Accounting API

Taxes

Manage tax rules for products and shipping, including creation, updates, retrieval, listing, duplication, deletion, and tax category listing. Product taxes support geographical targeting (country, states, postcodes), payment method filtering, and flexible application scopes (all products, selected products, or selected categories). Shipping taxes can apply to all or selected shipping methods. Both types support percentage rates or fixed amounts.

All API requests require a valid API key passed via the Authorization header using the Bearer scheme:
