Mustangserver provides a REST-API for the java based Mustangproject.
Documented in OpenAPI, the Swagger Editor can be used to generate Clients in 56 programming languages.
You can try the functionality as usual via Postman, which can also import the OpenAPI definition, but also with the interactive HTML-Client, which also shows how the request would look like as curl command.
It can be hosted in house, or as a service on a German server, authentication via oAuth and with solid API management which includes possible later load balancing and possibilities to on the fly transform request/responses if required.
The following Mustang functionality is available:
- Extraction of XML from ZF1, ZF2 or FX
- Extraction of a JSON invoice from ZF1, ZF2 oder FX
- Combination of XML or JSON-invoices with PDF/A-1-files to FX/ZF
- Conversion of JSON-invoices into XML, e.g. for XRechnung
- Conversion of XML from UN/CEFACT CII to UBL
- Validation / Verification of ZF1, FF2, FX, XR-invoices or OrderX-orders
The advantage vis a vis the command line version is of course the availability over the network, JSON capabilities, the possibility to transform requests and responses, independence from a Java runtime and the speed: Users reported they “felt it was 50% faster” than the command line version.
Mustangserver is implemented in Spring Boot, for the in house version you could choose between Docker, a runnable Jar-file with embedded Jetty-HTTP-Server and a Web-Archive (WAR) file, which you can deploy on many servlet containers.
