Alert on stock levels: Google Sheets, Slack & Telegram
Runs on a schedule across Google Sheets, Slack and Telegram, diffs the two sides and writes only the gaps, then scrapes the values straight out of the HTML. Built for real-time alerts, around a "Fetch Target Page" step, in 14 documented nodes.
Alert on stock levels with HTTP / REST API and Telegram hands-free. An original, ready-to-import n8n workflow built around the 'Threshold Monitoring' pattern for software development & devops. It runs on a schedule and orchestrates 14 nodes across Google Sheets, Slack, HTTP / REST API. Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. What used to take a morning now runs on its own.
Key benefits
- ✓Keeps Google Sheets and Slack in step for real-time alerts, without anyone re-typing a row
- ✓Compares Google Sheets against Slack before writing, so only genuine differences land
- ✓A failed Google Sheets or Slack call is retried rather than dropped, at any of the 14 nodes in this real-time-alerts build
- ✓Every real-time-alerts run leaves an audit row behind, alongside Google Sheets
- ✓Fans the same result out to Telegram in the same run, for real-time alerts
Use cases
- →Teams keeping Google Sheets and Slack aligned by hand for real-time alerts
- →Reconciling Google Sheets against Slack after the two quietly drifted apart
- →Real-time alerts work where "Fetch Target Page" is still a manual step before Google Sheets
- →Real-time alerts work that only reaches Google Sheets on a schedule, when someone remembers to start it

From download to running in 3 steps
- 1Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
- 2Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
- 3Activate. Run it once to test, then toggle Active. The automation is live.
What you'll learn
Core levelA compact production shape: validation and error handling without extra machinery.
- •Moving data between Google Sheets, Slack and Telegram in a single run
- •Adding retries and an explicit error path to external calls
- •Testing against pinned sample data before connecting anything real
Every node carries its own documentation on the canvas, plus notes explaining why the architecture was built this way, a credential setup guide, troubleshooting, and three practice exercises. Sample data comes pinned to the trigger, so you can hit Execute and watch data flow before connecting a single account.
Common questions
What exactly do I get?
The complete, ready-to-import n8n workflow as a JSON file, delivered instantly after payment. Import it into your own n8n (cloud or self-hosted), add your credentials, and it runs.
How do I import it into n8n?
In n8n, open Workflows, click the three-dot menu, choose “Import from File”, and select the downloaded JSON. Then connect your own app credentials on the highlighted nodes.
Do I need anything else for it to work?
You need your own n8n instance and accounts/credentials for the apps this workflow connects to (Google Sheets, Slack, HTTP / REST API, Telegram). No coding is required.
What if it doesn't work for me?
If the file is faulty, won't import, or isn't as described, contact us within 7 days and we'll fix it or refund you - see our refund policy.
Can I modify or resell it?
You can freely adapt and use it in your own or your clients' projects. Reselling or redistributing the template file itself is not permitted.
