KSeF token

The token is generated once, by hand, in the KSeF taxpayer app (Aplikacja Podatnika KSeF). Each environment has its own instance and its own tokens.

1. Log in to the taxpayer app of the chosen environment (addresses below).
2. Open the "Tokeny" tab and choose "Generuj token".
3. Select the InvoiceWrite (submitting) and InvoiceRead (listing and downloading) permissions.
4. Copy the token. The app shows it only once.

Pass the token in an environment variable:

export KSEF_TOKEN='...'
