  33  * This script processes "Instant Payment Notifications" (IPNs).  Modern
  34  * Payment Processors use the /civicrm/payment/ipn/123 endpoint instead (where
  35  * 123 is the payment processor ID), however a quirk in the way PayPal works
  36  * means that we need to maintain this script.
  37  *
  38  * Note on PayPal.
  39  *
  40  * Using PayPal Website Standard (which uses the old PayPal button API) the IPN
  41  * endpoint is passed to PayPal with every transaction, and it is then stored
  42  * by PayPal who unhelpfully do not give you any way to retrieve or change
  43  * this.
  44  *
  45  * This means that if you provide URL1 when setting up a recurring
  46  * contribution, then you will always need to maintain URL1 because all
  47  * recurring payments against that will be sent to URL1.
  48  *
  49  * Note that this also affects you if you were to move your CiviCRM instance to
  50  * another domain (if you do, get the webserver at the original domain to emit
  51  * a 307 redirect to the new one, PayPal will re-send).
  52  *
  53  * Therefore, for the sake of these old recurring contributions, CiviCRM should
  54  * maintain this script as part of core.
