# CreateStockItem

> Creates a new item that is a stock item from the start, so that its stock is managed in warehouses. Takes the same properties as POST /v2/items, except for three: the optional storageConstraints block is replaced by a mandatory stockManagement block, images are not part of this request - assign them with PATCH /v2/items/{itemId} once the item exists - and salesChannels is not either, activate channels with POST /v2/items/{itemId}/sales-channels/{salesChannelId}/activate. Use POST /v2/items/{itemId}/stock-items/convert to turn an item that already exists into a stock item.

If a request with this mutation's Idempotency-Key was already completed, the response's `extensions` contains an `idempotency.{responseName}` entry with `wasReplayed: true`.
