Getting started

To fetch your invoices from KSeF, Księguś needs a KSeF token. You can generate one yourself in a few minutes.

How to get a KSeF token

The video is one minute long and has no sound. The captions are in Polish, like the KSeF app itself. The steps are written out below.

  1. Go to ksef.podatki.gov.pl and click Przejdź do Aplikacji Podatnika KSeF 2.0 (go to the KSeF 2.0 taxpayer app).
  2. Sign in through login.gov.pl (mObywatel, your bank or Profil Zaufany) or with a certificate.
  3. Enter the company's NIP and click Przejdź dalej (continue).
  4. In the menu on the left, click Tokeny (tokens).
  5. Click Generuj token (generate token).
  6. Enter a name, for example Księguś. Tick wystawianie faktur (issuing invoices) and przeglądanie faktur (viewing invoices), then click Generuj token at the bottom of the page.
  7. Copy the token straight away. KSeF shows it only once.
  8. In Księguś, open Settings → Connections, paste the token and click Save token.

If you lose the token, generate a new one the same way.
