 * Created by Raza Mehdi .
 */
return [
    'mode'    => env('PAYPAL_MODE', 'sandbox')
    'sandbox' => [
        'username'    => env('PAYPAL_SANDBOX_API_USERNAME', ''),
        'password'    => env('PAYPAL_SANDBOX_API_PASSWORD', ''),
        'secret'      => env('PAYPAL_SANDBOX_API_SECRET', ''),
        'certificate' => env('PAYPAL_SANDBOX_API_CERTIFICATE', ''),
        'app_id'      => 'APP-80W284485P519543T',
    ],
    'live' => [
        'username'    => env('PAYPAL_LIVE_API_USERNAME', ''),
        'password'    => env('PAYPAL_LIVE_API_PASSWORD', ''),
        'secret'      => env('PAYPAL_LIVE_API_SECRET', ''),
        'certificate' => env('PAYPAL_LIVE_API_CERTIFICATE', ''),
        'app_id'      => '',
    ],
    'payment_action' => 'Sale',
    'currency'       => env('PAYPAL_CURRENCY', 'USD'),
    'billing_type'   => 'MerchantInitiatedBilling',
    'notify_url'     => '',
    'locale'         => '',
    'validate_ssl'   => false,
];

Step 3: Create Routes

Here, we need to add resource route for paypal payment gateway. so open your “routes/web.php” file and add following route.

routes/web.php

Route::get('payment', 'PayPalController@payment')->name('payment');
Route::get('cancel', 'PayPalController@cancel')->name('payment.cancel');
Route::get('payment/success', 'PayPalController@success')->name('payment.success');

Step 4: Create PayPalController Controller

In this step, now we should create new controller as PayPalController. So run bellow command and create new controller. bellow controller for create with some methods.

php artisan make:controller PayPalController

After bellow command you will find new file in this path “app/Http/Controllers/PayPalController.php”.

app/Http/Controllers/PayPalController.php

<?php
namespace AppHttpControllers;
use IlluminateHttpRequest;
use SrmklivePayPalServicesExpressCheckout;
class PayPalController extends Controller
{
    /**
     * Responds with a welcome message with instructions
     *
     * @return IlluminateHttpResponse
     */
    public function payment()
    {
        $data = [];
        $data['items'] = [
            [
                'name' => 'ItSolutionStuff.com',
                'price' => 100,
                'desc'  => 'Description for ItSolutionStuff.com',
                'qty' => 1
            ]
        ];
        $data['invoice_id'] = 1;
        $data['invoice_description'] = "Order #{$data['invoice_id']} Invoice";
        $data['return_url'] = route('payment.success');
        $data['cancel_url'] = route('payment.cancel');
        $data['total'] = 100;
        $provider = new ExpressCheckout;
        $response = $provider->setExpressCheckout($data);
        $response = $provider->setExpressCheckout($data, true);
        return redirect($response['paypal_link']);
    }
    /**
     * Responds with a welcome message with instructions
     *
     * @return IlluminateHttpResponse
     */
    public function cancel()
    {
        dd('Your payment is canceled. You can create cancel page here.');
    }
    /**
     * Responds with a welcome message with instructions
     *
     * @return IlluminateHttpResponse
     */
    public function success(Request $request)
    {
        $response = $provider->getExpressCheckoutDetails($request->token);
        if (in_array(strtoupper($response['ACK']), ['SUCCESS', 'SUCCESSWITHWARNING'])) {
            dd('Your payment was successfully. You can create success page here.');
        }
        dd('Something is wrong.');
    }
}

Step 5: Create Blade File

In this step, we need to update welcome.blade.php file. in this file we will put one button for paypal payment gateway. so let’s put bellow code:

resources/views/products/welcome.blade.php

<!doctype html>
<html>
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">

        <!-- Styles -->
        <style>
            html, body {
                background-color: #fff;
                color: #636b6f;
                font-family: 'Nunito', sans-serif;
                font-weight: 200;
                height: 100vh;
                margin: 0;
            }
            .content {
                margin-top: 100px;
                text-align: center;
            }
        </style>
    </head>
    <body>
        <div >
            <div >
                <h1>Laravel 5.8 PayPal Integration Tutorial - ItSolutionStuff.com</h1>
                <table border="0" cellpadding="10" cellspacing="0" align="center"><tr><td align="center"></td></tr><tr><td align="center"><a href="https://www.paypal.com/in/webapps/mpp/paypal-popup" title="How PayPal Works" onclick="javascript:window.open('https://www.paypal.com/in/webapps/mpp/paypal-popup','WIPaypal','toolbar=no, location=no, directories=no, status=no, menubar=no, scrollbars=yes, resizable=yes, width=1060, height=700'); return false;"><img src="https://www.paypalobjects.com/webstatic/mktg/Logo/pp-logo-200px.png" border="0" alt="PayPal Logo"></a></td></tr></table>
                <a href="{{ route('payment') }}" >Pay $100 from Paypal</a>
            </div>
        </div>
    </body>
</html>

Step 6: Configuration

.env

PAYPAL_SANDBOX_API_USERNAME=sb-e2n47..
PAYPAL_SANDBOX_API_PASSWORD=XKCGW...
