redirected to after they successfully complete the checkout. The second argument passed to the subscribe method should be the internal "type" of the subscription. If your application only offers a single subscription, you might call this default or primary. This subscription type is only for internal application usage and is not meant to be displayed to users. In addition, it should not contain spaces and it should never be changed after creating the subscription.

You may also provide an array of custom metadata regarding the subscription using the customData method:

$checkout = $request->user()->subscribe($premium = 12345, 'default')
    ->customData(['key' => 'value'])
    ->returnTo(route('home'));

Once a subscription checkout session has been created, the checkout session may be provided to the paddle-button Blade component that is included with Cashier Paddle:

<x-paddle-button :checkout="$checkout" class="px-8 py-4">
    Subscribe
</x-paddle-button>

After the user has finished their checkout, a subscription_created webhook will be dispatched from Paddle. Cashier will receive this webhook and setup the subscription for your customer. In order to make sure all webhooks are properly received and handled by your application, ensure you have properly setup webhook handling.

Checking Subscription Status

Once a user is subscribed to your application, you may check their subscription status using a variety of convenient methods. First, the subscribed method returns true if the user has a valid subscription, even if the subscription is currently within its trial period:

if ($user->subscribed()) {
    // ...
}

If your application offers multiple subscriptions, you may specify the subscription when invoking the subscribed method:

if ($user->subscribed('default')) {
    // ...
}

The subscribed method also makes a great candidate for a route middleware, allowing you to filter access to routes and controllers based on the user's subscription status:

<?php
 
namespace App\Http\Middleware;
 
use Closure;
use Illuminate\Http\Request;
use Symfony\Component\HttpFoundation\Response;
 
class EnsureUserIsSubscribed
{
    /**
     * Handle an incoming request.
     *
     * @param  \Closure(\Illuminate\Http\Request): (\Symfony\Component\HttpFoundation\Response)  $next
     */
    public function handle(Request $request, Closure $next): Response
    {
        if ($request->user() && ! $request->user()->subscribed()) {
            // This user is not a paying customer...
            return redirect('/billing');
        }
 
        return $next($request);
    }
}

If you would like to determine if a user is still within their trial period, you may use the onTrial method. This method can be useful for determining if you should display a warning to the user that they are still on their trial period:

if ($user->subscription()->onTrial()) {
    // ...
}

The subscribedToPrice method may be used to determine if the user is subscribed to a given plan based on a given Paddle price ID. In this example, we will determine if the user's default subscription is actively subscribed to the monthly price:

if ($user->subscribedToPrice($monthly = 'pri_123', 'default')) {
    // ...
}

The recurring method may be used to determine if the user is currently on an active subscription and is no longer within their trial period or on a grace period:

if ($user->subscription()->recurring()) {
    // ...
}

Canceled Subscription Status

To determine if the user was once an active subscriber but has canceled their subscription, you may use the canceled method:

if ($user->subscription()->canceled()) {
    // ...
}

You may also determine if a user has canceled their subscription, but are still on their "grace period" until the subscription fully expires. For example, if a user cancels a subscription on March 5th that was originally scheduled to expire on March 10th, the user is on their "grace period" until March 10th. In addition, the subscribed method will still return true during this time:

if ($user->subscription()->onGracePeriod()) {
    // ...
}

Past Due Status

If a payment fails for a subscription, it will be marked as past_due. When your subscription is in this state it will not be active until the customer has updated their payment information. You may determine if a subscription is past due using the pastDue method on the subscription instance:

if ($user->subscription()->pastDue()) {
    // ...
}

When a subscription is past due, you should instruct the user to update their payment information.

