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.

I got it a perfect solution of my question

In addition to email notification, PayPal can send you the transaction data (also called Instant Payment Notification) to a specific url. With Instant Payment Notification, PayPal sends payment notification messages with encrypted code to the specified URL for each payment you receive. Follow the instructions below to setup Instant Payment Notification.

Go to the PayPal website and log in to your account.
Click “Profile” at the top of the page.
Click “Instant Payment Notification Preferences” in the Selling Preferences column.
Click “Edit IPN Settings.”
Enter the notification URL and select “Receive IPN messages.”
Click “Save.”

You can send customized emails from the Instant Payment Notification data. Please seehttp://paypaltech.com/SG2 for sample scripts.

we can customize sample script code according our need.
