title: how i come to know if cancel subscription from Paypal site
body: <p>I have integrated PayPal merchant account to the website , m doing it for a client
  People can sign up to the website after subscribing and hence paying thru PayPal .we have recurring payments. But if people unsubscribe from the site their access to the site is closed but my issue is if people don't click the unsubscribe on the site but just cancel the recurring payment from their own PayPal accounts how would I cancel their subscription on the site.
  Please suggest some PHP code or idea to cancel the subscription.</p>
  
  <p>Thanks in Advance, vikas tyagi</p>
