| amount_money | Money | The amount of money to refund. This amount cannot be more than the `total_money` value of the payment minus the total amount of all previously completed refunds for this payment. This amount must be specified in the smallest denomination of the applicable currency (for example, US dollar amounts are specified in cents). For more information, see Working with Monetary Amounts. The currency code must match the currency associated with the business that is charging the card. | |

This amount is specified in the smallest denomination of the applicable currency (for example, US dollar amounts are specified in cents). The value cannot be more than the `amount_money`. You can specify this parameter in a refund request only if the same parameter was also included when taking the payment. This is part of the application fee scenario the API supports.
