+
+ use PayPal\IPN\Event\IPNInvalid;
+ use PayPal\IPN\Event\IPNVerificationFailure;
+ use PayPal\IPN\Event\IPNVerified;
+ use PayPal\IPN\Listener\Http\ArrayListener;
+
+ $listener = new ArrayListener;
+
+ /*
+ * Payload received from PayPal end.
+ */
+ $data = array(
+ 'foo' => 'bar',
+ 'bar' => 'baz',
+ );
+
+ $listener->setData($data);
+
+ $listener = $listener->run();
+
+ $listener->onInvalid(function (IPNInvalid $event) {
+ $ipnMessage = $event->getMessage();
+
+ // IPN message was was invalid, something is not right! Do your logging here...
+ });
+
+ $listener->onVerified(function (IPNVerified $event) {
+ $ipnMessage = $event->getMessage();
+
+ // IPN message was verified, everything is ok! Do your processing logic here...
+ });
+
+ $listener->onVerificationFailure(function (IPNVerificationFailure $event) {
+ $error = $event->getError();
+
+ // Something bad happend when trying to communicate with PayPal! Do your logging here...
+ });
+
+ $listener->listen();
+```
+
+### Using InputStreamListener
+
+```php
+ use PayPal\IPN\Event\IPNInvalid;
+ use PayPal\IPN\Event\IPNVerificationFailure;
+ use PayPal\IPN\Event\IPNVerified;
+ use PayPal\IPN\Listener\Http\InputStreamListener;
+
+ $listener = new InputStreamListener;
+
+ $listener = $listener->run();
+
+ $listener->onInvalid(function (IPNInvalid $event) {
+ $ipnMessage = $event->getMessage();
+
+ // IPN message was was invalid, something is not right! Do your logging here...
+ });
+
+ $listener->onVerified(function (IPNVerified $event) {
+ $ipnMessage = $event->getMessage();
+
+ // IPN message was verified, everything is ok! Do your processing logic here...
+ });
+
+ $listener->onVerificationFailure(function (IPNVerificationFailure $event) {
+ $error = $event->getError();
+
+ // Something bad happend when trying to communicate with PayPal! Do your logging here...
+ });
+
+ $listener->listen();
+```
