What it does
This workflow is designed for creators, marketers, and agencies who want to automate content publishing while keeping quality control through human review. It integrates four powerful tools — Google Sheets, OpenAI, GoToHuman, and Blotato — to deliver a seamless AI-assisted, human-approved, auto-publishing system for LinkedIn. --- ⚙️ What This Workflow Does 1. 📅 Pulls Today’s Topic from Google Sheets - You store ideas in a spreadsheet with a date column. - The workflow runs daily (or manually) and selects the row matching today’s date. 2. 🧠 Generates a Caption with OpenAI - The selected idea is passed to GPT-4 via an AI Agent node. - OpenAI returns a short, emoji-rich LinkedIn caption (1–2 sentences). - The result is saved back to the sheet. 3. 👤 Sends the Caption for Human Review via GoToHuman - A human reviewer sees the AI-generated caption. - They approve or reject it using a GoToHuman review template. - Only approved captions move forward. 4. 🚀 Publishes the Approved Caption to LinkedIn via Blotato - The caption is posted to a LinkedIn account via Blotato's API. - No additional input is required — it's fully automated after approval. --- 🔧 Setup Requirements ✅ Google Sheets - Create or copy the provided sample sheet. - Connect your Google Sheets account in n8n using OAuth2. ✅ OpenAI - Create an API key at platform.openai.com. - Add it to n8n as an OpenAI credential. ✅ GoToHuman - Create an account and a Review Template at gotohuman.com. - Add your API credential in n8n and use your reviewTemplateId in the node. ✅ Blotato - Create an account at blotato.com. - Get your API key and Account ID. - Insert them into the HTTP Request node that publishes the LinkedIn post. --- 🧪 Testing the Workflow - Use the Manual Trigger node for step-by-step debugging. - Review nodes like AI Agent, Ask Human for Approval, and Post to LinkedIn to verify output. - Once confirmed, activate the schedule for fully hands-free publishing. --- 👋 Built By Robert Breen Founder of Ynteractive — Automation, AI, and Data Strategy 🌐 Website: https://ynteractive.com 📧 Email: [email protected](mailto:[email protected]) 🔗 LinkedIn: https://www.linkedin.com/in/robert-breen-29429625/ 📺 YouTube: YnteractiveTraining --- 🏷 Tags linkedin openai gotohuman social automation ai content approval workflow google sheets blotato marketing automation
