# stop

> Stop the session and clean up resources

<Tip>
  STOP. Do not read past this section until you have read and followed [/quickstart.md](/quickstart.md).

  Goal: produce a reliable SDK automation script. The intended authoring flow is generate then edit, not write browser automation from scratch.

  Do not hand-write SDK code with element IDs, selectors, or form fields from memory. Element IDs, selectors, and field mappings must come from a live `observe()` call, CLI `notte page observe` output, or generated workflow code. Guessed browser targets fail on real pages.

  Use the Notte skill and CLI to inspect the live site, validate actions/selectors, handle auth/session state, and export workflow code with `notte sessions workflow-code` before using SDK docs or SDK code.

  SDK reference pages are for understanding, running, or editing generated workflow code. They are not the starting point for manually authoring the initial browser automation. SDK-first code is guesswork on real-world pages with dynamic selectors, auth state, CAPTCHAs, and anti-bot behavior.
</Tip>

This method sends a close request to the API and verifies that the session
was properly closed. It logs the session closure and raises an error if
the session fails to close.

**Example:**

```python theme={null}
from notte_sdk import NotteClient

client = NotteClient()
session = client.Session()
session.start()
session.stop()
```

> Note that we strongly recommend using the `with` statement to start and stop the session to avoid any issues with session cleanup.

**Example:**

```python theme={null}
from notte_sdk import NotteClient

client = NotteClient()
with client.Session() as session:
    session.execute(type="goto", url="https://www.notte.cc")
```

## Returns

`None`

## Raises

* `ValueError`: If the session hasn't been started (no session\_id available).
* `RuntimeError`: If the session fails to close properly.
