dvcrn 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
- Create a LinkedIn app at LinkedIn Developers
- Add redirect URL:
https://linkedin-oauth-server-production.up.railway.app/callback - Request access to "Share on LinkedIn" and "Sign In with LinkedIn" products
- 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:
- Open a browser for LinkedIn authorization
- Save the access token locally
- 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
- First use: Opens browser → Authorize → Token saved
- Subsequent uses: Uses saved token → Posts immediately
- 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.
