Total amount for the debit transaction.
This property should contain the total amount to be removed from a debit card for a Sale, including any optional CashBack amount. (eg, for a sale for $10 with a cash back of $20 TransactionAmount must contain "3000"). The TransactionAmount also specifies the total amount to Credit back to a debit card.
This amount is to be presented with an implied decimal point. For example, US $10.00 must be represented as 1000, and $0.10 is likewise simply 10. The allowable number of significant digits as well as the positioning of any implied decimal point is dictated by the designated CurrencyCode configuration setting. In the United States (default), the number of allowable significant digits is seven. Thus the maximum TransactionAmount is "9999999", yielding a US dollar amount of $99,999.99. This field may not contain a negative number.
