After the Payment
After the payment is completed, the Mobile Payments Library returns the payKey. A number of
other features are also available to you to enable you to further deal with the payment: Instant
Payment Notification, Transaction Details, and Refunds.
Instant Payment Notification
Instant Payment Notification (IPN) is PayPal’s message service that sends a notification when a
transaction is affected. You can integrate IPN with your systems to automate and manage your
back office. More details and documentation are available at: www.paypal.com/ipn
Transaction Details
You can integrate with the PayPal PaymentDetails API to retrieve details on a payment based
on the payKey. More details and documentation are available at:

of the Refund API. More details and documentation are available at:
