# Validate install sandbox configuration

`POST /install/sandbox/test`

Validates the browser-install sandbox-provider selection without persisting it. For Daytona, performs a cheap authenticated call against the Daytona SDK to verify the API key. For Docker, returns ok without further checks. Requires the one-time install token.

## Request body

- InstallSandboxInput — Sandbox provider selected during browser install. `api_key` is required for Daytona and ignored for Docker. `allow_local` enables the local sandbox provider alongside the selected runtime; it defaults to true when omitted.
  - `provider` 'docker' | 'daytona', required
  - `api_key` string
  - `allow_local` boolean

## Response `200`

Sandbox configuration validated successfully

- InstallSandboxValidationResponse — Successful response from install-time sandbox validation.
  - `ok` boolean, required

## Other responses

- `401` — Invalid or missing install token
- `422` — Sandbox validation failed

## Changes

- **2026-06-02** `0d0a9e145028` — 1 info
  - added the new optional request property `allow_local`
