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 Modifier Groups API only works with the Wix Restaurants Menus (New) app. Make sure you downloaded this app from Wix App Market.
Updates multiple item modifier groups at once. This function supports partial updates. Each time a modifier group is updated, its revision increments by 1. The existing revision must be included when updating an item modifier group. This ensures you're working with the latest item information, and prevents unintended overwrites. Up to 100 modifier groups can be returned per request.
You can only call this method when authenticated as a Wix app or Wix user identity.
This method doesn’t return any custom errors, but may return standard errors. Learn more about standard Wix errors.
