Use this property to determine how much money to transfer out of the user’s account and apply to the payment. Payment amounts may reflect a specific monetary amount or may indicate that the user should pay all or a portion of the bill. When resolving the transaction amount, always provide as much detail as you can. For example, if the user asked to pay the minimum amount of a credit card bill, your resolution should also contain the precise amount of money to pay.
