Introduction
Laravel Cashier provides an expressive, fluent interface to Stripe's subscription billing services. It handles almost all of the boilerplate subscription billing code you are dreading writing. In addition to basic subscription management, Cashier can handle coupons, swapping subscription, subscription "quantities", cancellation grace periods, and even generate invoice PDFs.
Configuration
Composer
First, add the Cashier package to your
composer.json
file and run the
composer update
command:
"laravel/cashier": "~5.0" (For Stripe SDK ~2.0, and Stripe APIs on 2015-02-18 version and later)
"laravel/cashier": "~4.0" (For Stripe APIs on 2015-02-18 version and later)
"laravel/cashier": "~3.0" (For Stripe APIs up to and including 2015-02-16 version)
Service Provider
Next, register the
Laravel\Cashier\CashierServiceProvider
service provider in your
app
configuration file.
Migration
Before using Cashier, we'll need to add several columns
to your database. Don't worry, you can use the
cashier:table
Artisan command to create a
migration to add the necessary column. For example, to
add the column to the users table run the command:
php artisan cashier:table users
.
Once the migration has been created, simply run the
migrate
command.
Model Setup
Next, add the Billable
trait and appropriate
date mutators to your model definition:
use Laravel\Cashier\Billable;
use Laravel\Cashier\Contracts\Billable as BillableContract;
class User extends Model implements BillableContract
{
use Billable;
protected $dates = ['trial_ends_at', 'subscription_ends_at'];
}
Adding the columns to your model's $dates
property will instruct Eloquent to return the columns as
Carbon / DateTime instances instead of raw strings.
Stripe Key
Finally, set your Stripe key in your
services.php
configuration file:
'stripe' => [
'model' => 'User',
'secret' => env('STRIPE_API_SECRET'),
],
Subscriptions
Creating Subscriptions
To create a subscription, first retrieve an instance of
your billable model, which typically will be an instance
of App\User
. Once you have retrieved the
model instance, you may use the
subscription
method to manage the model's
subscription:
$user = User::find(1);
$user->subscription('monthly')->create($creditCardToken);
The create
method will automatically create
the Stripe subscription, as well as update your database
with Stripe customer ID and other relevant billing
information. If your plan has a trial configured in
Stripe, the trial end date will also automatically be
set on the user record.
If you want to implement trial periods, but are managing the trials entirely within your application instead of defining them within Stripe, you must manually set the trial end date:
$user->trial_ends_at = Carbon::now()->addDays(14);
$user->save();
Additional User Details
If you would like to specify additional customer details,
you may do so by passing them as the second argument to
the create
method:
$user->subscription('monthly')->create($creditCardToken, [
'email' => $email, 'description' => 'Our First Customer'
]);
To learn more about the additional fields supported by Stripe, check out Stripe's documentation on customer creation.
Coupons
If you would like to apply a coupon when creating the
subscription, you may use the withCoupon
method:
$user->subscription('monthly')
->withCoupon('code')
->create($creditCardToken);
Checking Subscription Status
Once a user is subscribed to your application, you may
easily check their subscription status using a variety
of convenient methods. First, the
subscribed
method returns true
if the user has an active subscription, even if the
subscription is currently within its trial period:
if ($user->subscribed()) {
//
}
The subscribed
method also makes a great
candidate for a route
middleware, allowing you to filter access to
routes and controllers based on the user's subscription
status:
public function handle($request, Closure $next)
{
if ($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 displaying a
warning to the user that they are still on their trial
period:
if ($user->onTrial()) {
//
}
The onPlan
method may be used to determine
if the user is subscribed to a given plan based on its
Stripe ID:
if ($user->onPlan('monthly')) {
//
}
Cancelled Subscription Status
To determine if the user was once an active subscriber,
but has cancelled their subscription, you may use the
cancelled
method:
if ($user->cancelled()) {
//
}
You may also determine if a user has cancelled their
subscription, but are still on their "grace
period" until the subscription fully expires. For
example, if a user cancels a subscription on March 5th
that was originally scheduled to expire on March 10th,
the user is on their "grace period" until
March 10th. Note that the subscribed
method
still returns true
during this time.
if ($user->onGracePeriod()) {
//
}
The everSubscribed
method may be used to
determine if the user has ever subscribed to a plan in
your application:
if ($user->everSubscribed()) {
//
}
Changing Plans
After a user is subscribed to your application, they may
occasionally want to change to a new subscription plan.
To swap a user to a new subscription, use the
swap
method. For example, we may easily
switch a user to the premium
subscription:
$user = App\User::find(1);
$user->subscription('premium')->swap();
If the user is on trial, the trial period will be
maintained. Also, if a "quantity" exists for
the subscription, that quantity will also be maintained.
When swapping plans, you may also use the
prorate
method to indicate that the charges
should be pro-rated. In addition, you may use the
swapAndInvoice
method to immediately
invoice the user for the plan change:
$user->subscription('premium')
->prorate()
->swapAndInvoice();
Subscription Quantity
Sometimes subscriptions are affected by
"quantity". For example, your application
might charge $10 per month per user on
an account. To easily increment or decrement your
subscription quantity, use the increment
and decrement
methods:
$user = User::find(1);
$user->subscription()->increment();
// Add five to the subscription's current quantity...
