One row per invoice with its debit notes, refunds, credit notes, completed payments and applied advance payments listed under it as sub-rows, and the net position the page prints: Net = (Amount + Debit) - Returns. Credit notes linked to no invoice are standalone rows (they reduce Amount) unless hide_credit_notes is on. Newest invoice first; one block per currency, with a Totals row for each.Mirrors /owner/reports/report/invoice_net_position.The report has no grouping, no ordering control and no summary view. It is not paginated.Refused, not ignored: parameters this endpoint does not offer, including the page's display and export controls, are a 400 naming the parameter.Bounded: a request matching more invoices than the endpoint can return in one response is a 400, never a partial report.
