+If you want to use the Laravel config file: The first step is to publish the config with `artisan vendor:publish`. This will create the config file `storage/paypal_payment.php` (`app/config/paypal_payment.php` in Laravel 4). Configurate it, then replace the `setConfig()` method call (see above) with:
+
+```
+$config = config('paypal_payment'); // Get all config items as multi dimensional array
+$flatConfig = array_dot($config); // Flatten the array with dots
+
+$this->_apiContext->setConfig($flatConfig);
+```
