## Introduction

Updates a benefit item.

Each time the benefit item is updated,
`revision` increments by 1.
The current `revision` must be passed when updating the benefit item.
This ensures you're working with the latest benefit item
and prevents unintended overwrites.

### Examples

### updateItem
```javascript
import { items } from '@wix/benefit-programs';

async function updateItem(_id,item) {
  const response = await items.updateItem(_id,item);
};
```

### updateItem (with elevated permissions)
```javascript
import { items } from '@wix/benefit-programs';
import { auth } from '@wix/essentials';

async function myUpdateItemMethod(_id,item) {
  const elevatedUpdateItem = auth.elevate(items.updateItem);
  const response = await elevatedUpdateItem(_id,item);
}
```

### updateItem (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 { items } from '@wix/benefit-programs';
// Import the auth strategy for the relevant access type
// Import the relevant host module if needed

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


async function updateItem(_id,item) {
  const response = await myWixClient.items.updateItem(_id,item);
};
```
