fakturownia-invoice-minimal

To create a minimal invoice payload for the Fakturownia API, you provide known client_id and product_id values to generate the smallest valid JSON required, optionally including seller department or recipient IDs.

Automated Fakturownia invoice creation requires a client_id and product_id, while seller department and recipient IDs are optional fields you can include to further refine the JSON payload.

The Fakturownia API does not require an explicit issue date for automated invoice creation, as the minimal payload relies on the API's default issue date handling and payment_to_kind settings.

You can generate batch invoice JSON payloads using known client and product IDs by repeatedly applying the minimal payload construction, reducing friction for automated single or batched workflows.

You should avoid using a minimal invoice payload when your workflow lacks existing client_id or product_id references, as this approach skips manual object construction and relies on identifiers already available in your system.
