Fisver Proxy Service
If your existing program that you need to integrate with the Fiscal Registry is not written in Java, then Fisver Proxy is the best pick for you!
Fisver Proxy installed on one of your internal servers will mediate between your application and the Fiscal Registry. It takes care of proper message formatting and signing, and even handles multiple keys in cases of several merchants.
You just have to modify your existing application to communicate with the Fisver Proxy using a simple TCP/XML (REST) protocol.
Installation
Install Java JRE 7 or higher, unpack the Fisver Proxy application, andcopy private merchant keys into proper directory.
You can also configure a custom port and other parameters, but this is already enough for a quick start.
Integration
You just have to modify your existing application to communicate with the Fisver Proxy using a simple TCP/XML (REST) protocol. The simplified XML messages containing invoice details will be automatically signed and verified.
Portability
Fisver Proxy can work on any platform capable of running Java.
Macintosh, Windows/PC, Linux, Unix - they are all supported!
The application runs also on Windows XP with Java 8.
