Every morning the Schedule Trigger starts the workflow.\n2. The **Settings** node holds your places (Google Maps links, place IDs or \"business name, city\") and the highest star rating to alert on.\n3. The **Google Maps Reviews Scraper** Actor on Apify (`plainrows/google-maps-reviews`) runs with **Only new reviews** on: it remembers the reviews it already delivered, so each run returns only reviews posted since the last one.\n4. A Code node keeps the new reviews at or under your rating, groups them by place and builds one message with stars, text, date and a link to each review.\n5. The message is posted to Slack. No new low rating, no message.\n\n### Requirements\n- An Apify account (free plan available) and its API token.\n- A Slack workspace and the Slack credential in n8n.\n- The Apify node is the verified community node `@apify/n8n-nodes-apify` (available on n8n Cloud; on self-hosted n8n install it from Settings > Community nodes).\n\n### How to customize\n- Edit `places` (one per line), `maxStars` and `monitorName` in **Settings**. Use a new `monitorName` to start a fresh history.\n- Set `maxStars` to 5 to get every new review, not only the bad ones.\n- Replace Slack with Gmail, Microsoft Teams or Google Sheets using the same fields.\n\nReviewer names are not collected. The first run reads the 20 newest reviews of each place and seeds the memory; later runs only pay for new reviews plus a small fee per block of 10 reviews checked.", "height": 760, "width": 520 }, "id": "7ce49124-a67f-5201-a055-24fd87a5ef31", "name": "Description", "type": "n8n-nodes-base.stickyNote", "typeVersion": 1, "position": [ -660, -340 ] }, { "parameters": { "content": "### Setup\n1.
