Using Decimals and Strings

Cybersource

uses decimal points in all amount and tax rate fields;

Cybersource

does not use implied decimal points. For example, if the amount of the product being purchased is 29.95, set that field to

29.95

.

Barclays

does not support fractional quantities. You must use whole numbers only. For tax rates used with Level III transactions, you must include a decimal point in the value. For example, if a tax rate is 1%, you should set that field to

1.00

.

For many of the fields described in this document, Visa and Mastercard permit different lengths for alphanumeric (string) input.

Cybersource

accepts any length you provide. If the value you provide is longer than the payment card company permits,

Cybersource

truncates the value, keeping the left-most portion of the value. If the value you provide is shorter than the payment card company requires,

Cybersource

pads the field before sending it to the processor.
