composer require paypal/rest-api-sdk-php

PAYPAL_CLIENT_ID=your_paypal_client_id
PAYPAL_SECRET=your_paypal_secret
PAYPAL_MODE=sandbox

php artisan make:provider PayPalServiceProvider

<?php

namespace App\Providers;

            $mode = config('paypal.mode');

            $apiContext = new ApiContext(
                new OAuthTokenCredential($clientId, $clientSecret)
            );

            $apiContext->setConfig([

            ]);

}

'providers' => [
