Using osCommerce with the Fast Charge Payment Gateway

The following instructions describe how to configure your osCommerce shopping cart to use the Fast Charge gateway.


The Authorize.Net Emulator allows merchants to use the Authorize.Net payment module that is available in most third party shopping carts. Simply change the ‘POST TO’ URL within the Authorize.Net payment module to point to Fastcharge’s gateway and your account will be up and running within a few minutes.


Locate the Authorize.Net Aim Payment Module in your shopping cart (/your web directory/catalog/includes/modules/payment/) and change the ‘POST TO’ URL FROM: https://secure.authorize.net/gateway/transact.dll TO: https://trans.secure-fastcharge.com/cgi-bin/authorize.cgi Depending on the shopping cart and it’s payment module you may need to change the post to URL in 1,2,3 or 4places. It’s best to find the AIM payment module and then change it everywhere in this file.

Here’s a tip, do a search in the AIM file for “.dll” to help you find the Authorize.net urls to replace with the emulator url.

Admin Settings:

Login to your Admin Panel and open the “Payment Methods” setting for Authorize.Net. If it gives you a choice select the AIM module because this will allow customers to stay on your site when they purchase from you. Once you get to the settings you can enter the following information:

  • API Login ID: This is your Fastcharge Account ID (FCXXX)
  • Transaction Key: This is your Fastcharge “Merchant Pin”
  • Mode: We always suggest “Live Mode”
  • Gateway URL: If you have this option enter https://trans.secure-fastcharge.com/cgi-bin/authorize.cgi
  • MD5 Hash: We now ignore this but you can enter “7gt77lyst555r7677yt”
  • Authorize or Capture: We recommend you select Authorize and Capture

NOTE: 99% of the calls we receive when you get to this point and cannot get a test transaction to go through is because of your Fast Charge fraud settings. You may need to adjust these setting under FRISK Configure in Fast Charge.

These are some of the most common carts that the emulator has been proven to work on:

WordPress + Shopp
Zen Cart

There are thousands of shopping carts and ecommerce systems that allow you to use the emulator and if you have any questions or need help please give us a call at (800) 757 5453.