$user->subscription()->increment(5);
$user->subscription()->decrement();
// Subtract five to the subscription's current quantity...
$user->subscription()->decrement(5);
Alternatively, you may set a specific quantity using the
updateQuantity
method:
$user->subscription()->updateQuantity(10);
For more information on subscription quantities, consult the Stripe documentation.
Subscription Taxes
With Cashier, it's easy to provide the
tax_percent
value sent to Stripe. To
specify the tax percentage a user pays on a
subscription, implement the getTaxPercent
method on your billable model, and return a numeric
value between 0 and 100, with no more than 2 decimal
places.
public function getTaxPercent() {
return 20;
}
This enables you to apply a tax rate on a model-by-model basis, which may be helpful for a user base that spans multiple countries.
Cancelling Subscriptions
To cancel a subscription, simply call the
cancel
method on the user's
subscription:
$user->subscription()->cancel();
When a subscription is cancelled, Cashier will
automatically set the subscription_ends_at
column in your database. This column is used to know
when the subscribed
method should begin
returning false
. For example, if a customer
cancels a subscription on March 1st, but the
subscription was not scheduled to end until March 5th,
the subscribed
method will continue to
return true
until March 5th.
You may determine if a user has cancelled their
subscription but are still on their "grace
period" using the onGracePeriod
method:
if ($user->onGracePeriod()) {
//
}
Resuming Subscriptions
If a user has cancelled their subscription and you wish
to resume it, use the resume
method:
$user->subscription('monthly')->resume($creditCardToken);
If the user cancels a subscription and then resumes that subscription before the subscription has fully expired, they will not be billed immediately. Instead, their subscription will simply be re-activated, and they will be billed on the original billing cycle.
Handling Stripe Webhooks
Failed Subscriptions
What if a customer's credit card expires? No worries - Cashier includes a Webhook controller that can easily cancel the customer's subscription for you. Just point a route to the controller:
Route::post('stripe/webhook', '\Laravel\Cashier\WebhookController@handleWebhook');
That's it! Failed payments will be captured and handled by the controller. The controller will cancel the customer's subscription when Stripe determines the subscription has failed (normally after three failed payment attempts). Don't forget: you will need to configure the webhook URI in your Stripe control panel settings.
Since Stripe webhooks need to bypass Laravel's CSRF
verification, be sure to list the URI as an
exception in your VerifyCsrfToken
middleware:
protected $except = [
'stripe/*',
];
Other Webhooks
If you have additional Stripe webhook events you would
like to handle, simply extend the Webhook controller.
Your method names should correspond to Cashier's
expected convention, specifically, methods should be
prefixed with handle
and the "camel
case" name of the Stripe webhook you wish to
handle. For example, if you wish to handle the
invoice.payment_succeeded
webhook, you
should add a handleInvoicePaymentSucceeded
method to the controller.
<?php
namespace App\Http\Controllers;
use Laravel\Cashier\WebhookController as BaseController;
class WebhookController extends BaseController
{
/**
* Handle a stripe webhook.
*
* @param array $payload
* @return Response
*/
public function handleInvoicePaymentSucceeded($payload)
{
// Handle The Event
}
}
Single Charges
If you would like to make a "one off" charge
against a subscribed customer's credit card, you may use
the charge
method on a billable model
instance. The charge
method accepts the
amount you would like to charge in the lowest
denominator of the currency used by your
application. So, for example, the example
below will charge 100 cents, or $1.00, against the
user's credit card:
$user->charge(100);
The charge
method accepts an array as its
second argument, allowing you to pass any options you
wish to the underlying Stripe charge creation:
$user->charge(100, [
'source' => $token,
'receipt_email' => $user->email,
]);
The charge
method will return
false
if the charge fails. This typically
indicates the charge was denied:
if ( ! $user->charge(100)) {
// The charge was denied...
}
If the charge is successful, the full Stripe response will be returned from the method.
Invoices
You may easily retrieve an array of a billable model's
invoices using the invoices
method:
$invoices = $user->invoices();
When listing the invoices for the customer, you may use the invoice's helper methods to display the relevant invoice information. For example, you may wish to list every invoice in a table, allowing the user to easily download any of them:
<table>
@foreach ($invoices as $invoice)
<tr>
<td>{{ $invoice->dateString() }}</td>
<td>{{ $invoice->dollars() }}</td>
<td><a href="/user/invoice/{{ $invoice->id }}">Download</a></td>
</tr>
@endforeach
</table>
Generating Invoice PDFs
From within a route or controller, use the
downloadInvoice
method to generate a PDF
download of the invoice. This method will automatically
generate the proper HTTP response to send the download
to the browser:
Route::get('user/invoice/{invoice}', function ($invoiceId) {
return Auth::user()->downloadInvoice($invoiceId, [
'vendor' => 'Your Company',
'product' => 'Your Product',
]);
});
