# Create Session

> Spawn a new browser

## Description

Creates a new browser and returns the browser ID used for all subsequent commands.

## Authentication

Open-source deployments do not require authentication by default. If your server config enables `X-API-Key`, include that header with the request.

## Request Body

*No request body required.*

## Response

<ResponseField name="execution_id" type="string">
  The browser ID. Pass this as `:id` in all subsequent command endpoints.
</ResponseField>

<Note>
  Store this value immediately; it is the handle used for navigation, commands, logs, and cleanup.
</Note>

## Example

```bash theme={null}
curl -X PUT http://localhost:8080/browsers/
