Laravel Development: How to handle subscription payments using Laravel Cashier and Braintree?

In today’s subscription economy, many businesses and startups offer a variety of subscription services, from music, movies, games to cloud storage and applications, and more. If you are a developer, you need to build a system that can handle subscription payments. In this article, we will explain how to achieve this using Laravel Cashier and Braintree.

Laravel Cashier is a Laravel extension that provides a simple yet powerful interface to handle subscriptions and payments. Braintree is a global online payment processing platform that makes it easy to accept various payment methods.

We will use Laravel 8 and Braintree for specific implementation. You need to install Laravel Cashier and Braintree extensions in your project. The following are the specific implementation steps:

1. Set environment variables

First, you need to set environment variables in the project to store the Braintree API key and other settings. You can set environment variables in .env files. Here is an example of using a Braintree API test key:

BRAINTREE_ENV=sandbox
BRAINTREE_MERCHANT_ID=your_merchant_id
BRAINTREE_PUBLIC_KEY=your_public_key
BRAINTREE_PRIVATE_KEY=your_private_key

2. Creating a Braintree Payment Portal

Next, you need to create a payment portal in the Braintree control panel. Each portal has a unique identifier and credentials that will be used to process payments. After creating a portal in the control panel, copy and save your credentials.

3. Configuring Braintree

Then, you need to add a Braintree configuration in the config/services.php file. Here is an example configuration:

'braintree' => [
    'environment' => env('BRAINTREE_ENV'),
    'merchant_id' => env('BRAINTREE_MERCHANT_ID'),
    'public_key' => env('BRAINTREE_PUBLIC_KEY'),
    'private_key' => env('BRAINTREE_PRIVATE_KEY'),
],

4. Creating a Subscription Plan

Now you can create a subscription plan using Laravel Cashier and Braintree. A subscription plan is a service that is charged a recurring fee, such as monthly or annually. Here is an example of how to create a subscription plan:

use LaravelCashierSubscription;

$subscription = Subscription::create([
    'name' => 'Monthly Subscription Plan',
    'stripe_id' => 'monthly-subscription-plan',
    'stripe_plan' => 'monthly',
    'quantity' => 1,
    'trial_period_days' => 14,
]);

$user->subscriptions()->save($subscription);

In this example, we create a subscription plan called "Monthly Subscription Plan", its stripe_id is "monthly-subscription-plan", stripe_plan is "monthly". The 'quantity' parameter specifies the quantity of the subscription, and the 'trial_period_days' parameter specifies the number of days of the trial period. After saving the subscription information, the user will be able to subscribe to the plan.

5. Processing Payments

Finally, you need to process your subscription payments. Luckily, Laravel Cashier already handles the payment details for us. With Laravel Cashier, you can easily process payments without worrying about the complexities of payment gateways. Here is an example of handling a payment:

use LaravelCashierCashier;

$user = User::find(1);

$paymentMethod = $user->defaultPaymentMethod();

$payment = $user->charge(10, $paymentMethod);

if ($user->subscribed('monthly-subscription-plan')) {
    // 更新用户的订阅和付款信息
    $user->subscription('monthly-subscription-plan')->update([
        'stripe_id' => $payment->id,
        'ends_at' => null,
    ]);
}

In this example, we use the $user->defaultPaymentMethod() method to get the user's default payment method and charge them $10. If the subscription plan is "monthly-subscription-plan", we will update the user's subscription and payment information.

Conclusion

Processing subscription payments has become easier with Laravel Cashier and Braintree. You can easily create and manage subscription plans, and process payments. Of course, this is just a simple example and you can add more functionality to your own projects. Hope this article helps you!
