Recurring Payments Notifications

Recurring Payments Notifications
You are notified of recurring payments events through IPN and email; however, using
GetTransactionDetails to obtain the information you need is typically sufficient.
You are notified of certain events through IPN. For recurring payments profiles created using
Express Checkout, buyers are also notified of specific events by email. The following table
indicates when IPN and emails are generated.
Recurring payments IPN messages and email
NOTE: API transactions such as ManangeRecurringPaymentsProfileStatus do not
trigger IPN notification because the success or failure of the call is immediately
provided by the API response.
