What is ksef2?

ksef2 is a Python SDK for Poland's KSeF 2.0 API, the national e-invoicing system rolling out in 2026. It handles authentication via XAdES certificates or tokens, opens sessions for sending/querying/exporting invoices, and manages AES/RSA encryption transparently. Install via pip or uv on Python 3.12+, and get type-safe Pydantic models with context managers for sessions.

Why is it gaining traction?

Full 100% coverage of all 77 KSeF endpoints sets it apart from partial wrappers on ksef 2 github—send invoices, download UPOs, query metadata, even manage permissions and limits. Session resume via JSON serialization suits long-running exports in workers, plus test env helpers generate self-signed certs. Pythonic API with httpx and structlog logging feels native, beating raw REST calls.

Who should use this?

Polish ERP devs integrating KSeF for 2026 compliance, accounting SaaS builders automating invoice batches, or fintechs querying/exporting e-faktury. Ideal for backend teams handling high-volume invoicing in production, demo, or test environments.

Verdict

Solid pick for KSeF 2.0 integrations despite 24 stars and 1.0% credibility score—excellent docs, integration tests, and API coverage make it production-ready now. Grab it if you're in Poland's invoicing space; watch for community growth.
