Get Started

In this chapter we are going to talk about the most common task: purchase of a product using Paypal ExpressCheckout. We assume you already read basic get it started. Here we just show you modifications you have to put to the files shown there.


The preferred way to install the library is using composer. Run composer require to add dependencies to composer.json:

php composer.phar require payum/paypal-express-checkout-nvp php-http/guzzle7-adapter



use Payum\Core\PayumBuilder;
use Payum\Core\Payum;

/** @var Payum $payum */
$payum = (new PayumBuilder())
    ->addGateway('gatewayName', [
        'factory' => 'paypal_express_checkout',
        'username'  => 'change it',
        'password'  => 'change it',
        'signature' => 'change it',
        'sandbox'   => true,



Here you have to modify the gatewayName value. Set it to paypal_express_checkout. The rest remain the same as described in basic get it started documentation.
