eProcessing Network

eProcessing Network is payment service that allows US-based businesses to process credit card transactions. The eProcessing Network add-on for Shopp provides a seamless onsite checkout experience where the customer stays on your website throughout the checkout process.

Getting Started

Before you can use the eProcessing Network add-on for Shopp, you will need a eProcessing Network account. Use the Merchant Information Request Form to begin setting up your account.

Web Hosting Setup

Since the eProcessing Network payment gateway for Shopp uses an onsite checkout process, sensitive information (such as credit card numbers) may be entered on your website. In order to protect your customer’s information your website’s hosting service will need SSL Setup & Certificates.


  • Uncompress the add-on files
  • Upload the folder (directory) and all its contents to your Shopp add-ons folder (directory) under: .../wp-content/shopp-addons


When your eProcessing Network account is approved and successfully set up, you will need to locate the eProcessing Network Account Number and the Restrict Key.

To setup Shopp to use eProcessing Network, login to your website’s WordPress Admin and navigate to ShoppSetupPayments.

  • Payment Gateway
    Select eProcessing from the Payment Gateway menu and click the Add Payment Option button.
  • Option Name
    Enter a custom label for the payment option as you would like it to appear on your store front (such as Credit Card).
  • Supported Cards
    Select the payment cards your site will accept for processing.
  • Account Number
    Enter your eProcessing Network Account Number.
  • Restrict Key
    Enter the Restrict Key for your eProcessing Network account.

Be sure to save your changes.


Your eProcessing Network account may need to have the Transparent Database Engine (TBDE) to prevent the “Blocked” error during checkout:

Blocked (1)

This error occurs when using the Authorize.net Emulation setting instead of enabling the TDBE (Transparent Database Engine) because the eProcessing Network add-on for Shopp use the TBDE integration, not Authorize.net emulation.
