Catalog Item Variation

An item variation, representing a product for sale, in the Catalog object model. Each item must have at least one item variation and can have at most 250 item variations.

An item variation can be sellable, stockable, or both if it has a unit of measure for its count for the sold number of the variation, the stocked number of the variation, or both. For example, when a variation representing wine is stocked and sold by the bottle, the variation is both stockable and sellable. But when a variation of the wine is sold by the glass, the sold units cannot be used as a measure of the stocked units. This by-the-glass variation is sellable, but not stockable. To accurately keep track of the wine's inventory count at any time, the sellable count must be converted to stockable count. Typically, the seller defines this unit conversion. For example, 1 bottle equals 5 glasses. The Square API exposes the stockable_conversion property on the variation to specify the conversion. Thus, when two glasses of the wine are sold, the sellable count decreases by 2, and the stockable count automatically decreases by 0.4 bottle according to the conversion.

Structure

Catalog Item Variation

Fields

Name	Type	Tags	Description
item_id	str	Optional	The ID of the CatalogItem associated with this item variation.
name	str	Optional	The item variation's name. This is a searchable attribute for use in applicable query filters. Its value has a maximum length of 255 Unicode code points. However, when the parent item uses item options, this attribute is auto-generated, read-only, and can be longer than 255 Unicode code points.
sku	str	Optional	The item variation's SKU, if any. This is a searchable attribute for use in applicable query filters.
upc	str	Optional	The universal product code (UPC) of the item variation, if any. This is a searchable attribute for use in applicable query filters. The value of this attribute should be a number of 12-14 digits long. This restriction is enforced on the Square Seller Dashboard, Square Point of Sale or Retail Point of Sale apps, where this attribute shows in the GTIN field. If a non-compliant UPC value is assigned to this attribute using the API, the value is not editable on the Seller Dashboard, Square Point of Sale or Retail Point of Sale apps unless it is updated to fit the expected format.
ordinal	int	Optional	The order in which this item variation should be displayed. This value is read-only. On writes, the ordinal for each item variation within a parent CatalogItem is set according to the item variations's position. On reads, the value is not guaranteed to be sequential or unique.
pricing_type	str (Catalog Pricing Type)	Optional	Indicates whether the price of a CatalogItemVariation should be entered manually at the time of sale.
price_money	Money	Optional	Represents an amount of money. Money fields can be signed or unsigned. Fields that do not explicitly define whether they are signed or unsigned are considered unsigned and can only hold positive amounts. For signed fields, the sign of the value indicates the purpose of the money transfer. See Working with Monetary Amounts for more information.
location_overrides	List Item Variation Location Overrides	Optional	Per-location price and inventory overrides.
track_inventory	bool	Optional	If true, inventory tracking is active for the variation.
inventory_alert_type	str (Inventory Alert Type)	Optional	Indicates whether Square should alert the merchant when the inventory quantity of a CatalogItemVariation is low.
inventory_alert_threshold	long|int	Optional	If the inventory quantity for the variation is less than or equal to this value and inventory_alert_type is LOW_QUANTITY, the variation displays an alert in the merchant dashboard. This value is always an integer.
user_data	str	Optional	Arbitrary user metadata to associate with the item variation. This attribute value length is of Unicode code points. Constraints: Maximum Length: 255
service_duration	long|int	Optional	If the CatalogItem that owns this item variation is of type APPOINTMENTS_SERVICE, then this is the duration of the service in milliseconds. For example, a 30 minute appointment would have the value 1800000, which is equal to 30 (minutes) * 60 (seconds per minute) * 1000 (milliseconds per second).
available_for_booking	bool	Optional	If the CatalogItem that owns this item variation is of type APPOINTMENTS_SERVICE, a bool representing whether this service is available for booking.
item_option_values	List Catalog Item Option Value for Item Variation	Optional	List of item option values associated with this item variation. Listed in the same order as the item options of the parent item.
measurement_unit_id	str	Optional	ID of the ‘CatalogMeasurementUnit’ that is used to measure the quantity sold of this item variation. If left unset, the item will be sold in whole quantities.
sellable	bool	Optional	Whether this variation can be sold. The inventory count of a sellable variation indicates the number of units available for sale. When a variation is both stockable and sellable, its sellable inventory count can be smaller than or equal to its stockable count.
stockable	bool	Optional	Whether stock is counted directly on this variation (TRUE) or only on its components (FALSE). When a variation is both stockable and sellable, the inventory count of a stockable variation keeps track of the number of units of this variation in stock and is not an indicator of the number of units of the variation that can be sold.
image_ids	List[str]	Optional	The IDs of images associated with this CatalogItemVariation instance. These images will be shown to customers in Square Online Store.
team_member_ids	List[str]	Optional	Tokens of employees that can perform the service represented by this variation. Only valid for variations of type APPOINTMENTS_SERVICE.
stockable_conversion	Catalog Stock Conversion	Optional	Represents the rule of conversion between a stockable CatalogItemVariation and a non-stockable sell-by or receive-by CatalogItemVariation that share the same underlying stock.
