Cancel paypal subscription

I have successfuly create a paypal subscription with paypal subscription button and set it with IPN. So when the user cancel their subscription, I will know. Now how can I notify paypal to cancel their subcription when the user deactivate their account in his user subscription setting in my website.

Do it the other way around when canceling subscriptions. Rather than canceling on your site first, then passing the information to Paypal, create a Cancel Subscription button, like how to did for creating subscriptions (its in the More Options menu I think) and use similar IPNs to pass it to your website.

That make sense. But the client doesn’t want that. It troubles the customer. Isn’t there a way for this?
