ksef-java-rest-client's Introduction

Sonarcloud Status Renovate enabled Maven Central

KSeF java REST client

KSeF

  • API version: 2.0.4
  • Build date: 2023-11-12
  • wspierana wersja schemy XML: FA (2)

Krajowy Systemu e-Faktur

Projekt sprawdzony produkcyjnie. Status: RC2.

Celem projektu jest stworzenie elastycznego klienta API KSeF na platformę Java, z wykorzystaniem popularnych bibliotek wywołań http i serializacji JSON. Obecnie zaimplementowany jest klient OkHttp OkHttpApiClient oraz JDK11+ HttpClient a także serializer Gson GsonJsonSerializer i Jackson.

Stabilne wersje są dostępne w Maven Central (nie ma potrzeby samodzielnego budowania ze źródeł): Maven Central

Pomoc w rozwoju projektu jest bardzo mile widziana.

Build Requirements

The project can be built on JDK11+, and stating from version 2.0.13, we will stop supporting JDK8 at all. The last JDK8 compatible version was 2.0.12.

Building the API client library requires:

  1. Java 11+
  2. Maven
