Mirror contacts across systems for utilities

Runs on a schedule across Google Sheets, MySQL and Slack, branches on the check before anything is written, then drops anything it has already handled. Built for utilities, around a "Fetch Changes Since Watermark" step, in 23 documented nodes.

Mirror contacts across systems with HubSpot and MySQL end to end. An original, ready-to-import n8n workflow built around the 'Two-System Sync' pattern for productivity & personal. It runs on a schedule and orchestrates 23 nodes across Google Sheets, MySQL, Slack. 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 MySQL in step for utilities, without anyone re-typing a row
  • Safe to re-run: records already in Google Sheets or MySQL are skipped, across all 23 nodes of this utilities build
  • A failed Google Sheets or MySQL call is retried rather than dropped, at any of the 23 nodes in this utilities build
  • Fans the same result out to Slack in the same run, for utilities
  • Pinned sample data ships with it — run all 23 nodes for utilities before wiring Google Sheets

Use cases

  • Teams keeping Google Sheets and MySQL aligned by hand for utilities
  • Utilities work where "Fetch Changes Since Watermark" is still a manual step before Google Sheets
  • Utilities 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.

  • Choosing a stable matching key for reconciliation
  • Making a sync safe to re-run without creating duplicates
  • Moving data between MySQL, Google Sheets and Twilio in a single run

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, MySQL, 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.
