How it works

This workflow automates LinkedIn community engagement by monitoring post comments, filtering new ones, generating AI-powered replies, and posting responses directly on LinkedIn. It also logs all interactions into Google Sheets for tracking and analytics.

Step-by-step

Trigger & Fetch

  • A Schedule Trigger runs the workflow every 10 minutes.

  • The workflow fetches the latest comments on a specific LinkedIn post using LinkedIn’s API with token-based authentication.

Filter for New Comments

  • Retrieves the timestamp of the last processed comment from Google Sheets.

  • Filters out previously handled comments, ensuring only fresh interactions are processed.

AI-Powered Reply Generation

  • Sends the new comment to OpenAI GPT-3.5 Turbo with a structured prompt.

  • AI generates a professional, concise, and engaging LinkedIn-appropriate reply (max 2–3 sentences).

Post Back to LinkedIn

  • Automatically posts the AI-generated reply under the original comment thread.

  • Maintains consistent formatting and actor identity.

Data Logging

  • Appends the original comment, AI response, and metadata into Google Sheets.

  • Enables tracking, review, and future engagement analysis.

Benefits

  • Saves time by automating LinkedIn comment replies.

  • Ensures responses are timely, professional, and on-brand.

  • Maintains authentic engagement without manual effort.

  • Prevents duplicate replies by filtering with timestamps.

  • Creates a structured log in Google Sheets for auditing and analytics.
