Automate LinkedIn Medium Posts with n8n & Airtable Integration

What this workflow does

This workflow automatically posts new Medium articles about Android development to LinkedIn twice a day at 9 AM and 7 PM.
It prevents posting the same article twice by checking an Airtable database.
It sends notifications via Telegram each time a post is published.
This saves time and avoids repeated content.

Who should use this workflow

This workflow is for content marketers or social media managers who post Medium articles on LinkedIn.
It fits those who want to automate posting schedule and keep posts unique.

Common issues and how to handle them

Empty article lists or no posts

Usually caused by wrong or missing RapidAPI key or no new articles matching tags.
Check API keys and test Medium API separately.

LinkedIn posting errors

Often due to expired or invalid OAuth2 tokens.
Reconnect LinkedIn credentials and verify posting permissions.

Duplicate articles posted

Occurs if Airtable is not updated or filter logic fails.
Check that new article IDs are saved in Airtable and filter compares IDs correctly.

• Change posting times by editing cron expression in Schedule Trigger.
• Add more tags in the JavaScript array inside get random tags node for variety.
