To integrate the official Stripe Payment Gateway in your Laravel application, you just have to follow these easy steps:

Installation

Starting by making a Laravel installation , and if you've already settled it then you can follow the next steps.
composer create-project laravel/laravel stripe-checkout

checkout.blade.php

In this step , you just have to set a button in your blade template in order redirect to stripe checkout page .
In this I will use this example :

<button id="checkout-button" type="button">Proceed to Checkout</button>

Installing Stripe-Php library via Composer

Following it with installing the stripe-php library via composer :
composer require stripe/stripe-php

Creating the Checkout Session

In the checkout blade template that we had settled ,it is required to create the checkout session in it :

<?php
require 'vendor/autoload.php';
// This is your test secret API key.
\Stripe\Stripe::setApiKey('sk_test_51JX1BnCwSqIoxRpKte18TcaGSEegx1UX1NKYaKGDCwFkbyDWeYiQW4cKxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx');
$session = \Stripe\Checkout\Session::create([
    'line_items' => [[
      'price_data' => [
        'currency' => 'usd',
        'product_data' => [
          'name' => 'T-shirt',
        ],
        'unit_amount' => 2000,
      ],
      'quantity' => 1,
    ]],
    'mode' => 'payment',
    'success_url' => 'https://example.com/success',
    'cancel_url' => 'https://example.com/cancel',
  ]);
?>
<script src="https://js.stripe.com/v3/"></script>
<script>
const stripe = Stripe('pk_test....') //Your Publishable key.
const btn = document.getElementById('checkout-button');
btn.addEventListener("click", function() 
{
stripe.redirectToCheckout({
$sessionId: "<?php echo $session->id ?> "
})
}
</script>

Now run your application.
In case you had the require(vendor/autoload.php) error :
Instead of <?php require 'vendor/autoload.php';
Add this
<?php require_once __DIR__. '/../../../vendor/autoload.php';
Now run your application !

Connecting MySQL Database and Stripe Checkout details

• In your VerifyCsrfToken.php add this following line: protected $except = [ 'webhook'] ;
• Now install expose via composer:(https://expose.dev/docs/getting-started/installation) composer global require beyondcode/expose
• Activate your tokken :

expose tokken xxxxxxxxxxx //Create an account in expose.dev and you will get the tokken

• expose share http://localhost
• You will get a global link for your laravel application only temporary. The reason for this, is to link webhook events to an existing website. Copy your laravel application exposed link *Visit stripe dashboard(make sure you are in the **Test Mode),Then clicking on Webhooks, in the **Endpoint URL* add your website link followed by /webhook.Then select your events(charge.succeeded to see if the payment was successful)
• In your web.php:

Route::post('webhook/payment/succeeded', [App\Http\Controllers\StripePaymentController::class, 'stripePost']) ;

• In StripePaymentController.php

<?php
namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Payment;
use App\Models\Product;
use Illuminate\Support\Facades\DB;
use Stripe;

class StripePaymentController extends Controller
{
    public function stripePost(Request $request)
    {
        if($request->type === "charge.succeeded"){
            try{

    Payment::create([
       'stripe_id' => $request->data['object']['id'],
        'amount' => $request->data['object']['amount'],
        'email' => $request->data['object']['billing_details']['email'],
        'name' => $request->data['object']['billing_details']['name']
    ]);
   } catch (\Exception $e) {
               return $e->getMessage();
           }

        }
    }
}

• In Payment.php Model: protected $guarded = [] ;
• In create-payments.php migration :

    public function up()
    {
        Schema::create('payments', function (Blueprint $table) {
            $table->id();
            $table->string('stripe_id'); // stripe payment id
            $table->integer('amount');
            $table->string('email');
            $table->string('name');
            $table->timestamps();
        });
    }

• Then Migrate the payments table .Then try the checkout and see the details after a successful checkout.
