# Update Agent

> Change an agent's display name.

### Overview

Changes an agent's display name. The agent's configuration lives in its versions, not on the agent record; to change behavior, save a new version with [Create Agent Version](https://docs.bland.ai/api-v2/post/agents-id-versions.md).

Requires an admin, owner, operator, or prompter role.

### Headers

**authorization** `string` *required*

Your API key for authentication.

### Path Parameters

**agent\_id** `string` *required*

The agent's unique identifier.

### Body Parameters

**name** `string` *required*

New display name. Must be non-empty after trimming whitespace. Returns `400 INVALID_NAME` otherwise.

### Response

**data** `object`

The updated agent record. Environments are not included; use [Get Agent](https://docs.bland.ai/api-v2/get/agents-id.md) for those.

**agent object**

**id** `string`
