The "URL isn't a valid LinkedIn article" error appears when the URL you entered doesn't match LinkedIn's post format, specifically when it doesn't contain "posts" in the URL path or doesn't lead directly to the standalone post page. Valid LinkedIn post URLs follow this format: https://www.linkedin.com/posts/[username]/[post-details]-activity-[activity-id]. To get a valid URL, open the LinkedIn post, click the three-dot menu, and select "Copy link to post," then paste this into your Phantom's input.
Why you're seeing this
This error appears when the LinkedIn URL you entered does not match the expected post format required by the Phantom.
→ For example, the LinkedIn Auto Commenter, which only accepts direct post URLs.
Common causes include:
- The URL doesn't lead to the standalone LinkedIn post page (e.g., it links to the user's activity feed or another page instead).
- The URL doesn't contain the word "posts", which is required for valid post URLs.
When the URL structure doesn't match LinkedIn's post format, the Phantom cannot identify or open the post during the run.
How to fix it
Check the URL format
A valid LinkedIn article URL follows this format:
https://www.linkedin.com/posts/[username]/[post-details]-activity-[activity-id]
If the URL you entered doesn't match this pattern, it's likely a post URL, a profile URL, or a feed URL, none of which the Phantom can process.
Copy the URL from LinkedIn's Share button
The safest way to get a valid article URL is to copy it directly from LinkedIn:
- Open the LinkedIn post.
- Click the three-dot menu in the top-right corner of the post.
- Select Copy link to post.
-
Paste this URL into your Phantom input.
Use the LinkedIn Activity Extractor
If you're working with multiple posts or aren't sure your links are correct:
- Run the LinkedIn Activity Extractor to export valid post URLs.
- Use those exported URLs as input for the LinkedIn Auto Commenter or any other automation requiring direct post links.
