Set Paypal credentials into config/paypal.php

    'sandbox' => [
        'client_id'         => env('PAYPAL_SANDBOX_CLIENT_ID', ''),
        'client_secret'     => env('PAYPAL_SANDBOX_CLIENT_SECRET', ''),
        'app_id'            => '',
    ],
    ......
    ......
];

Create Routes

routes/web.php

 Route::get('paypal-onboard', [PaypalController::class, 'onBoard'])->name('paypal.init');
 Route::get('paypal-payment-success', [PaypalController::class, 'success'])->name('paypal.success');
 Route::get('paypal-payment-failed', [PaypalController::class, 'failed'])->name('paypal.failed');

Create Controller

app\Http\Controllers\PaypalController.php

setCurrency('EUR');
        $provider->getAccessToken();
        $data = [
            "intent"              => "CAPTURE",
            "purchase_units"      => [
                [
                    "amount" => [
                        "value"         => 100,
                        "currency_code" => getCurrencyCode(),
                    ],
                ],
            ],
            "application_context" => [
                "cancel_url" => route('user.paypal.failed'),
                "return_url" => route('user.paypal.success'),
            ],
        ];

        $order = $provider->createOrder($data);

        return redirect($order['links'][1]['href']);
    }

    public function failed()
    {
        dd('Your payment has been declend. The payment cancelation page goes here!');
    }

    public function success(Request $request)
    {
        $provider = new PayPal();      // To use express checkout.
        $provider->getAccessToken();
        $token = $request->get('token');

        $orderInfo = $provider->showOrderDetails($token);
        $response = $provider->capturePaymentOrder($token);

        dump($orderInfo);
        dd($response);
    }
}

That's it. Enjoy.