If you would like subscriptions to still be considered valid when they are past_due, you may use the keepPastDueSubscriptionsActive method provided by Cashier. Typically, this method should be called in the register method of your AppServiceProvider:

use Laravel\Paddle\Cashier;
 
/**
 * Register any application services.
 */
public function register(): void
{
    Cashier::keepPastDueSubscriptionsActive();
}

Subscription Scopes

Most subscription states are also available as query scopes so that you may easily query your database for subscriptions that are in a given state:

// Get all valid subscriptions...
$subscriptions = Subscription::query()->valid()->get();
 
// Get all of the canceled subscriptions for a user...
$subscriptions = $user->subscriptions()->canceled()->get();

A complete list of available scopes is available below:

Subscription::query()->valid();
Subscription::query()->onTrial();
Subscription::query()->expiredTrial();
Subscription::query()->notOnTrial();
Subscription::query()->active();
Subscription::query()->recurring();
Subscription::query()->pastDue();
Subscription::query()->paused();
Subscription::query()->notPaused();
Subscription::query()->onPausedGracePeriod();
Subscription::query()->notOnPausedGracePeriod();
Subscription::query()->canceled();
Subscription::query()->notCanceled();
Subscription::query()->onGracePeriod();
Subscription::query()->notOnGracePeriod();

Subscription Single Charges

Subscription single charges allow you to charge subscribers with a one-time charge on top of their subscriptions. You must provide one or multiple price ID's when invoking the charge method:

// Charge a single price...
$response = $user->subscription()->charge('pri_123');
 
// Charge multiple prices at once...
$response = $user->subscription()->charge(['pri_123', 'pri_456']);

The charge method will not actually charge the customer until the next billing interval of their subscription. If you would like to bill the customer immediately, you may use the chargeAndInvoice method instead:

$response = $user->subscription()->chargeAndInvoice('pri_123');

Updating Payment Information

Paddle always saves a payment method per subscription. If you want to update the default payment method for a subscription, you should redirect your customer to Paddle's hosted payment method update page using the redirectToUpdatePaymentMethod method on the subscription model:

use Illuminate\Http\Request;
 
Route::get('/update-payment-method', function (Request $request) {
    $user = $request->user();
 
    return $user->subscription()->redirectToUpdatePaymentMethod();
});

When a user has finished updating their information, a subscription_updated webhook will be dispatched by Paddle and the subscription details will be updated in your application's database.

Changing Plans

After a user has subscribed to your application, they may occasionally want to change to a new subscription plan. To update the subscription plan for a user, you should pass the Paddle price's identifier to the subscription's swap method:

use App\Models\User;
 
$user = User::find(1);
 
$user->subscription()->swap($premium = 'pri_456');

If you would like to swap plans and immediately invoice the user instead of waiting for their next billing cycle, you may use the swapAndInvoice method:

$user = User::find(1);
 
$user->subscription()->swapAndInvoice($premium = 'pri_456');

Prorations

By default, Paddle prorates charges when swapping between plans. The noProrate method may be used to update the subscriptions without prorating the charges:

$user->subscription('default')->noProrate()->swap($premium = 'pri_456');

If you would like to disable proration and invoice customers immediately, you may use the swapAndInvoice method in combination with noProrate:

$user->subscription('default')->noProrate()->swapAndInvoice($premium = 'pri_456');

Or, to not bill your customer for a subscription change, you may utilize the doNotBill method:

$user->subscription('default')->doNotBill()->swap($premium = 'pri_456');

For more information on Paddle's proration policies, please consult Paddle's proration documentation.

Subscription Quantity

Sometimes subscriptions are affected by "quantity". For example, a project management application might charge $10 per month per project. To easily increment or decrement your subscription's quantity, use the incrementQuantity and decrementQuantity methods:

$user = User::find(1);
 
$user->subscription()->incrementQuantity();
 
// Add five to the subscription's current quantity...
$user->subscription()->incrementQuantity(5);
 
$user->subscription()->decrementQuantity();
 
// Subtract five from the subscription's current quantity...
$user->subscription()->decrementQuantity(5);

Alternatively, you may set a specific quantity using the updateQuantity method:

$user->subscription()->updateQuantity(10);

The noProrate method may be used to update the subscription's quantity without prorating the charges:

$user->subscription()->noProrate()->updateQuantity(10);

Quantities for Subscriptions With Multiple Products

If your subscription is a subscription with multiple products, you should pass the ID of the price whose quantity you wish to increment or decrement as the second argument to the increment / decrement methods:

$user->subscription()->incrementQuantity(1, 'price_chat');

Subscriptions With Multiple Products

Subscription with multiple products allow you to assign multiple billing products to a single subscription. For example, imagine you are building a customer service "helpdesk" application that has a base subscription price of $10 per month but offers a live chat add-on product for an additional $15 per month.

