Log into your Foxycart shopping cart administration:

  3. Next click the box to accept credit or debit cards.
  4. Select Payeezy / First Data Global Gateway e4 from the Gateway drop down list.
    • Note: You may select Authorize Only if you do not wish to capture the funds (a Purchase). However, you will have to go to the GGe4 Real-time Payment Manager (RPM) in order to perform the Auth Completion transaction. This is generally not the desired behavior, so only enable this if you know what you're doing.

In order to complete the remaining fields, you will need to retrieve information from First Data Global Gateway e4.

  1. Log in to your First Data Global Gateway e4 Real-time Payment Manager Account to retrieve your Gateway ID and Password.
  2. Under Administration choose Terminals and select the terminal you will be using for your FoxyCart account. The Details tab contains your Gateway ID and Password.

  4. Enter the Gateway ID and Password into the Test Gateway ID and Test Gateway Password fields in FoxyCart test store settings.
    • Note: If your account has multiple terminals associated with it, select the terminal that is identified as the eCommerce (ECOMM) terminal type.
  5. Select the API Access tab from the terminal manager navigation and generate New Key link to get a new HMAC Key.
  6. Enter the Key ID, a 3-6 digit number, into the Test Key ID and the newly created HMAC key and into Test HMAC Key field.
    • Note that if you generate a new HMAC key, that you need to click the “update” button at the bottom of the “API Access” tab for that key to be saved against the terminal.
  7. Once you've entered all four values in the FoxyCart administration's payment section, scroll down and select the Update Payment Gateway button. You will now be connected to the GGe4 payment gateway.
