# About Item Modifiers

With the Item Modifiers API you can manage item modifiers. Item modifiers are extra menu [items](https://dev.wix.com/docs/api-reference/business-solutions/restaurants/menus/items/items/introduction.md) that can be applied additionally to the selected dish. For example, "Almond milk" could be an item modifier that can be applied to a coffee order. Item modifiers can be gathered into [groups](https://dev.wix.com/docs/api-reference/business-solutions/restaurants/menus/items/item-modifier-groups/introduction.md).

With the Item Modifiers API, you can:

- Create, update and delete item modifiers.
- Retrieve the information about the item modifier.

## Before you begin

It's important to note the following point before starting to code:

- The Item Modifiers API only works with the Wix Restaurants Menus app. Make sure you have installed this app from the [Wix App Market](https://www.wix.com/app-market/wix-restaurants-menus-new).

## Use cases

- [Sync pizza menus across all sites](https://dev.wix.com/docs/api-reference/business-solutions/restaurants/menus/items/item-modifiers/sample-use-cases-and-flows.md#sync-pizza-menus-across-all-sites)
