namespace App\Http\Controllers;
use Illuminate\Http\Request;

use Srmklive\PayPal\Services\ExpressCheckout;
class PayPalController extends Controller

{

/**

* Responds with a welcome message with instructions

*

* @return \Illuminate\Http\Response

*/

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 = $provider-&gt;setExpressCheckout($data);

    $response = $provider-&gt;setExpressCheckout($data, true);

    return redirect($response['paypal_link']);
}

/**
 * Responds with a welcome message with instructions
 *
 * @return \Illuminate\Http\Response
 */
public function cancel()
{
    dd('Your payment is canceled. You can create cancel page here.');
}

/**
 * Responds with a welcome message with instructions
 *
 * @return \Illuminate\Http\Response
 */
public function success(Request $request)
{
    $response = $provider-&gt;getExpressCheckoutDetails($request-&gt;token);

    if (in_array(strtoupper($response['ACK']), ['SUCCESS', 'SUCCESSWITHWARNING'])) {
        dd('Your payment was successfully. You can create success page here.');
    }

    dd('Something is wrong.');
