- On October 15, the Ministry of Finance launched the pre-production (Demo) environment for the KSeF 2.0 API.
- The environment allows financial-accounting systems to be tested using real authentication methods and production-like conditions.
- Integration with the KSeF 2.0 API is necessary for compatibility with the mandatory KSeF 2.0 system.
- The Demo environment uses real authentication data, mirrors production-level data protection, but issuing invoices here has no legal effect.
- Technical support is available on business days from 7:00 to 19:00 via the KSeF contact form.
