What is Laravel Cashier?

Let's dive deeper into Laravel Cashier. At its core, Cashier is a Laravel package designed to streamline subscription billing integration. It acts as a bridge between your Laravel application and popular payment gateways like Stripe and Paddle, abstracting away much of the complexity involved in managing subscriptions, handling payments, and dealing with invoices. Instead of wrestling with raw API calls and intricate database schemas, Cashier provides an expressive, fluent API that allows you to focus on building your core application features.

Without Cashier, you'd need to manually handle user subscriptions, track payment statuses, generate invoices, and manage potential issues like failed payments or subscription cancellations. This involves writing a significant amount of code, dealing with security considerations, and ensuring compliance with payment processing standards. Cashier simplifies this entire process by providing pre-built functionality for common billing tasks.

With Cashier, you can easily define subscription plans, allow users to subscribe to these plans, process payments securely, and manage subscription lifecycles. It handles things like proration, trial periods, coupons, and even taxes with minimal effort on your part. It integrates seamlessly with Laravel's existing features, such as Eloquent models and database migrations, making it a natural fit for any Laravel project. In essence, Cashier empowers you to implement sophisticated billing logic without getting bogged down in the technical details. It's like having a dedicated billing expert built right into your application.

Setting Up Laravel Cashier

Okay, so you're sold on Laravel Cashier. Awesome! Let's get down to the nitty-gritty of setting it up. Don't worry, it's not as scary as it sounds. We'll walk through it step by step:

1. Install the Package: First things first, you need to install the Cashier package using Composer. Open up your terminal and run this command:

   composer require laravel/cashier
   

   This command tells Composer to download and install the Cashier package and its dependencies into your Laravel project. It's like ordering the necessary building blocks for your billing system.
2. Configure Your Database: Next up, you need to run Cashier's migrations to add the necessary columns to your users table and create the subscriptions table. Fire up your terminal again and run:

   php artisan migrate
   

   These migrations add columns like stripe_id, pm_type, and pm_last_four to your users table, which Cashier uses to store customer information. They also create the subscriptions table, which keeps track of user subscriptions and their statuses. Think of it as laying the foundation for your billing database.
3. Set Your API Keys: Now, you need to tell Cashier about your Stripe or Paddle API keys. Open up your .env file and add your Stripe or Paddle secret key and publishable key:

   STRIPE_SECRET=your_stripe_secret
   STRIPE_KEY=your_stripe_key
   

   Replace your_stripe_secret and your_stripe_key with your actual Stripe API keys. These keys are like the keys to the kingdom, allowing Cashier to communicate with Stripe on your behalf. Make sure you keep them safe and secure.
4. Add the Billable Trait: To make your User model billable, you need to add the Billable trait to it. Open up your App\Models\User model and add use Laravel\Cashier\Billable; to the top of the file, and then use Billable; inside the class definition:

   <?php
   
   namespace App\Models;
   
   use Illuminate\Foundation\Auth\User as Authenticatable;
   use Illuminate\Notifications\Notifiable;
   use Laravel\Cashier\Billable; // Add this line
   
   class User extends Authenticatable
   {
       use Notifiable, Billable; // Add Billable here
   
       // ...
   }
   

   The Billable trait adds a bunch of helpful methods to your User model, allowing you to easily manage subscriptions, retrieve invoices, and perform other billing-related tasks. It's like giving your User model a billing superpower.
5. (Optional) Configure Cashier: Cashier has a bunch of configuration options that you can customize to fit your needs. You can publish the Cashier configuration file using:

   php artisan vendor:publish --tag=
