AI-generated

Summary

Finds invoices for a client by their tax identification number (NIP), with optional date and offset filters. Returns the matching invoices as n8n items.

Inputs

  • Authentication (required) — Choose direct Fakturownia API keys or a fakto.app Bearer token.
  • Client Tax No (NIP) (required) — Client tax identification number.
  • Limit — Maximum number of results to return; defaults to 50 (allowed range 1–1000).
  • Additional Fields — Optionally filter by Date From and Date To (YYYY-MM-DD), or skip results with Offset.

Output shape

A list of invoice items, with each matching invoice returned as a separate n8n item.

An empty match produces no items. Offset is converted to a page using the limit, so it skips results in page-sized increments. With direct API key authentication, the node verifies the fakto.app subscription before running the operation.