When creating subscription checkout sessions, you may specify multiple products for a given subscription by passing an array of prices as the first argument to the subscribe method:

use Illuminate\Http\Request;
 
Route::post('/user/subscribe', function (Request $request) {
    $checkout = $request->user()->subscribe([
        'price_monthly',
        'price_chat',
    ]);
 
    return view('billing', ['checkout' => $checkout]);
});

In the example above, the customer will have two prices attached to their default subscription. Both prices will be charged on their respective billing intervals. If necessary, you may pass an associative array of key / value pairs to indicate a specific quantity for each price:

$user = User::find(1);
 
$checkout = $user->subscribe('default', ['price_monthly', 'price_chat' => 5]);

If you would like to add another price to an existing subscription, you must use the subscription's swap method. When invoking the swap method, you should also include the subscription's current prices and quantities as well:

$user = User::find(1);
 
$user->subscription()->swap(['price_chat', 'price_original' => 2]);

The example above will add the new price, but the customer will not be billed for it until their next billing cycle. If you would like to bill the customer immediately you may use the swapAndInvoice method:

$user->subscription()->swapAndInvoice(['price_chat', 'price_original' => 2]);

You may remove prices from subscriptions using the swap method and omitting the price you want to remove:

$user->subscription()->swap(['price_original' => 2]);

Multiple Subscriptions

Paddle allows your customers to have multiple subscriptions simultaneously. For example, you may run a gym that offers a swimming subscription and a weight-lifting subscription, and each subscription may have different pricing. Of course, customers should be able to subscribe to either or both plans.

When your application creates subscriptions, you may provide the type of the subscription to the subscribe method as the second argument. The type may be any string that represents the type of subscription the user is initiating:

use Illuminate\Http\Request;
 
Route::post('/swimming/subscribe', function (Request $request) {
    $checkout = $request->user()->subscribe($swimmingMonthly = 'pri_123', 'swimming');
 
    return view('billing', ['checkout' => $checkout]);
});

In this example, we initiated a monthly swimming subscription for the customer. However, they may want to swap to a yearly subscription at a later time. When adjusting the customer's subscription, we can simply swap the price on the swimming subscription:

$user->subscription('swimming')->swap($swimmingYearly = 'pri_456');

Of course, you may also cancel the subscription entirely:

$user->subscription('swimming')->cancel();

Pausing Subscriptions

To pause a subscription, call the pause method on the user's subscription:

$user->subscription()->pause();

When a subscription is paused, Cashier will automatically set the paused_at column in your database. This column is used to determine when the paused method should begin returning true. For example, if a customer pauses a subscription on March 1st, but the subscription was not scheduled to recur until March 5th, the paused method will continue to return false until March 5th. This is because a user is typically allowed to continue using an application until the end of their billing cycle.

By default, pausing happens at the next billing interval so the customer can use the remainder of the period they paid for. If you want to pause a subscription immediately, you may use the pauseNow method:

$user->subscription()->pauseNow();

Using the pauseUntil method, you can pause the subscription until a specific moment in time:

$user->subscription()->pauseUntil(now()->addMonth());

Or, you may use the pauseNowUntil method to immediately pause the subscription until a given point in time:

$user->subscription()->pauseNowUntil(now()->addMonth());

You may determine if a user has paused their subscription but are still on their "grace period" using the onPausedGracePeriod method:

if ($user->subscription()->onPausedGracePeriod()) {
    // ...
}

To resume a paused subscription, you may invoke the resume method on the subscription:

$user->subscription()->resume();

Canceling Subscriptions

To cancel a subscription, call the cancel method on the user's subscription:

$user->subscription()->cancel();

When a subscription is canceled, Cashier will automatically set the ends_at column in your database. This column is used to determine when the subscribed method should begin returning false. For example, if a customer cancels a subscription on March 1st, but the subscription was not scheduled to end until March 5th, the subscribed method will continue to return true until March 5th. This is done because a user is typically allowed to continue using an application until the end of their billing cycle.

