An attribute rides on a product tax code as a trailing component (a rented computer is `TANGIBLE_PERSONAL_PROPERTY._RENTAL`) and can change how a product is taxed. Each attribute carries its `group`; attributes sharing a group may be mutually exclusive. Pass `ptc` to narrow the list to the attributes worth offering on that code. The default page holds up to 1000 attributes — enough to return the whole list in one call today. To page, pass `starting_after` set to the `code` of the last item you received; `has_more` is true while more attributes remain. Each page carries a strong `ETag`; send it back as `If-None-Match` to get `304 Not Modified` when that page has not changed. See how to use it with code examples [here](/guides/using_products_apis)! ## OpenAPI ````yaml GET /product-attributes openapi: 3.1.0 info: title: Taxwire Public API version: 0.1.0 servers: [] security: [] paths: /product-attributes: get: tags: - Product Tax codes & Attributes summary: List Product Attributes description: >- Returns the attributes you can apply to your products, sorted alphabetically by code.
