This n8n workflow automates the process of generating, reviewing, and posting LinkedIn captions based on daily ideas stored in Google Sheets. It integrates multiple services including OpenAI for caption generation, GoToHuman for human approval, and Blotato for publishing posts.

The workflow begins with a scheduled trigger or manual start, where it retrieves today’s idea from Google Sheets using the current date. This idea is then sent to OpenAI’s GPT model to generate an engaging LinkedIn caption enriched with emojis. Next, the caption is forwarded to GoToHuman, allowing a human reviewer to approve or reject the content. If approved, the caption is sent via an HTTP request to Blotato to be posted on LinkedIn.

Throughout the process, notes and instructions are included to guide setup and provide context for each step. The workflow ensures a streamlined, semi-automated approach to content creation, review, and posting, ideal for social media marketing teams aiming for consistent and engaging LinkedIn updates without manual intervention at every step.
