linkitin 0.1.2

LinkedIn automation library - post, fetch, and search via Voyager API

linkitin

Python library for LinkedIn automation via the Voyager API. Fetch posts, search content, and publish — all through an async client.

macOS only — login_from_browser() requires macOS and Chrome. The login_with_cookies() path works cross-platform.

Install

pip install linkitin

Requires Python 3.10+.

Development

python -m venv .venv
source .venv/bin/activate
pip install -e ".[dev]"

Authentication

Chrome proxy mode (recommended — requires macOS and Chrome logged into LinkedIn):

async with LinkitinClient() as client:
    await client.login_from_browser()  # routes API requests through Chrome via AppleScript

Chrome 145+ uses App-Bound Encryption for cookies, making them inaccessible to external tools. login_from_browser() works around this by executing API requests inside Chrome's LinkedIn tab, which automatically includes all session cookies. Requires "Allow JavaScript from Apple Events" enabled in Chrome (View > Developer).

Manual cookie input (if you have raw li_at and JSESSIONID values):

async with LinkitinClient() as client:
    await client.login_with_cookies(li_at="AQED...", jsessionid="ajax:123...")

Cookies from manual input are saved to disk and reused on subsequent runs via login_from_saved().

Usage

import asyncio
from linkitin import LinkitinClient

async def main():
    async with LinkitinClient() as client:
        # Authenticate
        if not await client.login_from_saved():
            await client.login_from_browser()

        # Fetch your posts
        posts = await client.get_my_posts(limit=10)
        for p in posts:
            print(p.text[:80], f"({p.likes} likes)")

        # Search posts
        results = await client.search_posts("AI startups", limit=5)

        # Get home feed
        feed = await client.get_feed(limit=20)

        # Get trending posts
        trending = await client.get_trending_posts(topic="AI", period="past-week", limit=5)

        # Create a text post
        urn = await client.create_post("Hello LinkedIn!", visibility="PUBLIC")

        # Create a post with image
        with open("chart.png", "rb") as f:
            urn = await client.create_post_with_image(
                text="Check out these metrics!",
                image_data=f.read(),
                filename="chart.png",
            )

        # Schedule a post (automatically rounded to next 15-min slot)
        from datetime import datetime, timezone, timedelta
        urn = await client.create_scheduled_post(
            text="Scheduled post — hello future!",
            scheduled_at=datetime.now(timezone.utc) + timedelta(hours=2),
        )

        # Comment on a post
        feed = await client.get_feed(limit=5)
        comment_urn = await client.comment_post(feed[0].urn, "Great post!")

        # Reply to a comment (threaded)
        reply_urn = await client.comment_post(
            feed[0].urn, "Thanks!", parent_comment_urn=comment_urn
        )

        # Repost a post from the feed
        repost_urn = await client.repost(feed[0].share_urn)

        # Repost with your thoughts
        repost_urn = await client.repost(feed[0].share_urn, text="Great insights!")

asyncio.run(main())

Configuration

LinkitinClient accepts optional parameters to override defaults:

client = LinkitinClient(
    cookies_path="~/.myapp/linkedin_cookies.json",  # default: ~/.linkitin/cookies.json
    timezone="America/New_York",                     # default: detected from system
    timezone_offset=-5.0,                            # default: computed from system
    display_width=1440,                              # default: 1920
    display_height=900,                              # default: 1080
    user_agent="Mozilla/5.0 ...",                    # default: modern Chrome/macOS UA
)

Rate Limiting

All requests go through a token-bucket rate limiter: 10 requests per minute with 1-5 second random jitter between requests. On 429/403 responses, exponential backoff kicks in starting at 30 seconds.
