The Ministry of Finance has released an updated version of the API of the National e-Invoice System (KSeF) – a test environment that supports the logical structures of FA(1) and FA(2) e-invoices, the ministry announced on Tuesday. The aim is to test the new solution by entities involved in the development of invoicing software. The tests enable the adaptation of IT systems to the implementation of the KSeF.
