Shopping
Cart Variables
A list of the HTML form variables used by the shopping cart when processing transactions
through the Authorize Net payment gateway the using SIM (Simple Integration Method).
All of the following variables are automatically inserted by the shopping cart into the
order form displayed to the user. No changes to the html code are required by the
merchant.
To change the values, use the shopping cart
setup program. Click on Setup 3 and then select Authorize Net. After making the changes,
save the shop.pl file and upload this to your server.
x_login
This is same as the Login ID used to access the Authorize Net Merchant interface.
x_show_form
This field tells the server to use the gateway's own secure payment form, to collect the
customers name, address and payment details. The layout of this form can be altered using
the merchant control panel.
x_amount
This is the total value of the order inclusive of shipping and sales tax or VAT.
x_description
Summary of the items order including individual pricing, plus any postage and tax
if included in the total.
Long_Description
This is a custom variable unique to this shopping cart, and is
only used when the description is more than 255 characters long. A summary of the
transaction is still posted to the order form, but the rest of the details are sent to the
merchant and customer by email.
x_version
This indicates to the server the set of fields that is available in the server
response. The shopping cart uses version 3.1 which allows the merchant to use the card
code CVV2/CVC2/CID) feature. This is the three or four digit security code that can be
found on the back of most credit cards in the signature panel. American Express
cards carry this on the front. This provides an extra layer of security for the
transaction.
x_test_request
This puts the shopping cart in test mode. This allows the merchant to test
the shopping cart without any actual credit cards been used. No money changes hands and no
cards are debited. All order forms and emails are clearly marked test transaction. All
Authorize Net accounts are initially placed in test mode before been made live by their
user support. |
