        In a sale or authorization transaction, the `surcharge` field specifies a fee amount that a consumer is charged in addition to the transaction amount. The fee amount is also added into `amount.total`. For example, if the transaction request had `amount.total = 100` and the `surcharge.percentage` was 1.5% the transaction would include `amount.total = 101.50` and `amount.surcharge = 1.50`
