/**
 * @package CRM
 * @copyright CiviCRM LLC https://civicrm.org/licensing
 * This script processes "Instant Payment Notifications" (IPNs).  Modern
 * Payment Processors use the /civicrm/payment/ipn/123 endpoint instead (where
 * 123 is the payment processor ID), however a quirk in the way PayPal works
 * means that we need to maintain this script.
 *
 * Note on PayPal.
 *
 * Using PayPal Website Standard (which uses the old PayPal button API) the IPN
 * endpoint is passed to PayPal with every transaction, and it is then stored
 * by PayPal who unhelpfully do not give you any way to retrieve or change
 * this.
 *
 * This means that if you provide URL1 when setting up a recurring
 * contribution, then you will always need to maintain URL1 because all
 * recurring payments against that will be sent to URL1.
 *
 * Note that this also affects you if you were to move your CiviCRM instance to
 * another domain (if you do, get the webserver at the original domain to emit
 * a 307 redirect to the new one, PayPal will re-send).
 *
 * Therefore, for the sake of these old recurring contributions, CiviCRM should
 * maintain this script as part of core.
