n8n RSS to Twitter/X Threads + LinkedIn Posts with Groq

Turn fresh RSS articles into an X (Twitter) thread + LinkedIn post every hour—automatically with Groq in n8n

This n8n workflow monitors an RSS feed, pulls newly published articles, uses Groq (via LangChain) to write both a Twitter/X thread and a LinkedIn post, then publishes to X and LinkedIn—while logging everything in Google Sheets for safe, trackable automation.

What this workflow does

• Runs hourly using a scheduled trigger to check for new RSS items.
• Loads configuration such as the RSS feed URL, Google Sheets ID, and hashtag settings.
• Prevents duplicates by comparing each RSS item link against a Google Sheets log.
• Fetches full article text by loading the article webpage and extracting the main content using an HTML CSS selector.
• Generates content with Groq (LangChain): produces a structured output containing:
  • an X (Twitter) thread (multiple tweets)
  • a LinkedIn post
• Validates X character limits to ensure every generated tweet fits within 280 characters.
• Safe handling for failures: if any tweet is too long, it logs the full tweet list to a “NeedsReview” Google Sheet instead of posting.
• Publishes when valid: posts the X thread one tweet at a time as replies, then publishes the LinkedIn update, and records the article in the “Processed” sheet.

Use cases

• SaaS teams turning weekly industry updates into consistent X threads and LinkedIn engagement.
• Automation engineers streamlining content repurposing from RSS sources without manual writing.
• Operators who want audit-friendly publishing with Google Sheets logs and review queues.

Technical details

• Integrations/credentials: Google Sheets, X (Twitter), LinkedIn, and Groq (Chat Model).
• Nodes / building blocks: if, set, code, html, twitter, linked in.
• Assistive logic: LangChain-based Groq generation and tweet validation before posting.

Setup note: Create a Google Sheets document with two tabs (by default “Processed” and “NeedsReview”) and configure the workflow’s sheet names and columns to match your logging needs.
