Invoices

Updates invoice taxes

Changed on Nov 3, 2026

Recalculates or replaces tax lines on an existing invoice using the supplied tax payload. Use after changing taxable addresses or when integrating an external tax engine result. Returns 400 when the supplied taxes would turn an invoice total that is zero or positive into a negative total. Invoices whose total is already negative can still be updated.
