title: How to allow users to cancel their paypal subscription on the site, instead of going thru paypal CP?
body: <p>I have read thru their API (https://cms.paypal.com/us/cgi-bin/?cmd=_render-content&amp;content_ID=developer/e_howto_api_ECRecurringPayments), but I dont fully understand how to use it.</p>
  
  <p>Are there any PHP examples on how to utilize this? I use IPN + express checkout to create subscriptions.</p>
