Instant Payment Notification

Instant Payment Notification (IPN) is a notification mechanism that uses HTTP POST to send you immediate updates on transactions. IPN saves you the trouble of polling Amazon FPS for transaction results that complete asynchronously.

Amazon FPS sends you an IPN whenever a transaction completes, as in the following cases:

A token is created successfully
A token is canceled successfully
A payment or reserve succeeds
A payment or reserve fails
A payment or reserve goes into a pending state
A reserved payment is settled successfully
A reserved payment is not settled successfully
A refund goes into a pending state
A refund succeeds
A refund fails
A payment is canceled
A reserve is canceled

	Note
IPN must be configured in order to operate. If IPN is not configured, an e-mail message is the only notification made. For information on configuring IPN, see Setting Up Instant Payment Notification.
