v0.7.0 — KSeF authentication & readiness

Company onboarding to KSeF, platform-model authentication and an FA(3) XML generator aligned with the official schema.

March 15, 2026 KSeF

We've laid the foundation for KSeF: connect a company with a qualified certificate, manage permission contexts, and generate FA(3) XML that matches the official schema.

  • Platform-model KSeF authentication — owner, accountant and employee contexts
  • Challenge/response flow with SHA-256 signing — your private key never leaves the browser
  • Automatic token refresh and manual session revocation
  • FA(3) XML generator aligned with the official schema, with deterministic node ordering
  • Works against both KSeF test and production environments
  • Per-connection permission management
