Endpoint Playground

Try the Chewy Product Attributes API

Returns Chewy's own specification table for up to 20 products in one call, keyed by part number -- the structured attribute list (lifestage, pet type, product type, material, made-in country, packaging type, flavor, defining size, plus long-form key-benefits and cautions copy), together with the handling and compliance flags that govern how an item ships (pharmaceutical, prescription vet-diet, frozen, refrigerated, single-tablet, gift card), its bundle structure and component SKUs, its autoship eligibility/discount and preset reorder cadence, its merchandising classification path, and the numeric category group ids it belongs to (each usable directly as chewy_category's group_id). This complements rather than repeats chewy_products and chewy_product: price, rating, images, reviews, and descriptions stay on those endpoints, and the attribute table is not available from either. Use the group parameter to return a single attribute group. Part numbers Chewy does not recognize are reported in not_found; if none of them resolve the response is a 404.

Response behavior

- `items[].attributes[]` is the structured specification table. Each entry has an `identifier` (Chewy's own attribute key, e.g. `LitterMaterial`, `Lifestage`, `MadeIn`, `KeyBenefits`), its `group` and `usage`, and one or more `values`. An attribute can carry several values -- `Lifestage` is commonly `["All Lifestages", "Adult"]`. A typical SKU returns 25-35 attributes. - The handling and compliance flags -- `is_pharmaceutical`, `is_vet_diet`, `is_frozen`, `is_refrigerated`, `is_single_tablet`, `is_gift_card` -- govern how an item ships and whether it needs veterinary authorization. `is_vet_diet` is `true` for prescription-diet foods. These are omitted when false. - `items[].category_group_ids` is the list of numeric category group ids the item belongs to. Each is directly usable as `/chewy/category`'s `group_id`, so this is a reverse index from a SKU back to every category listing that contains it. - `items[].merch_class_identifiers` is Chewy's merchandising classification path, e.g. `["f2-cat-consumables", "f2-cat-consumables-litter", ...]`, ordered broad to narrow. - `items[].preset_frequency` is the item's default autoship cadence, e.g. `{"unit":"WEEK","value":5}`. `unit` is one of `DAY`, `WEEK`, `MONTH`. - Bundle products carry `is_bundle` plus `bundle_items[]` listing the component SKUs; `is_bundle_multi_sku` and `is_bundle_same_sku` distinguish the two bundle kinds. - Part numbers Chewy does not recognize are returned in `not_found` rather than as null entries -- upstream silently drops them. If none of the requested part numbers resolve, the response is a `404`. - Per-product promotion/deal detail is deliberately not exposed here; it requires customer context upstream and is unavailable to an anonymous caller.
