Stripe: как я могу получить данные для хранения на моей платформе

Я интегрирую Stripe для своей платформы, которая использует Next.js и Laravel.

Я не могу понять, как я могу получить данные и сохранить их в базе данных MY Platform. Например, пользователь покупает клавиатуру за 50 долларов. Как я могу получить эту информацию item_name и price в Laravel.

Ниже мой код. Спасибо.

next.js : страница предметов

<form action = "/api/checkout_sessions/buy" method = "POST">
    <button type = "submit">
        Pay $50
    </button>
</form>

Итак, если пользователь нажмет кнопку «Заплатить 50 долларов», он будет перенаправлен на страницу оформления заказа, размещенную на stript. А ниже pages/api/checkout_sessions/buy.js.

const stripe = require('stripe')(process.env.STRIPE_SECRET_KEY);

export default async function handler(req, res) {
  if (req.method === 'POST') {
    try {
      // Create Checkout Sessions from body params.
      const session = await stripe.checkout.sessions.create({
        payment_method_types: ["card"],
        line_items: [
          {
              // Provide the exact Price ID (for example, pr_1234) of the product you want to sell
              price: 'price_random',
              quantity: 1,
            },
          ],
        mode: 'payment',
        success_url: `${req.headers.origin}/?success=true`,
        cancel_url: `${req.headers.origin}/?canceled=true`,
      });

      res.redirect(303, session.url);
    } catch (err) {
      res.status(err.statusCode || 500).json(err.message);
    }
  } else {
    res.setHeader('Allow', 'POST');
    res.status(405).end('Method Not Allowed');
  }
}

До сих пор я просто следую этим инструкциям: https://stripe.com/docs/checkout/quickstart.

После заполнения необходимой информации на странице оформления заказа, размещенной на Stript, чтобы проверить, прошел платеж успешно или нет, я написал веб-хуки в своем бэкэнде и протестировал его с помощью stripe cli. А это ниже. Опять же, я просто следую этим инструкциям. https://stripe.com/docs/payments/checkout/fulfill-orders

api.php

Route::post('webhook', function() {

    // Set your secret key. Remember to switch to your live secret key in production.
    // See your keys here: https://dashboard.stripe.com/apikeys
    \Stripe\Stripe::setApiKey('sk_test_');

    function print_log($val) {
        return file_put_contents('php://stderr', print_r($val, TRUE));
    }

    // You can find your endpoint's secret in your webhook settings
    $endpoint_secret = 'whsec_';

    $payload = @file_get_contents('php://input');
    $sig_header = $_SERVER['HTTP_STRIPE_SIGNATURE'];
    $event = null;

    try {
        $event = \Stripe\Webhook::constructEvent($payload, $sig_header, $endpoint_secret);
    } 
    catch(\UnexpectedValueException $e) {
        // Invalid payload
        http_response_code(400);
        exit();
    } catch(\Stripe\Exception\SignatureVerificationException $e) {
        // Invalid signature
        http_response_code(400);
        exit();
    }

    function fulfill_order($session) {
        // TODO: fill me in
        print_log("Fulfilling order...");
        print_log($session);
    }

    // Handle the checkout.session.completed event
    if ($event->type == 'checkout.session.completed') {
        $session = $event->data->object;

        Log::info('session----');
        Log::info($session);

        Log::info('payload----');
        Log::info($payload);

        Log::info('event----');
        Log::info($event);

        // Fulfill the purchase...
        fulfill_order($session);
    }

    if ($event->type == 'payment_intent.succeeded') {
        Log::info('payment successful');
    }

    http_response_code(200);
});

Выполняя приведенную ниже команду в Strip cli,

stripe listen --forward-to localhost:3000/api/webhook (which will execute the above function when I clicked pay in stripe-hosted checkout page)

Я получил следующий результат в консоли stript-cli.

payment_intent.created [evt_random]

Я получил следующий результат в консоли laravel.

Вопрос:

Платеж прошел успешно! Но как я могу сохранить эти keyboard и 50 в моей базе данных и где написать этот код, чтобы я знал, что пользователь купил этот товар по этой цене.
