Social Media Automation System (Free Template)!!!

Stop there.....!

I just built a social media automation system that runs a Facebook page on complete autopilot & the workflow canvas looks like a city map.

Let me break down what's actually happening inside:

4 content sources. One brain. Zero manual work.

📡 RSS Feed — Pulls live news automatically, detects whether each item is text, image, or video, rewrites it with AI, generates a matching image if needed, and posts it. All by itself. 3 posts/day cap so the page doesn't spam.

🔗 Blog Post URL — Drop any URL. The system scrapes the full article, extracts the content, rewrites it into an engaging Facebook caption, generates a custom image, and publishes. You never even open Facebook.

🎬 YouTube Summary — Paste a YouTube link. It fetches the full transcript, summarizes the key points, turns it into a scroll-stopping post, generates a thumbnail-style graphic, and posts it with your custom link in the caption.

✍️ Manual PostFlow Form — Built a custom Lovable UI where the client selects post type, writes their content, picks an image style, and hits submit. n8n handles everything after that — AI rewrite, image gen, Facebook post. Instant or scheduled.

The tech stack running under the hood:

→ n8n for workflow orchestration (self-hosted on VPS) → OpenAI GPT-4o-mini for content rewriting and summarization → fal.ai Flux for AI image generation → Facebook Graph API for publishing → Google Sheets for scheduling, daily limits, deduplication, and error logging → Lovable for the front-end submission form

---

The hard problems I solved along the way:

🔴 Facebook deprecated publish_actions — had to ditch n8n's built-in node and rebuild with raw HTTP requests using the modern Graph API

🔴 Dynamic AI-generated text was breaking JSON bodies — solved with JSON.stringify() in a Code node before every HTTP request

🔴 RSS feeds sending 15+ items/day — built a daily post counter using Google Sheets date filtering so it caps at exactly 3 posts/day

🔴 Same RSS item firing multiple times — built a GUID-based deduplication check before every post attempt

🔴 Inconsistent RSS feed structure — built a smart parser that detects media:content, enclosure, and <img> tags inside HTML descriptions to correctly identify text vs image vs video

---

The workflow canvas has 100+ nodes across 4 workflows.

The client experience? They open their Facebook page and it's already posted. 📱

This is what automation looks like when you actually finish it — not just a demo, but a production system handling real content, real edge cases, and real failures gracefully.

If you're a business still manually writing and posting social media content every day — this is what you're leaving on the table.
