When it comes to integrating payment gateways in a Laravel application, the process can seem daunting—but it doesn't have to be. In this detailed guide, we'll walk you through the necessary steps to seamlessly incorporate Stripe and PayPal into your Laravel app. By the end of this article, you'll have a clear understanding and the confidence to handle payment integrations effectively.
Before diving into payment gateway integration, it’s crucial to have your Laravel application properly set up. Laravel, a robust PHP framework, is renowned for its simplicity and elegance. To get started, make sure you have Laravel installed and configured on your server.

Start by installing Laravel via Composer. In your terminal, run the following command:
composer create-project --prefer-dist laravel/laravel paymentGatewayApp
This command will create a new Laravel project named paymentGatewayApp.

Navigate to your project folder and update the .env file with your database credentials. This ensures Laravel can interact with your database:
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=your_database_name
DB_USERNAME=your_database_user
DB_PASSWORD=your_database_password
Run the migration command to set up your database:
php artisan migrate
Integrating Stripe into your Laravel application enables you to accept credit card payments effortlessly. Stripe's API is user-friendly and highly secure, making it a popular choice among developers.
Laravel Cashier provides an expressive interface for managing Stripe payments in Laravel. Install Laravel Cashier using Composer:
composer require laravel/cashier
Next, add your Stripe API keys to your .env file. You can obtain these keys from your Stripe dashboard:
STRIPE_KEY=your_stripe_key
STRIPE_SECRET=your_stripe_secret
In your Blade view, create a payment form to collect the user's payment details. Here’s an example form:
<form action="/charge" method="post" id="payment-form">
@csrf
<div class="form-group">
<label for="card-element">Credit or debit card</label>
<div id="card-element"></div>
<div id="card-errors" role="alert"></div>
</div>
<button type="submit" class="btn btn-primary">Submit Payment</button>
</form>
In your routes file (web.php), define a route to handle the form submission:
use IlluminateHttpRequest;
use StripeStripe;
use StripeCharge;
Route::post('/charge', function (Request $request) {
Stripe::setApiKey(env('STRIPE_SECRET'));
$charge = Charge::create([
'amount' => 999, // Amount in cents
'currency' => 'usd',
'source' => $request->stripeToken,
'description' => 'Test Payment',
]);
return 'Payment Successful!';
});
Finally, test your Stripe integration by running your Laravel application and submitting a test payment. Ensure all parts of the payment process work seamlessly.
PayPal remains one of the most widely used payment gateways globally. It offers a secure and straightforward method for handling payments, making it an essential addition to your Laravel application.
Begin by installing the PayPal SDK for PHP via Composer:
composer require paypal/rest-api-sdk-php
Add your PayPal credentials to the .env file. You can retrieve these credentials from your PayPal developer account:
PAYPAL_CLIENT_ID=your_paypal_client_id
PAYPAL_SECRET=your_paypal_secret
Create a new controller to handle PayPal payments. Use the following command to generate a controller:
php artisan make:controller PayPalController
In your PayPalController.php, add the following code to manage the PayPal payment process:
use PayPalApiAmount;
use PayPalApiPayer;
use PayPalApiPayment;
use PayPalApiRedirectUrls;
use PayPalApiTransaction;
public function createPayment(Request $request)
{
$payer = new Payer();
$payer->setPaymentMethod('paypal');
$amount = new Amount();
$amount->setTotal('10.00');
$amount->setCurrency('USD');
$transaction = new Transaction();
$transaction->setAmount($amount);
$transaction->setDescription('Test Payment');
$redirectUrls = new RedirectUrls();
$redirectUrls->setReturnUrl(url('/paypal/success'))
->setCancelUrl(url('/paypal/cancel'));
$payment = new Payment();
$payment->setIntent('sale')
->setPayer($payer)
->setTransactions([$transaction])
->setRedirectUrls($redirectUrls);
try {
$payment->create($this->apiContext);
return redirect()->away($payment->getApprovalLink());
} catch (Exception $ex) {
return redirect()->route('home')->with('error', 'Error processing PayPal payment');
}
}
In your web.php file, define routes for initiating the payment and handling the payment response:
Route::get('/paypal', 'PayPalController@createPayment');
Route::get('/paypal/success', 'PayPalController@handleSuccess');
Route::get('/paypal/cancel', 'PayPalController@handleCancel');
In PayPalController.php, add methods to process the payment outcome:
public function handleSuccess(Request $request)
{
// Handle successful payment here
return 'Payment Successful!';
}
public function handleCancel()
{
// Handle canceled payment here
return 'Payment Canceled';
}
Security is a top priority when dealing with payment gateways. Always follow best practices to safeguard your users' sensitive information.
Ensure your application is served over HTTPS to encrypt data between the customer and your server.
Sanitize and validate all input data to prevent security breaches. Use Laravel's validation features to enforce strict data validation rules.
Regularly monitor transactions for any suspicious activity. Implement logging mechanisms to track payment requests and responses.
