🎥 YouTube to LinkedIn Poster – n8n Workflow Template

Turn any YouTube video into a high-performing LinkedIn post — automatically.

This AI-powered n8n workflow takes a YouTube video ID, fetches the transcript using SearchAPI.io, and transforms it into a professional, engaging LinkedIn post using OpenAI (via OpenRouter). Customize the writing style, automate your content repurposing, and scale your thought leadership.

⚡ What It Does

• 📄 Retrieves transcript via SearchAPI.io

• 🧠 Uses LLM (OpenRouter / GPT-compatible) to generate a polished LinkedIn post

• ✍️ Supports writing style customization (e.g., educational, inspirational, storytelling)

• 🔁 Handles fallback if no transcript is found

📦 What’s Included

• ✅ Webhook-based trigger (compatible with any frontend)

• ✅ YouTube transcript fetcher using SearchAPI.io

• ✅ Conditional logic to handle errors

• ✅ OpenAI content generation node with injected personality prompt

• ✅ Clean text response via webhook

🛠 Requirements

• 🧠 n8n (self-hosted or cloud)

• 🔐 API key for SearchAPI.io

• 🧠 OpenRouter API key (free or paid)

• 🌐 A frontend form (e.g. WordPress + fetch(), Fillout, Postman, etc.)

🚀 Installation Guide

1. Import the Workflow

   • Go to your n8n dashboard

   • Click Import and upload the JSON file

2. Configure SearchAPI

   • Sign up at SearchAPI.io

   • Add your API key inside the HTTP Request node labeled Get YouTube Transcript

3. Set Up OpenRouter

   • Go to Credentials → Add a new OpenRouter API credential

   • Paste your API key from OpenRouter.ai

4. Test with Postman or UI

   • Send a POST to the webhook URL with JSON:

     
     {
     
       "video_id": "T1nX2yDeSzM",
     
       "llm_profile": "educational tone"
     
     }
     
     

🧩 Customizing

• 🎨 Change llm_profile to match different tones (e.g., "inspirational", "founder voice", "storyteller")

• 🔗 Integrate output directly into LinkedIn via a social media scheduler API

• ✏️ Edit the prompt in the OpenAI node for different content types (Twitter threads, blog intros)

• 🚨 Add rate limiting or credit logic using WordPress + myCred or n8n queue control

💡 Use Cases

• Content repurposing agency automating short-form content from videos

• Personal brand managers scaling 1 → many posts from long-form video

• Micro-SaaS founders turning webinars, tutorials, and walkthroughs into professional posts

• YouTube creators expanding audience reach on LinkedIn

🚀 How I Used It in My MicroSaaS

I used this exact workflow as the backend for a lead magnet SaaS tool that converts YouTube videos into LinkedIn posts. With a simple UI and webhook, users paste a video link, choose a tone, and instantly receive a high-quality post they can copy and share. It increased lead generation and engagement while costing nothing in backend dev. Check it out here: Youtube -> LinkedIn Post

The best part? I only used:

• n8n + Webhook

• SearchAPI.io

• OpenRouter API

• A WordPress front-end with credit gating
