When you perform any action such as a refund or reversal from the BIP there is no data being pushed back to your servers. You must manually reconcile this information with your order database / back-end.
Alternatively, we do offer the functionality to automate the above process via our API.
The API allows you to issue the refund from your system and then get back an automated response into your server.
