ISO8583 Issuing Gateway

General description

ISO8583 HTTP Gateway (Gateway) has been developed according to ISO8583 Native host-to-host Interface specification for processing issuing direction messages received from card suite solution and transform them to HTTP REST calls to pre-configured web-hook using JSON payload. In other words, it enables issuing customers to communicate with the Processing using REST service.

Gateway starts a new thread that listens on the configured server port and forwards all the non-technical messages to the customer in JSON format.
