New unitOfMeasure values in orders API Selection object

On 2026-02-23, the Selection object in the orders API will include new enumerated values for the unitOfMeasure value. The unitOfMeasure value indicates the unit of measure used to weigh, determine size, or otherwise quantify a menu item selection for a sale.

Make sure your orders API integration will handle new unitOfMeasure values before they appear in production orders API response data on 2026-02-23. For more information about the orders API Selection object, see API reference documentation.

Note

Your integration should handle unexpected values in any Toast API enumerated value without disrupting operations.
