# UpdateVariant

# Package: items

# Namespace: VariantsService

# Method link: https://dev.wix.com/docs/api-reference/business-solutions/restaurants/menus/items/item-variants/update-variant.md

## Permission Scopes:
Manage Restaurants - all permissions: SCOPE.RESTAURANTS.MEGA-SCOPES

## Introduction

> **Note:** The Item Variants 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).

Updates an item variant.

To update multiple item variants at once, use [Bulk Update Variants](https://dev.wix.com/docs/rest/business-solutions/restaurants/menus/item-variant/bulk-update-variants.md).

Each time an item variant is updated, its 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.

### Examples

### Update a variant
```javascript
import { itemVariants } from "@wix/restaurants";

const variantId = "02042f01-58ab-441c-b5db-55f51c855a11";

const variant = {
  _id: "02042f01-58ab-441c-b5db-55f51c855a11",
  revision: "1",
  name: "Medium"
};

async function updateVariant() {
  const response = await itemVariants.updateVariant(variantId, variant);
}

/* Promise resolves to:
 * {
 *   "_id": "02042f01-58ab-441c-b5db-55f51c855a11",
 *   "revision": "2",
 *   "name": "Medium"

 */

```

### updateVariant (self-hosted)
Self-hosted SDK calls require you to [create a client](https://dev.wix.com/docs/sdk/articles/work-with-the-sdk/about-the-wix-client.md).

```javascript
import { createClient } from '@wix/sdk';
import { itemVariants } from '@wix/restaurants';
// Import the auth strategy for the relevant access type
// Import the relevant host module if needed

const myWixClient = createClient ({
  modules: { itemVariants },
  // Include the auth strategy and host as relevant
});


async function updateVariant(_id,variant) {
  const response = await myWixClient.itemVariants.updateVariant(_id,variant);
};
```
