# Payment Refund The refund functionality allows merchants to return the amount paid by the customer via a QR code. Refunds are only available for payments that have been successfully processed. **Refund Types** * **Full Refund**\ The entire amount paid by the customer is returned. * **Partial Refund**\ A partial amount paid by the customer is returned. **Technical Considerations** * Refunds are only available for transactions that were successfully completed. * Refunds can only be initiated by the merchant, either via API or through the dedicated banking platform. * A reason for the refund must be specified. * Refunds can be tracked through the transaction status returned in the API response. > **Important**: Refunds are irreversible. Once processed, the amount is automatically returned to the customer's account, in accordance with the issuing bank's policies. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
