<p>This plugins gives you a great framework to use for integrating with PayPal.<br />
It stores both live and sandbox API credentials and allows you to switch back<br />
and forth easily.  All NVP API calls are passed through the framework and<br />
default values such as API version, API credentials, and even currency code are<br />
added to the request based on settings from the admin panel.</p>
<p>It also has a built in IPN listener that validates messages as coming from<br />
PayPal then throws WordPress actions based on messages received.  For example it<br />
throws “paypal-recurring_payment_profile_cancel” when someone cancels a<br />
recurring payment that they had set up with you.  It passes along all the info<br />
that PayPal sent to the action, so it’s simple to create other plugins that use<br />
this one.</p>
<p>Requires PHP5.</p>