You may determine if a user has canceled their subscription but are still on their "grace period" using the onGracePeriod method:

if ($user->subscription()->onGracePeriod()) {
    // ...
}

If you wish to cancel a subscription immediately, you may call the cancelNow method on the subscription:

$user->subscription()->cancelNow();

To stop a subscription on its grace period from canceling, you may invoke the stopCancelation method:

$user->subscription()->stopCancelation();

Subscription Trials

With Payment Method Up Front

If you would like to offer trial periods to your customers while still collecting payment method information up front, you should use set a trial time in the Paddle dashboard on the price your customer is subscribing to. Then, initiate the checkout session as normal:

use Illuminate\Http\Request;
 
Route::get('/user/subscribe', function (Request $request) {
    $checkout = $request->user()->subscribe('pri_monthly')
                ->returnTo(route('home'));
 
    return view('billing', ['checkout' => $checkout]);
});

When your application receives the subscription_created event, Cashier will set the trial period ending date on the subscription record within your application's database as well as instruct Paddle to not begin billing the customer until after this date.

You may determine if the user is within their trial period using either the onTrial method of the user instance or the onTrial method of the subscription instance. The two examples below are equivalent:

if ($user->onTrial()) {
    // ...
}
 
if ($user->subscription()->onTrial()) {
    // ...
}

To determine if an existing trial has expired, you may use the hasExpiredTrial methods:

if ($user->hasExpiredTrial()) {
    // ...
}
 
if ($user->subscription()->hasExpiredTrial()) {
    // ...
}

To determine if a user is on trial for a specific subscription type, you may provide the type to the onTrial or hasExpiredTrial methods:

if ($user->onTrial('default')) {
    // ...
}
 
if ($user->hasExpiredTrial('default')) {
    // ...
}

Without Payment Method Up Front

If you would like to offer trial periods without collecting the user's payment method information up front, you may set the trial_ends_at column on the customer record attached to your user to your desired trial ending date. This is typically done during user registration:

use App\Models\User;
 
$user = User::create([
    // ...
]);
 
$user->createAsCustomer([
    'trial_ends_at' => now()->addDays(10)
]);

Cashier refers to this type of trial as a "generic trial", since it is not attached to any existing subscription. The onTrial method on the User instance will return true if the current date is not past the value of trial_ends_at:

if ($user->onTrial()) {
    // User is within their trial period...
}

Once you are ready to create an actual subscription for the user, you may use the subscribe method as usual:

use Illuminate\Http\Request;
 
Route::get('/user/subscribe', function (Request $request) {
    $checkout = $user->subscribe('pri_monthly')
        ->returnTo(route('home'));
 
    return view('billing', ['checkout' => $checkout]);
});

To retrieve the user's trial ending date, you may use the trialEndsAt method. This method will return a Carbon date instance if a user is on a trial or null if they aren't. You may also pass an optional subscription type parameter if you would like to get the trial ending date for a specific subscription other than the default one:

if ($user->onTrial('default')) {
    $trialEndsAt = $user->trialEndsAt();
}

You may use the onGenericTrial method if you wish to know specifically that the user is within their "generic" trial period and has not created an actual subscription yet:

if ($user->onGenericTrial()) {
    // User is within their "generic" trial period...
}

Extend or Activate a Trial

You can extend an existing trial period on a subscription by invoking the extendTrial method and specifying the moment in time that the trial should end:

$user->subscription()->extendTrial(now()->addDays(5));

Or, you may immediately activate a subscription by ending its trial by calling the activate method on the subscription:

$user->subscription()->activate();

Handling Paddle Webhooks

Paddle can notify your application of a variety of events via webhooks. By default, a route that points to Cashier's webhook controller is registered by the Cashier service provider. This controller will handle all incoming webhook requests.

