STOP. Do not read past this section until you have read and followed /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.

Sessions provide a comprehensive set of browser actions for interacting with web pages. All actions are executed through session.execute().

---

Fetch

Issue an HTTP request from the page the session is on. session.fetch(url) runs the browser’s own fetch() inside the current page, so the request carries the page’s cookies, the session’s proxy and the browser’s network fingerprint. A relative URL resolves against the current page, which also keeps it same-origin; a cross-origin URL is subject to CORS as in any browser tab, so goto the target origin first. The result is a standard requests.Response: status_code, ok, headers, text, url, json() and raise_for_status() work as usual.

fetch.py

from notte_sdk import NotteClient

client = NotteClient()

with client.Session() as session:
    session.execute(type="goto", url="https://en.wikipedia.org/wiki/Main_Page")
    # fetch runs inside the page: same cookies, proxy and fingerprint as the browser
    response = session.fetch("/api/rest_v1/page/summary/Main_Page")
    response.raise_for_status()
    summary = response.json()

Parameters:

• url (str): The URL to request, absolute or relative to the current page
• method (str): HTTP method, GET by default
• headers (dict): Extra request headers
• params (dict): Query parameters appended to the URL
• json (Any): Body serialised as JSON with an application/json content type
• data (str | dict): Body sent verbatim, or form-encoded when a dict
• timeout (float): Seconds before the request is aborted

Use for: Calling a site’s own JSON endpoints with the session’s cookies and IP, without leaving the browser

Action Patterns

Chaining Actions

Execute multiple actions in sequence:

action_chaining.py

from notte_sdk import NotteClient

client = NotteClient()

with client.Session() as session:
    # Navigation
    session.execute(type="goto", url="https://example.com/login")

    # Form filling
    session.execute(type="fill", selector="input[name='email']", value="[e-mail]")
    session.execute(type="fill", selector="input[name='password']", value="password123")

    # Submission
    session.execute(type="click", selector="button[type='submit']")

    # Wait for redirect
    session.execute(type="wait", time_ms=2000)

    # Verify success
    content = session.scrape()
    print(content)

Error Handling

Handle action failures:

error_handling.py

from notte_sdk import NotteClient

client = NotteClient()

with client.Session() as session:
    session.execute(type="goto", url="https://example.com")

    # Don't raise on failure
    result = session.execute(type="click", selector="button.maybe-exists", raise_on_failure=False)

    if result.success:
        print("Button clicked successfully")
        session.execute(type="click", selector="button.next")
    else:
        print(f"Click failed: {result.message}")
        # Try alternative approach
        session.execute(type="click", selector="button.alternative")

Conditional Actions

Execute actions based on conditions:

conditional_actions.py

from notte_sdk import NotteClient

client = NotteClient()

with client.Session() as session:
    session.execute(type="goto", url="https://example.com")

    # Check if element exists
    result = session.execute(type="click", selector="button.optional", raise_on_failure=False)

    if result.success:
        # Element was there and clicked
        session.execute(type="click", selector="button.next")
    else:
        # Element wasn't there, skip
        print("Optional button not found, continuing...")

Selector Strategies

CSS Selectors

Most flexible and commonly used:

css_selectors.py

from notte_sdk import NotteClient

client = NotteClient()

with client.Session() as session:
    session.execute(type="goto", url="https://example.com")

    # By ID
    session.execute(type="click", selector="#submit-button")

    # By class
    session.execute(type="click", selector=".btn-primary")

    # By attribute
    session.execute(type="click", selector="button[type='submit']")

    # By combination
    session.execute(type="click", selector="form#login button.submit")

    # By nth-child
    session.execute(type="click", selector="ul li:nth-child(2)")

Direct Attributes

Use direct attribute parameters when available:

direct_attributes.py

from notte_sdk import NotteClient

client = NotteClient()

with client.Session() as session:
    session.execute(type="goto", url="https://example.com")

    # Pseudo observe output: [B1] button "Submit"
    # Only use IDs that appear in your live observe() output.
    session.execute(type="click", id="B1")

    # By selector
    session.execute(type="click", selector="button[type='submit']")

    # By placeholder selector
    session.execute(type="fill", selector="input[placeholder='Enter email']", value="[e-mail]")

    # By ARIA label selector
    session.execute(type="click", selector="button[aria-label='Close dialog']")

Best Practices

Prefer stable selectors:

stable_selectors.py

from notte_sdk import NotteClient

client = NotteClient()

with client.Session() as session:
    session.execute(type="goto", url="https://example.com")

    # Good - uses ID (stable)
    session.execute(type="click", id="submit-btn")

    # Good - uses data attribute
    session.execute(type="click", selector="button[data-testid='submit']")

    # Avoid - fragile position-based
    session.execute(type="click", selector="div > div > button:nth-child(3)")

Use specific selectors:

specific_selectors.py

from notte_sdk import NotteClient

client = NotteClient()

with client.Session() as session:
    session.execute(type="goto", url="https://example.com")

    # Good - specific
    session.execute(type="fill", selector="form#login input[name='email']", value="[e-mail]")

    # Less specific - might match wrong element
    session.execute(type="fill", selector="input", value="[e-mail]")

Common Workflows

form_submission.py

from notte_sdk import NotteClient

client = NotteClient()

with client.Session() as session:
    session.execute(type="goto", url="https://example.com/contact")

    session.execute(type="press_key", key="Enter")
    session.execute(type="wait", time_ms=2000)

    results = session.scrape(instructions="Extract search results")
    print(results)

Multi-Tab Workflow

    # Open multiple tabs
    session.execute(type="goto", url="https://site1.com")
    session.execute(type="goto_new_tab", url="https://site2.com")
    session.execute(type="goto_new_tab", url="https://site3.com")

    # Extract from each tab
    for tab_index in range(3):
        session.execute(type="switch_tab", tab_index=tab_index)
        data = session.scrape()
        process_data(data)

File Upload and Download

file_upload_download.py

from notte_sdk import NotteClient

client = NotteClient()

with client.Session() as session:
    session.execute(type="goto", url="https://example.com/upload")

    # Upload file
    session.execute(type="upload_file", selector="input[type='file']", file_path="/path/to/document.pdf")
    session.execute(type="click", selector="button.submit")

    # Wait for processing
    session.execute(type="wait", time_ms=3000)

    # Download result
    result = session.execute(type="download_file", selector="a.download")
    print(f"Downloaded: {result}")
