# Partial refund

Use the **issueRefund** method to issue a partial refund for an order processed by 2Checkout.

## Requirements

* The payment for the refundable order needs to be collected.
* You cannot issue a refund for an amount higher than the total order amount.
* We recommend you create a new order with **placeOrder** to have one that can be refunded.
* The order’s status must be ’COMPLETE’ and it should have a `TotalPrice` > 0.
* The `OrderDate` cannot be older than a year from the current date.
* To obtain the `LineItemReference`, use the **getOrder** method: [Retrieve an order](/json-rpc-api-reference/json-rpc-api-6.0/api-requests/retrieve-an-order.md)
