# Retrieve an item attribute

Operation ID: `getItemAttribute`

Group: Inventory › Item Attributes

[Open in the interactive reference](https://docs.api.lensing.ai/lensing/v1/endpoints/getItemAttribute)

`GET /inventory/item-attributes/{id}`

Read-only: Reads and returns; changes nothing.

Retrieves an item attribute. The same fields come back from GET inventory/item-attributes. The item's code and the attribute's name are returned beside their identifiers, so a row can be rendered without three further calls.

## Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `Api-Version` | header | string · v1 | yes | The API version this request targets, named by its public identifier. Required on every request; omitting it, or naming a version this company does not have, is answered with 400. This document describes version `v1`. |
| `id` | path | string | yes | The unique identifier for the item attribute to read. |

## Response

`200` Success

Under `data` (getItemAttributeOutput):

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `id` | string | yes | The unique identifier for the item attribute. Example: `"9f2c1d77-5b41-4e0a-9a33-8c5d2e61b704"`. |
| `itemId` | string | yes | The identifier of the item carrying the attribute. See id on GET inventory/items/:id. Example: `"5f21c8b0-9d34-4a76-8e12-04b93c7de5a8"`. |
| `itemCode` | string | no | The item's code, for example 'WIDGET-01'. Echoed so the row can be rendered without reading the item. Example: `"WIDGET-01"`. |
| `attributeId` | string | yes | The identifier of the attribute definition, for example the one named 'Colour'. Example: `"c7a84f92-1e63-4d55-b0a1-6f7e3b9c2d48"`. |
| `attributeName` | string | no | The attribute's name, for example 'Colour'. Example: `"Colour"`. |
| `valueId` | string | no | The identifier of the chosen value. Absent when the attribute has been assigned without a value. Example: `"2b6d0e14-8f77-4a91-95c3-1d4e8a7f6b03"`. |
| `value` | string | no | The chosen value's text, for example 'Red'. Absent when the attribute has been assigned without a value. Example: `"Red"`. |
