Post blog articles to LinkedIn and Twitter with OpenAI captions and UploadToURL

Turn your blog into a self-driving social media machine. This workflow monitors your RSS feed, extracts new content, and uses AI to craft platform-perfect posts for LinkedIn and Twitter/X, complete with hosted images.

🎯 What This Workflow Does

This workflow automates the transition from "published on blog" to "live on social" in three primary stages:

🔁 Step 1 — RSS Trigger & Filter

• RSS Feed Trigger: Polls your blog every 15 minutes to detect new articles
• Validation: Ensures each item has a title and cover image before proceeding

☁️ Step 2 — Media Hosting Bridge

• Fetch Binary: Downloads the blog’s cover image
• UploadToURL: Uploads the image to a public CDN and returns a stable URL for social platforms

🤖 Step 3 — AI Multi-Platform Posting

• OpenAI Captions: Generates:
  • LinkedIn → professional, long-form post
  • Twitter/X → short, punchy tweet with hashtags
• Parallel Publishing: Posts simultaneously to both platforms
• Success Logging: Tracks hosted image URLs and caption details

✨ Key Features

• Built-in Deduplication: RSS ensures no duplicate posts
• Clean Data Processing: Strips HTML for better AI output
• Fallback Logic: Uses default caption if AI fails
• Reliable Media Hosting: UploadToURL ensures public image access
