Alert on stock levels: Google Sheets & Twilio

Runs on a schedule across Google Sheets, Twilio and Slack, diffs the two sides and writes only the gaps, then scrapes the values straight out of the HTML. Built for digests, around a "Fetch Target Page" step, in 22 documented nodes.

Alert on stock levels with HTTP / REST API and Twilio and log the results. An original, ready-to-import n8n workflow built around the 'Threshold Monitoring' pattern for software development & devops. It runs on a schedule and orchestrates 22 nodes across Google Sheets, Twilio, Slack. Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. Your team sees the right data at the right time.

Key benefits

  • Keeps Google Sheets and Twilio in step for digests, without anyone re-typing a row
  • Compares Google Sheets against Twilio before writing, so only genuine differences land
  • Safe to re-run: records already in Google Sheets or Twilio are skipped, across all 22 nodes of this digests build
  • A failed Google Sheets or Twilio call is retried rather than dropped, at any of the 22 nodes in this digests build
  • Every digests run leaves an audit row behind, alongside Google Sheets

Use cases

  • Teams keeping Google Sheets and Twilio aligned by hand for digests
  • Reconciling Google Sheets against Twilio after the two quietly drifted apart
  • Digests work where "Fetch Target Page" is still a manual step before Google Sheets
  • Digests work that only reaches Google Sheets on a schedule, when someone remembers to start it

From download to running in 3 steps

  1. 1
    Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.
  2. 2
    Connect. Add your own credentials on the app nodes - n8n highlights exactly which ones need them.
  3. 3
    Activate. Run it once to test, then toggle Active. The automation is live.

What you'll learn

Production level

Production-grade: idempotency, dead-letter handling, and reconciliation included.

  • Suppressing repeat alerts so one incident pages once
  • Moving data between Google Sheets, Slack and Twilio in a single run
  • Normalising timestamps before anything downstream compares them

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, Twilio, Slack, HTTP / REST API). 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.
