n8n RSS to X, LinkedIn & Facebook Auto Cross-Posting

Auto cross-post new RSS articles to X, LinkedIn, and Facebook—every 15 minutes

Get a reliable RSS-to-social publishing pipeline with this n8n RSS to X, LinkedIn & Facebook Auto Cross-Posting workflow. It checks your RSS feeds on a 15-minute schedule, formats each new item per channel, posts to X, creates a LinkedIn organization post, and publishes to a Facebook Page—while logging results in PostgreSQL to prevent duplicates.

What this workflow does

• Runs on a 15-minute schedule to start an RSS cross-posting cycle.
• Validates configuration for RSS feed URLs, destination setup, and stops with an error summary if required values are missing or invalid.
• Ensures a PostgreSQL ledger exists to store publication outcomes and enforce idempotency.
• Reads and normalizes RSS items (title, excerpt, URL, publish date) from each enabled feed, with optional UTM parameter appending to links.
• Creates channel-specific publication candidates, generates a SHA-256 content hash, and routes candidates to X, LinkedIn, and/or Facebook based on enabled channels.
• Posts to X, creates a LinkedIn organization post, and publishes to a Facebook Page—skipping Facebook API calls in dry-run mode.
• Upserts a per-channel result record into PostgreSQL and generates a run summary with counts and warnings across all attempted publications.

Use cases

• SaaS operators sharing new blog posts or product updates across X, LinkedIn, and Facebook without manual posting.
• Automation engineers building an idempotent RSS publishing system for multiple feeds.
• Teams that need consistent, channel-specific messaging and traceable publishing history in PostgreSQL.
