AI-Generated LinkedIn Posts with Human Approval using GPT-4, GoToHuman & Blotato

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

📅 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.

🧠 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.

👤 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.

🚀 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
