What it does
Quick overview This workflow runs every morning to find your Google Maps business listing with API Direct, fetch the newest reviews, and post new 1–3 star reviews to a Slack channel for fast team response. How it works 1. Runs every morning on a schedule. 2. Searches Google Maps via API Direct using a plain-text business query and keeps the top matching place. 3. Fetches the newest Google Maps reviews for that place via API Direct. 4. Deduplicates reviews by remembering previously seen review IDs in the workflow’s persistent static data. 5. Filters the remaining reviews to only those with a rating of 3 stars or lower. 6. Posts an alert to Slack with the rating, author, timestamp, review text snippet, whether the owner has replied, and a direct review link. Setup 1. Create an API Direct account, add your API Direct API key as n8n credentials, and select it in both API Direct nodes. 2. Connect a Slack account in n8n and select the destination channel for alerts. 3. Update the business search text (name and location) in the business settings so the workflow finds the correct Google Maps listing. 4. Activate the workflow so the “seen review” memory persists across scheduled runs.