By default, this controller will automatically handle canceling subscriptions that have too many failed charges, subscription updates, and payment method changes; however, as we'll soon discover, you can extend this controller to handle any Paddle webhook event you like.

To ensure your application can handle Paddle webhooks, be sure to configure the webhook URL in the Paddle control panel. By default, Cashier's webhook controller responds to the /paddle/webhook URL path. The full list of all webhooks you should enable in the Paddle control panel are:

• Customer Updated
• Transaction Completed
• Transaction Updated
• Subscription Created
• Subscription Updated
• Subscription Paused
• Subscription Canceled

Webhooks and CSRF Protection

Since Paddle webhooks need to bypass Laravel's CSRF protection, you should ensure that Laravel does not attempt to verify the CSRF token for incoming Paddle webhooks. To accomplish this, you should exclude paddle/* from CSRF protection in your application's bootstrap/app.php file:

->withMiddleware(function (Middleware $middleware) {
    $middleware->validateCsrfTokens(except: [
        'paddle/*',
    ]);
})

Webhooks and Local Development

For Paddle to be able to send your application webhooks during local development, you will need to expose your application via a site sharing service such as Ngrok or Expose. If you are developing your application locally using Laravel Sail, you may use Sail's site sharing command.

Defining Webhook Event Handlers

Cashier automatically handles subscription cancelation on failed charges and other common Paddle webhooks. However, if you have additional webhook events you would like to handle, you may do so by listening to the following events that are dispatched by Cashier:

• Laravel\Paddle\Events\WebhookReceived
• Laravel\Paddle\Events\WebhookHandled

Both events contain the full payload of the Paddle webhook. For example, if you wish to handle the transaction.billed webhook, you may register a listener that will handle the event:

<?php
 
namespace App\Listeners;
 
use Laravel\Paddle\Events\WebhookReceived;
 
class PaddleEventListener
{
    /**
     * Handle received Paddle webhooks.
     */
    public function handle(WebhookReceived $event): void
    {
        if ($event->payload['event_type'] === 'transaction.billed') {
            // Handle the incoming event...
        }
    }
}

Cashier also emit events dedicated to the type of the received webhook. In addition to the full payload from Paddle, they also contain the relevant models that were used to process the webhook such as the billable model, the subscription, or the receipt:

You can also override the default, built-in webhook route by defining the CASHIER_WEBHOOK environment variable in your application's .env file. This value should be the full URL to your webhook route and needs to match the URL set in your Paddle control panel:

CASHIER_WEBHOOK=https://example.com/my-paddle-webhook-url

Verifying Webhook Signatures

To secure your webhooks, you may use Paddle's webhook signatures. For convenience, Cashier automatically includes a middleware which validates that the incoming Paddle webhook request is valid.

To enable webhook verification, ensure that the PADDLE_WEBHOOK_SECRET environment variable is defined in your application's .env file. The webhook secret may be retrieved from your Paddle account dashboard.

Single Charges

Charging for Products

If you would like to initiate a product purchase for a customer, you may use the checkout method on a billable model instance to generate a checkout session for the purchase. The checkout method accepts one or multiple price ID's. If necessary, an associative array may be used to provide the quantity of the product that is being purchased:

use Illuminate\Http\Request;
 
Route::get('/buy', function (Request $request) {
    $checkout = $request->user()->checkout(['pri_tshirt', 'pri_socks' => 5]);
 
    return view('buy', ['checkout' => $checkout]);
});

After generating the checkout session, you may use Cashier's provided paddle-button Blade component to allow the user to view the Paddle checkout widget and complete the purchase:

