New feature v0.7.0
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
