# set_cookies

> Uploads cookies to the session

<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>

Accepts either cookies (list of dicts) or cookie\_file (json file path) as argument.

{/* @sniptest testers/sessions/upload_cookies_simple.py */}

```python upload_cookies.py theme={null}
from typing import Any

from notte_sdk import NotteClient

# Upload cookies for github.com to automatically login
cookies: list[dict[str, Any]] = [
    {
        "name": "sb-db-auth-token",
        "value": "base64-cookie-value",
        "domain": "github.com",
        "path": "/",
        "expires": 9778363203.913704,
        "httpOnly": False,
        "secure": False,
        "sameSite": "Lax",
    }
]

client = NotteClient()
with client.Session() as session:
    _ = session.set_cookies(cookies=cookies)  # type: ignore[arg-type]  # can also set cookie_file="path/to/cookies.json"
    session.execute(type="goto", url="https://github.com/nottelabs/notte")
```

## Parameters

<ParamField path="cookies" type="UnionType[list[CookieDict], None]" default="None">
  The list of cookies (can be obtained from session.get\_cookies)
</ParamField>

<ParamField path="cookie_file" type="UnionType[str, Path, None]" default="None">
  The path to the cookie file (json format)
</ParamField>

## Returns

[`SetCookiesResponse`](/sdk-reference/misc/setcookiesresponse.md): The response from the upload cookies request.

## Raises

* `ValueError`: If both cookies and cookie\_file are provided, or if neither is provided.
* `ValueError`: If the session hasn't been started yet (no session\_id available).
