Laravel Stripe Integration: Accept Online Payments Easily

In today’s digital economy, integrating a reliable and efficient payment gateway is essential for any online business. Laravel, one of the most popular PHP frameworks, combined with Stripe, a leading payment processing platform, offers a powerful solution to accept online payments seamlessly. This comprehensive guide will walk you through the process of integrating Stripe into your Laravel application with expert strategies, practical examples, and best practices to ensure a smooth payment experience for your users.

Why Choose Stripe for Payment Processing?

Stripe has become a favorite among developers and businesses due to its robust API, extensive features, and developer-friendly documentation. Here are some compelling reasons to opt for Stripe:

• Easy API Integration: Stripe’s well-documented API allows rapid development and customization.
• Global Reach: Supports multiple currencies and payment methods worldwide.
• Security Compliance: Fully PCI-DSS compliant, ensuring secure handling of payment data.
• Transparent Pricing: No setup fees or monthly charges; pay only per transaction.
• Rich Features: Supports subscriptions, one-time payments, refunds, invoicing, and more.

Preparing Your Laravel Application for Stripe Integration

Before diving into the integration, ensure your Laravel environment is set up correctly:

• Laravel Version: Use Laravel 8.x or later for better compatibility.
• Composer Installed: Ensure Composer is installed to manage dependencies.
• Stripe Account: Create a Stripe account at Stripe.com to obtain API keys.
• HTTPS Enabled: Use HTTPS to secure payment data transmission.

Step-by-Step Laravel Stripe Integration Guide

1. Install Stripe PHP SDK

Use Composer to add Stripe’s official PHP library to your project:

composer require stripe/stripe-php

2. Configure Stripe API Keys

After creating a Stripe account, retrieve your Publishable Key and Secret Key from the dashboard.

Add these keys to your .env file for secure storage:

STRIPE_KEY=pk_test_your_publishable_key
STRIPE_SECRET=sk_test_your_secret_key

Then, add configuration in config/services.php:

'stripe' => [
    'key' => env('STRIPE_KEY'),
    'secret' => env('STRIPE_SECRET'),
],

3. Create Payment Controller

Generate a controller to handle payment logic:

php artisan make:controller PaymentController

Within PaymentController, initialize Stripe and create a method for processing payments:

use StripeStripe;
use StripeCharge;

public function processPayment(Request $request) {
    Stripe::setApiKey(config('services.stripe.secret'));
    
    try {
        $charge = Charge::create([
            'amount' => $request->amount * 100, // amount in cents
            'currency' => 'usd',
            'source' => $request->stripeToken,
            'description' => 'Laravel Stripe Payment',
        ]);
        
        return back()->with('success_message', 'Payment successful!');
    } catch (Exception $e) {
        return back()->withErrors('Error! ' . $e->getMessage());
    }
}

4. Create Payment Form with Stripe Elements

Use Stripe Elements to build a secure, customizable payment form. Include Stripe.js in your Blade template:

<script src="https://js.stripe.com/v3/"></script>

Example payment form:

<form action="{{ route('payment.process') }}" method="POST" id="payment-form">
    @csrf
    <div id="card-element"></div>
    <button type="submit">Pay Now</button>
</form>

<script>
    var stripe = Stripe('{{ config('services.stripe.key') }}');
    var elements = stripe.elements();
    var card = elements.create('card');
    card.mount('#card-element');

    var form = document.getElementById('payment-form');
    form.addEventListener('submit', function(event) {
        event.preventDefault();
        stripe.createToken(card).then(function(result) {
            if (result.error) {
                alert(result.error.message);
            } else {
                var hiddenInput = document.createElement('input');
                hiddenInput.setAttribute('type', 'hidden');
                hiddenInput.setAttribute('name', 'stripeToken');
                hiddenInput.setAttribute('value', result.token.id);
                form.appendChild(hiddenInput);
                form.submit();
            }
        });
    });
</script>

Real-World Example: Subscription Billing with Laravel and Stripe

Beyond one-time payments, Stripe excels in managing subscription billing. Here’s how to implement subscription plans:

• Create subscription products and plans in Stripe Dashboard.
• Use Stripe’s Subscription API to enroll customers.
• Handle webhook events to monitor payment success and failures.

Example snippet for creating a subscription:

use StripeSubscription;

$subscription = Subscription::create([
    'customer' => $customerId,
    'items' => [['plan' => $planId]],
]);

Security Best Practices

• Always use HTTPS to protect payment data.
• Never store raw credit card information on your servers.
• Utilize Stripe Elements to handle sensitive card data securely.
• Implement CSRF protection in your forms.
• Validate and sanitize all inputs server-side.
