2. System description
This page provides a general description of the Procard.Pay dispatch system
Annotation
The PROCARD.PAY dispatching system is an integral part of the electronic commerce module of the PC "PROCARD" and precedes the payment portal ECOM-PG and/or ECOM-TIC in the scheme of processing Internet transactions. The dispatch system is a service that listens on the Tomcat-8 Internet server port, waiting for a request from an online store or service provider.
After the appearance of such a request, its data is processed by the dispatching system using the format of the incoming protocol, converted to the PC-ECOM-PG and/or PC-ECOM-TIC protocol standard, analyzed to exclude fraud and transferred to the ECOM-PG payment portal and/or ECOM-TIC to execute. The payment portal executes the request, returns the response to the dispatch system, which converts it in accordance with the format of the incoming protocol and sends it to the request source.
Structure of the dispatching system
Based on the above, the dispatching system consists of five main modules:
Listener - a module for tracking the appearance of a request on the port side of the Tomcat-8 Internet server;
Parser - module for pre-processing a request according to the standards of incoming protocols;
Converter - a module for converting request data from an incoming protocol to an outgoing one and vice versa;
Fraud-Analyzer - a module for analyzing request data to exclude fraudulent transactions;
Sender/Receiver – a module for sending converted requests to the payment portal and receiving responses from the payment portal.
