HTML Variables for Subscribe Buttons

HTML variables for Subscribe buttons set the terms of subscriptions and their recurring

payments.

handling_cart is used in multiple Add to Cart buttons,

the handling_cart value of the first item is used.

item_name Required Name of the item or a name for the entire Shopping Cart

paymentaction Optional Indicates whether the transaction is payment on a final sale or

an authorization for a final sale, to be captured later.

Allowable values:

z sale

z authorization

z order

The default value is sale. Set the value to authorization

to place a hold on the PayPal account for the authorized

amount. Set the value to order to authorize the transaction

without placing a hold on the PayPal account.
