Wildberries API TypeScript SDK / StockItem

Interface: StockItem

Defined in: types/products.types.ts:1005

A single stock record on a seller warehouse.

Migration deadline 2026-05-20 13:00 MSK: Wildberries is phasing out the sku field in favor of chrtId (size ID). Pass chrtId for all new code. The sku field will return HTTP 400 from the WB API after the deadline.

Exactly one of sku or chrtId should be set per item. If both are set, chrtId wins at the SDK level (the request will be sent with chrtId only).

Since

3.12.0

Properties

Property	Type	Description	Defined in
<a id="sku"></a> sku?	string	Deprecated since 3.12.0 — use chrtId instead. WB API will reject sku after 2026-05-20 13:00 MSK. See docs/guides/stocks-sku-to-chrtid-migration.md.	types/products.types.ts:1010
<a id="chrtid"></a> chrtId?	number	Size ID returned by POST /content/v2/get/cards/list. Casing note: WB API uses chrtID (uppercase D) in Content endpoints (/content/v2/get/cards/list) but chrtId (lowercase d) in this Marketplace stocks endpoint. Pass the same numeric value, but the SDK property is chrtId (lowercase d) for stocks methods. The SDK type keeps this optional for backwards compatibility, but the WB API will REQUIRE chrtId (and reject sku) after 2026-05-20 13:00 MSK. Since 3.12.0	types/products.types.ts:1023
<a id="amount"></a> amount?	number	Stock amount.	types/products.types.ts:1025
