# 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](/api-v2/post/agents-id-versions).

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

### Headers

<ParamField header="authorization" type="string" required>
  Your API key for authentication.

### Path Parameters

<ParamField path="agent_id" type="string" required>
  The agent's unique identifier.
</ParamField>

### Body Parameters

<ParamField body="name" type="string" required>
  New display name. Must be non-empty after trimming whitespace. Returns `400 INVALID_NAME` otherwise.
</ParamField>
