Automate WordPress Blog Publishing to Medium with n8n

What This Workflow Does

This workflow checks a WordPress blog homepage for new posts, gets each post's title and content, and then posts that content automatically to Medium. It saves hours of manual copying and stops mistakes like missing images or links.

The workflow fetches the blog page, finds post titles and links, loads each post's full content, extracts key parts like the title and introduction, and publishes these as new posts on Medium.

Tools and Services Used

• WordPress Blog URL: Public blog page for fetching posts.
  
• n8n Automation Platform: Runs the workflow with various nodes like HTTP Request, HTML extractors, and Medium node.
  
• Medium API: Posts content directly to Medium using API credentials.