<x-paddle-button :checkout="$checkout" class="px-8 py-4">
    Buy
</x-paddle-button>

A checkout session has a customData method, allowing you to pass any custom data you wish to the underlying transaction creation. Please consult the Paddle documentation to learn more about the options available to you when passing custom data:

$checkout = $user->checkout('pri_tshirt')
    ->customData([
        'custom_option' => $value,
    ]);

Refunding Transactions

Refunding transactions will return the refunded amount to your customer's payment method that was used at the time of purchase. If you need to refund a Paddle purchase, you may use the refund method on a Cashier\Paddle\Transaction model. This method accepts a reason as the first argument, one or more price ID's to refund with optional amounts as an associative array. You may retrieve the transactions for a given billable model using the transactions method.

For example, imagine we want to refund a specific transaction for prices pri_123 and pri_456. We want to fully refund pri_123, but only refund two dollars for pri_456:

use App\Models\User;
 
$user = User::find(1);
 
$transaction = $user->transactions()->first();
 
$response = $transaction->refund('Accidental charge', [
    'pri_123', // Fully refund this price...
    'pri_456' => 200, // Only partially refund this price...
]);

The example above refunds specific line items in a transaction. If you want to refund the entire transaction, simply provide a reason:

$response = $transaction->refund('Accidental charge');

For more information on refunds, please consult Paddle's refund documentation.

Crediting Transactions

Just like refunding, you can also credit transactions. Crediting transactions will add the funds to the customer's balance so it may be used for future purchases. Crediting transactions can only be done for manually-collected transactions and not for automatically-collected transactions (like subscriptions) since Paddle handles subscription credits automatically:

$transaction = $user->transactions()->first();
 
// Credit a specific line item fully...
$response = $transaction->credit('Compensation', 'pri_123');

For more info, see Paddle's documentation on crediting.

Transactions

You may easily retrieve an array of a billable model's transactions via the transactions property:

use App\Models\User;
 
$user = User::find(1);
 
$transactions = $user->transactions;

Transactions represent payments for your products and purchases and are accompanied by invoices. Only completed transactions are stored in your application's database.

When listing the transactions for a customer, you may use the transaction instance's methods to display the relevant payment information. For example, you may wish to list every transaction in a table, allowing the user to easily download any of the invoices:

<table>
    @foreach ($transactions as $transaction)
        <tr>
            <td>{{ $transaction->billed_at->toFormattedDateString() }}</td>
            <td>{{ $transaction->total() }}</td>
            <td>{{ $transaction->tax() }}</td>
            <td><a href="{{ route('download-invoice', $transaction->id) }}" target="_blank">Download</a></td>
        </tr>
    @endforeach
</table>

The download-invoice route may look like the following:

use Illuminate\Http\Request;
use Laravel\Paddle\Transaction;
 
Route::get('/download-invoice/{transaction}', function (Request $request, Transaction $transaction) {
    return $transaction->redirectToInvoicePdf();
})->name('download-invoice');

Past and Upcoming Payments

You may use the lastPayment and nextPayment methods to retrieve and display a customer's past or upcoming payments for recurring subscriptions:

use App\Models\User;
 
$user = User::find(1);
 
$subscription = $user->subscription();
 
$lastPayment = $subscription->lastPayment();
$nextPayment = $subscription->nextPayment();

Both of these methods will return an instance of Laravel\Paddle\Payment; however, lastPayment will return null when transactions have not been synced by webhooks yet, while nextPayment will return null when the billing cycle has ended (such as when a subscription has been canceled):

Next payment: {{ $nextPayment->amount() }} due on {{ $nextPayment->date()->format('d/m/Y') }}

Testing

While testing, you should manually test your billing flow to make sure your integration works as expected.

For automated tests, including those executed within a CI environment, you may use Laravel's HTTP Client to fake HTTP calls made to Paddle. Although this does not test the actual responses from Paddle, it does provide a way to test your application without actually calling Paddle's API.
