# How to Manage Inventory Items

In this document, you’ll learn how to manage inventory items using the admin APIs.

## Overview

Using the inventory items admin REST APIs, you can manage inventory items and inventory levels in your store.

### Scenario

You want to add or use the following admin functionalities:

- Manage inventory items. This includes listing, creating, updating, and deleting items.
- Manage inventory levels. This includes creating, updating, and deleting inventory levels.

---

## Prerequisites

### Medusa Components

It is assumed that you already have a Medusa backend installed and set up. If not, you can follow the [quickstart guide](../../../development/backend/install.mdx) to get started.

### Required Module

This guide assumes you have the Inventory module installed on your Medusa backend. If not, you can learn how to install it using [this guide](../install-modules.md#inventory-module).

Furthermore, inventory levels are tied to a location ID. So, it’s recommended to use the [Stock Location module](../install-modules.md#stock-location-module) if you don’t have any location logic implemented in place.

### JS Client

This guide includes code snippets to send requests to your Medusa backend using Medusa’s JS Client, among other methods.

If you follow the JS Client code blocks, it’s assumed you already have [Medusa’s JS Client](../../../js-client/overview.md) installed and have [created an instance of the client](../../../js-client/overview.md#configuration).

### Medusa React

This guide also includes code snippets to send requests to your Medusa backend using Medusa React, among other methods.

If you follow the Medusa React code blocks, it's assumed you already have [Medusa React installed](../../../medusa-react/overview.mdx) and have [used MedusaProvider higher in your component tree](../../../medusa-react/overview.mdx#usage).

### Authenticated Admin User

You must be an authenticated admin user before following along with the steps in the tutorial.

You can learn more about [authenticating as an admin user in the API reference](https://docs.medusajs.com/api/admin#authentication).

---

## List Inventory Items

You can list inventory items by sending a request to the [List Inventory Items endpoint](https://docs.medusajs.com/api/admin#inventory-items_getinventoryitems):

<Tabs groupId="request-type" isCodeTabs={true}>
<TabItem value="client" label="Medusa JS Client" default>

```ts
medusa.admin.inventoryItems.list()
.then(({ inventory_items }) => {
  console.log(inventory_items.length)
})
```

</TabItem>
<TabItem value="medusa-react" label="Medusa React">

```tsx
import { useAdminInventoryItems } from "medusa-react"

function InventoryItems() {
  const { 
    inventory_items,
    isLoading } = useAdminInventoryItems()

  return (
    <div>
      {isLoading && <span>Loading...</span>}
      {inventory_items && !inventory_items.length && (
        <span>No Items</span>
      )}
      {inventory_items && inventory_items.length > 0 && (
        <ul>
          {inventory_items.map(
            (item) => (
              <li key={item.id}>{item.id}</li>
            )
          )}
        </ul>
      )}
    </div>
  )
}

export default InventoryItems
```

</TabItem>
<TabItem value="fetch" label="Fetch API">

```ts
fetch(`<BACKEND_URL>/admin/inventory-items`, {
  credentials: "include",
})
.then((response) => response.json())
.then(({ inventory_items }) => {
  console.log(inventory_items.length)
})
```

</TabItem>
<TabItem value="curl" label="cURL">

```bash
curl -L -X GET '<BACKEND_URL>/admin/inventory-items' \
		 -H 'Authorization: Bearer <API_TOKEN>'
```

</TabItem>
</Tabs>

This endpoint does not require any path or query parameters. You can, however, pass path parameters to search or filter inventory items. For example, you can get inventory items in a specific location by passing the `location_id` query parameter. You can learn more about available query parameters in the [API reference](https://docs.medusajs.com/api/admin#inventory-items_getinventoryitems).

This request returns an array of inventory item objects.

## Create an Inventory Item

:::tip

Inventory items are automatically created when a variant is created with `manage_inventory` set to `true` or updated to enable the `manage_inventory` attribute. So, in general cases, you don’t need to create an inventory item manually.

:::

You can create an inventory item by sending a request to the [Create Inventory Item endpoint](https://docs.medusajs.com/api/admin#inventory-items_postinventoryitems):

<Tabs groupId="request-type" isCodeTabs={true}>
<TabItem value="client" label="Medusa JS Client" default>

```ts
medusa.admin.inventoryItems.create({
  variant_id,
})
.then(({ inventory_item }) => {
  console.log(inventory_item.id)
})
```

</TabItem>
<TabItem value="medusa-react" label="Medusa React">

```tsx
import { useAdminCreateInventoryItem } from "medusa-react"

const CreateInventoryItem = () => {
  const createInventoryItem = useAdminCreateInventoryItem()
  // ...

  const handleCreate = () => {
    createInventoryItem.mutate({
      variant_id,
    })
  }

  // ...
}

export default CreateInventoryItem
```

</TabItem>
<TabItem value="fetch" label="Fetch API">

```ts
fetch(`<BACKEND_URL>/admin/inventory-items`, {
  credentials: "include",
  method: "POST",
  headers: {
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    variant_id,
  }),
})
.then((response) => response.json())
.then(({ inventory_item }) => {
  console.log(inventory_item.id)
})
```

</TabItem>
<TabItem value="curl" label="cURL">

```bash
curl -L -X POST '<BACKEND_URL>/admin/inventory-items' \

		 --data-raw '{
           "variant_id": "variant_123"
     }'
```

</TabItem>
</Tabs>

This endpoint requires in the body parameter the `variant_id` parameter, which is the ID of the variant to create this inventory item for. You can also pass other inventory-related parameters, such as `sku`. You can learn more about other available parameters in the [API reference](https://docs.medusajs.com/api/admin#inventory-items_postinventoryitems).

This request returns the created inventory item as an object.
