A new feature has been added to the SIMPLer system that allows users to view Authorization/Approval Codes returned from the payment gateway to the SIMPLer system. This feature is limited to a small group of users. In order to allow user view authorization codes, they have to had "customers->payment authorization codes" user rights enabled (Fig. 1).
Fig.1. User Rights
Authorization Codes are saved each time CC or E-check transaction takes place (EUP Payment, Captive Portal Payment, SIMPLer CC / E-check Payment, Auto-Payment).
NOTE: This is currently enabled for IPPay and Authorize.NET. If it does not work for your payment gateway, please contact firstname.lastname@example.org to discuss integration.
Authorization/Approval Codes can be viewed from Invoices->Payment Authorization Codes link (Fig. 2) - all customers or from customer details page - quick links section (Fig. 3).
Example page is displayed below (Fig. 4)
