Stripe Payment Gateway Integration in CakePHP 4

Reading Time: 8 minutes

As we all know in most web application either in CakePHP 4 or any of the PHP Framework, we sometimes need to integrate payment gateway. Inside this article, we will see Stripe payment Integration in CakePHP 4. Stripe payment system settings in CakePHP 4. Easy and in complete detailed concept.

Let’s get started.

CakePHP 4 Installation

To create a CakePHP project, run this command into your shell or terminal. Make sure composer should be installed in your system.

$ composer create-project --prefer-dist cakephp/app:~4.0 mycakephp

Above command will creates a project with the name called mycakephp.

Stripe PHP Package Installation

We will install stripe package via composer into CakePHP 4 setup. Open CakePHP 4 project in terminal and hit this composer command.

$ composer require stripe/stripe-php

Set Stripe API Key and SECRET

Open up /config/paths.php file of CakePHP 4 application. Into the file, set few constants stripe api key, secret & vendor folder.

defined("VENDOR_PATH") || define('VENDOR_PATH', ROOT . DS . 'vendor');
defined("STRIPE_KEY") || define('STRIPE_KEY', "pk_test_MaQhP2b8XqG9R7PTL6VUmipt");
defined("STRIPE_SECRET") || define('STRIPE_SECRET', "sk_test_MtVxg0tJfCGJXQY8xZlu69Ie");

This is our stripe sandbox detail, you can replace it with your own. If you are wondering to find stripe test account keys. Follow these steps –

  • You need to enable Viewing test data to use Test account details
  • Go to Developer >> Click on API keys

Create Routes

Next, we need to set CakePHP 4 stripe payment gateway application routes. To configure routes, open up /config/routes.php file.

$routes->scope('/', function (RouteBuilder $builder) {
  //... other routes
  $builder->connect('/stripe', ['controller' => 'Stripes', 'action' => 'stripe']);
  $builder->connect('/payment', ['controller' => 'Stripes', 'action' => 'payment']);

Create Controller File

Create application controller in setup. To create controller file, go to /src/Controller/StripesController.php and create this file. Open StripesController.php and paste the given code.


namespace App\Controller;
use Stripe;

class StripesController extends AppController
    public function stripe()
        $this->set("title", "Stripe Payment Gateway Integration");

    public function payment()
        require_once VENDOR_PATH. '/stripe/stripe-php/init.php';

        $stripe = Stripe\Charge::create ([
                "amount" => 70 * 100,
                "currency" => "usd",
                "source" => $_REQUEST["stripeToken"],
                "description" => "Test payment via Stripe From" 
        // after successfull payment, you can store payment related information into your database
        $this->Flash->success(__('Payment done successfully'));
        return $this->redirect(['action' => 'stripe']);

Create Template File

Let’s create template file for setting the layout of payment details for user. Firstly we need to create a folder in /templates with the name as Stripes. Create a file stripe.php inside /templates/Stripes/stripe.php. Open file and paste the given code

            $form.append("<input type='hidden' name='stripeToken' value='" + token + "'/>");

Application Testing

Now, here you can test with these given test card details.

Open project in terminal and start development server

$ bin/cake server -p 8765

This is the Form when you open the route http://localhost:8765/stripe

Name: Sample
Number: 4242 4242 4242 4242
