Stripe payment gateway integration in laravel step by step guide

on

Stripe is a popular payment gateway that allows you to accept payments online. Integrating Stripe in Laravel application is a straightforward process, and this step-by-step guide will walk you through the entire process.

Prerequisites

Before you start integrating Stripe with your Laravel application, you need to ensure that you have the following prerequisites:

  • A working Laravel installation.
  • A Stripe account.
  • Composer installed on your local machine.

Step 1: Install Stripe Package

To begin, you need to install the Stripe PHP library in your Laravel application. You can install it using Composer by running the following command in your terminal:

composer require stripe/stripe-php

Step 2: Set Up Stripe API Keys

To use Stripe, you need to set up your API keys. You can find your API keys in the Stripe Dashboard. Navigate to the Developers > API Keys section, where you will find your Publishable Key and Secret Key.

Next, create a new .env file in the root directory of your Laravel application and add the following lines to it:

STRIPE_KEY=your_publishable_keySTRIPE_SECRET=your_secret_key

Make sure to replace your_publishable_key and your_secret_key with your actual Stripe API keys.

Step 3: Create a Payment Form

To create a payment form, you need to create a new route and controller method in your Laravel application. For example, let’s create a route at /checkout and a checkout method in our PaymentController.

// routes/web.phpRoute::get('/checkout', [PaymentController::class, 'checkout'])->name('checkout');
// app/Http/Controllers/PaymentController.phpuse Illuminate\Http\Request;class PaymentController extends Controller{    public function checkout(Request $request)    {        return view('checkout');    }}

Next, create a new Blade view at resources/views/checkout.blade.php and add the following HTML code to it:

<form action="{{ route('checkout') }}" method="POST">    @csrf    <input type="text" name="name" placeholder="Name">    <input type="email" name="email" placeholder="Email">    <input type="number" name="amount" placeholder="Amount">    <button type="submit">Pay Now</button></form>

This form will collect the user’s name, email, and payment amount.

Step 4: Process the Payment

To process the payment, you need to handle the form submission in your checkout method. First, you need to validate the form data using Laravel’s built-in validation rules. Then, you can create a new charge using the Stripe PHP library.

	// app/Http/Controllers/PaymentController.phpuse Illuminate\Http\Request;use Stripe\Charge;use Stripe\Customer;use Stripe\Stripe;class PaymentController extends Controller{    public function checkout(Request $request)    {        // Validate the form data        $request->validate([            'name' => 'required|string',            'email' => 'required|email',            'amount' => 'required|numeric|min:1',        ]);        // Set your secret key        Stripe::setApiKey(config('services.stripe.secret'));        // Create a new customer        $customer = Customer::create([            'email' => $request->email,            'name' => $request->name,        ]);        // Charge the customer        $charge = Charge::create([            'customer' => $customer->id,            'amount' => $request->amount * 100,			'currency' => 'usd',			'description' => 'Payment for ' . $request->name,    ]);    // Return a success message    return 'Payment processed successfully!';}

In the code above, we first validate the form data using Laravel’s built-in validation rules. Then, we set our Stripe secret key and create a new customer object using the customer’s email and name. Finally, we create a new charge object using the customer’s ID, the payment amount (in cents), the currency, and a description.

Once the charge has been processed, we return a success message.

Step 5: Test the Payment

Now that you have integrated Stripe with your Laravel application, it’s time to test the payment. Start your Laravel server by running the following command in your terminal:

php artisan serve

Then, navigate to http://localhost:8000/checkout in your web browser. Fill in the form with test data and submit it. If everything was set up correctly, you should see a success message.

Conclusion

In this tutorial, you learned how to integrate Stripe with your Laravel application. You learned how to install the Stripe PHP library, set up your API keys, create a payment form, process the payment, and test the payment. With this knowledge, you can now easily accept payments online using Stripe and Laravel.
