# Developing in Sandbox Mode

> Test your LiveAvatar integration without consuming credits

Sandbox Mode is a development environment that lets you verify your integration without consuming credits.

## What you can do

* Verify API integration and session lifecycle
* Test frontend and backend connectivity
* Debug audio and video pipelines
* Iterate on your implementation for free

## Constraints

* **Limited avatars** — only the Wayne avatar is available (ID: `dd73ea75-1218-4ef3-92ce-606d5f7fbc0a`)
* **Short sessions** — sessions automatically terminate after approximately 1 minute
* **No credit usage** — Sandbox Mode does not require or consume any credits

## Enabling Sandbox Mode

Include the `is_sandbox` flag when creating a session token:

```bash theme={null}
curl -X POST https://api.liveavatar.com/v1/sessions/token \
  -H "X-API-KEY: <YOUR_API_KEY>" \
  -H "content-type: application/json" \
  -d '{
    "mode": "FULL",
    "is_sandbox": true,
    "avatar_id": "dd73ea75-1218-4ef3-92ce-606d5f7fbc0a",
    "avatar_persona": {
      "voice_id": "<voice_id>",
      "language": "en"
    }
  }'
```

<Info>
  Once your integration is working in Sandbox Mode, remove the `is_sandbox` flag and swap in your production avatar to go live.
