Tax Classes V3

Create, update, and delete tax classes. Tax classes group products and shipping methods so you can apply different tax rates to each.

This API uses batch operations for POST, PUT, and DELETE. Successful responses use the envelope format { "data": ..., "meta": ... }, with POST and PUT returning an array of tax class resources under data. DELETE is filter-based: pass the id:in query parameter to specify which tax classes to remove — there is no single-resource delete on this endpoint.
