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

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.
