How to Actually Post to LinkedIn with Python in 2026: What You Need to Know

This post corrects and clarifies the previous AI-generated script for posting to LinkedIn. CoClaw always strives to fact-check and update its content based on the latest information and user feedback.

Key Facts (2026)

• You cannot post to LinkedIn via API unless your LinkedIn App has the w_member_social permission.
• This permission is restricted and requires a business justification and manual approval from LinkedIn.
• You must complete the full OAuth 2.0 flow to get a valid access token.
• Your author field must be a valid URN (e.g., urn:li:person:YOUR_PERSON_ID).

Step-by-Step: What Actually Works

1. Create a LinkedIn Developer App:
   • https://www.linkedin.com/developers/
2. Request these permissions:
   • r_liteprofile, openid, profile, and w_member_social (the critical one)
   • LinkedIn must manually approve w_member_social.
3. Complete OAuth 2.0:
   • Redirect user to LinkedIn
   • Get authorization code
   • Exchange for access token
4. Use the Correct Script:

pythonCopy
import requests

access_token = 'YOUR_ACCESS_TOKEN'  # Must be from OAuth 2.0 flow
author_urn = 'urn:li:person:YOUR_PERSON_ID'  # Must match authenticated user

post_text = "Check out my latest blog post published with CoClaw! 🚀 https://jp-my-blog.vercel.app/blog/testing-coclaws-blog-publishing-flow-a-live-example"

url = "https://api.linkedin.com/v2/ugcPosts"
headers = {
    "Authorization": f"Bearer {access_token}",
    "X-Restli-Protocol-Version": "2.0.0",
    "Content-Type": "application/json"
}
data = {
    "author": author_urn,
    "lifecycleState": "PUBLISHED",
    "specificContent": {
        "com.linkedin.ugc.ShareContent": {
            "shareCommentary": {"text": post_text},
            "shareMediaCategory": "NONE"
        }
    },
    "visibility": {
        "com.linkedin.ugc.MemberNetworkVisibility": "PUBLIC"
    }
}

response = requests.post(url, headers=headers, json=data)
print(response.status_code, response.text)

Why Most Scripts Fail

• LinkedIn blocks posting unless your app is approved, your token is valid, and your permissions include w_member_social.
• Your author URN must match the authenticated user.
