> ## Agent Instructions
> H Platform has four products: the Agents API (managed computer-use agents, base URL https://agp.eu.hcompany.ai/api/v2 or https://agp.hcompany.ai/api/v2 for the US), the Models API (OpenAI-compatible Holo vision-language models at https://api.hcompany.ai/v1), HoloDesktop CLI (Holo on the user's own desktop), and HoloTab (a free no-code Chrome extension that runs Holo in the user's browser, with recordable routines and schedules).
> Authenticate with a bearer API key from the HAI_API_KEY environment variable. SDKs: `pip install hai-agents` (Python, `from hai_agents import Client`) and `npm install hai-agents` (TypeScript, `import { HaiAgentsClient } from "hai-agents"`). CLI: `hai`.
> Agents do work in a browser or on a desktop; describe the task as an imperative instruction. To run a task quickly, prefer the pre-built agent `h/web-surfer-flash`. Read results from the session's `latest_answer` after it reaches a terminal status.
> Sessions are the unit of work; wait for a terminal status (completed, failed, timed_out, interrupted) before reading the answer. Use webhooks or the `changes` long-poll endpoint to follow progress.

# Update an environment

> Replace the configuration of an environment in your catalog.

Updates an existing environment. This is a **full replacement** of the [Browser](/agents-api/browser/configuration) spec. The `id` must match the URL identifier: renames are not supported.

**Returns** the updated [Environment](/agents-api/environments/overview) object.

***

## Path parameters

<ParamField path="id" type="string" required>
  The environment's `id` (e.g. `wide-browser` or `myorg/wide-browser`). Slash-containing identifiers are supported.
</ParamField>

***

## Request body

A **full replacement** of the [Browser](/agents-api/browser/configuration) spec. The `id` in the body must equal the URL identifier. Any field you omit is reset to its default, not preserved, including `vault_id`: omitting it unbinds any [vault](/agents-api/vaults/overview) currently attached. To change individual fields without resending the rest, use [Patch](/agents-api/environments/patch) instead.

The example below binds a vault while keeping the rest of the spec.
