Include a set of required variables and any optional variables from the table above for each 

item included in your buyer's cart. The first item included in the cart should be defined 

with parameters ending in _1, such as item_name_1, amount_1, and so on. Similarly, the 

second item should be denoted with variables like item_name_2, amount_2, and so on. 

IMPORTANT:

The _

x

 values must increment by one continuously in order to be recognized. 

If you skip from item #1 to item #3 without defining an item #2, the third item 

will be ignored.

8.1 HTML for Passing Individual Item Detail to PayPal

To specify currency: All monetary variables (amount_x, shipping_x, shipping2_x, 

handling_x, tax_x, and tax_cart) are interpreted in the currency designated by the 

currency_code variable posted with the payment. Because currency_code is not item 

specific, there is no need to append _

x

 to the currency_code variable name. If no 

currency_code variable is posted, all monetary values default to U.S. Dollars. 

To specify cart wide tax: Use the tax_cart variable to specify a tax amount that applies to 

the entire purchase, rather than to individual items. The tax_cart variable overrides any per 

item tax amount specified with tax_

x

.
