Draft Invoice Lines Products

If you maintain a Product catalog with Product Pricings, these endpoints let you create Draft Invoice Lines that reference a specific pricing instead of supplying every field yourself — Fenerum templates the line from the product (price, currency, VAT settings, revenue group).

Compared to the regular Draft Invoice Line endpoints, these lines also accept first-class discount fields: discount_percentage, discount_fixed_per_quantity, and discount_fixed_total (mutually exclusive).
