the URL for the osCommerce handler that processes the transaction results for a payment.
on an unmodified osCommerce installation this will be [base URL]/catalog/checkout_process.php

Steps

Download the customized authorizenet_cc_sim.php file at the bottom of this article

Replace [installation root]/catalog/includes/modules/payment/authorizenet_cc_sim.php with the one downloaded in Step 1

Click on Modules on the left menu

Select the "Authorize.net Credit Card SIM" module

Install the module (if this has not been done previously)

Configure as in the screenshot below

Click update to complete the configuration

By default the customized authorizenet_cc_sim.php script is set to behave exactly the same as the original one, meaning payments are sent to Authorize.Net. To use E-xact's Hosted Checkout service, edit authorizenet_cc_sim.php to set the $exact_mode variable as described in the Receipting Options section.

Receipting Options

There is no Silent Post handler in the osCommerce source code, so a customized one would be needed to use this feature. See explanation in Zen Cart Receipting Options for details.

The data that is returned to osCommerce from E-xact is used to display and email customer receipts, as well as to update its own database. Additional actions may be performed as well depending on the configuration of osCommerce.

Payment Page

set Return Link Method (for receipt page) to POST

set Receipt Link URL to the checkout process URL

Relay Response

The option Pass HTTP Redirects to the Customer's Browser can be enabled, since osCommerce's checkout process handler does return a redirect (HTTP Status 302) to the destination page. The destination page would be [base URL]/catalog/checkout_success.php for a successful payment, or [base URL]/catalog/checkout_payment.php for a failed payment.
