Paypal Billing Agreement Cancellation

Question

To cancel a Billing Agreement created by a customer, Paypal gives an API which METHOD=BillAgreementUpdate to cancel a billing agreement. But when a user cancels the agreement by logging into his account, how do we find this out?

Does paypal send a notification when the agreement is cancelled or is there any API call we could use to check whether the agreement exists or not? I couldn't find any information about any such notifications from searching on google.

Answer 1

Take a look at Instant Payment Notification (IPN) . It'll give you what you want.

Answer 2

Paypal does not give any IPN if user cancels billing agreement. It can only be identified by error thrown when corresponding API call is made.
