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

✅ 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.
