Poland launches public consultation on KSeF 2.0 API business event model

  • Poland’s Ministry of Finance has launched a public consultation on its KSeF 2.0 API development, proposing a new model for handling invoice-related business events and synchronizing changes within the national e-invoicing platform.
  • The proposal introduces storing additional business data as separate, trackable events associated with invoices (rather than overwriting statuses), preserving a history of changes and allowing the current invoice state to be derived from these events.
  • The consultation, open until May 8, 2026, details examples of these events (e.g., invoice creation, payment, abuse reports) and outlines proposed API extensions for reading and recording these new business events.
