LinkedIn Poster

Post text updates to your LinkedIn profile directly from OpenClaw.

Features

• OAuth 2.0 authentication (one-time setup)
• Automatic token management (60-day expiry)
• Works via command line or WhatsApp
• Production-ready callback server

Setup

1. LinkedIn App Configuration

1. Create a LinkedIn app at LinkedIn Developers
2. Add redirect URL: https://linkedin-oauth-server-production.up.railway.app/callback
3. Request access to "Share on LinkedIn" and "Sign In with LinkedIn" products
4. Copy your Client ID and Client Secret

2. Environment Variables

Add to your openclaw.json:

{
  "plugins": {
    "env": {
      "LINKEDIN_CLIENT_ID": "your_client_id",
      "LINKEDIN_CLIENT_SECRET": "your_client_secret"
    }
  }
}

3. First Run Authorization

The first time you use the skill, it will:

1. Open a browser for LinkedIn authorization
2. Save the access token locally
3. Use the saved token for future posts

Usage

Via WhatsApp

Send a message to OpenClaw:

post to linkedin: Just shipped a new feature! 🚀

Or:

share on linkedin: Excited to announce our new product launch!

Via Command Line

node skills/linkedin-poster/runner.cjs "Your message here"

Posting to a Company Page

To post to a LinkedIn Company Page where you are an admin:

node skills/linkedin-poster/runner.cjs "Company update!" --org "My Company Name"

The skill will fuzzy search your administered organizations and post to the best match.

Note: You must have the w_organization_social permission (Marketing API/Company Page Management) enabled in your LinkedIn App settings for this to work.

How It Works

1. First use: Opens browser → Authorize → Token saved
2. Subsequent uses: Uses saved token → Posts immediately
3. Token expiry: Auto-prompts for re-authorization after 60 days

OAuth Callback Server

This skill uses a hosted callback server at: https://linkedin-oauth-server-production.up.railway.app

The server handles OAuth callbacks securely and works for anyone using the skill.

Troubleshooting

"redirect_uri does not match"

Ensure https://linkedin-oauth-server-production.up.railway.app/callback is added to your LinkedIn app's Redirect URLs.

"Authorization timeout"

The skill waits 60 seconds. Try again and authorize faster.

"Token expired"

Run the skill again - it will automatically start a new OAuth flow.
