This API is subject to change. Bug fixes and new features will be released based on developer feedback throughout the preview period.
Note: The Item Variants API only works with the Wix Restaurants Menus (New) app. Make sure you have installed this app from Wix App Market.
Updates an item variant.
To update multiple item variants at once, use Bulk Update Variants.
Each time an item variant is updated, revision increments by 1. The existing revision must be included when updating the variant. This ensures you're working with the latest variant information, and it prevents unintended overwrites.
You can only call this method when authenticated as a Wix app or Wix user identity.
