## Overview {#overview}

Refund use cases allow the debtor service providers to provide refund account information for the debtor to the creditor service provider and request refund confirmation from the creditor service provider.   

## Refund Account Request {#refund-account-request}

The refund account request service allows the debtor service provider to provide the debtor account details (or debtor service provider holding account details) to the creditor service provider for initiating a refund to the debtor.
