Mirror contacts across systems: MySQL
Runs on a schedule across MySQL, HubSpot and Google Sheets, diffs the two sides and writes only the gaps, then drops anything it has already handled. Built for triggers, around a "Pull Side A (HubSpot)" step, in 23 documented nodes.
Mirror contacts across systems with HubSpot and MySQL hands-free. 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 MySQL, HubSpot, Google Sheets. Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. Nothing slips through the cracks.
Key benefits
- ✓Keeps MySQL and HubSpot in step for triggers, without anyone re-typing a row
- ✓Compares MySQL against HubSpot before writing, so only genuine differences land
- ✓Safe to re-run: records already in MySQL or HubSpot are skipped, across all 23 nodes of this triggers build
- ✓A failed MySQL or HubSpot call is retried rather than dropped, at any of the 23 nodes in this triggers build
- ✓Every triggers run leaves an audit row behind, alongside MySQL
Use cases
- →Teams keeping MySQL and HubSpot aligned by hand for triggers
- →Reconciling MySQL against HubSpot after the two quietly drifted apart
- →Triggers work where "Pull Side A (HubSpot)" is still a manual step before MySQL
- →Triggers work that only reaches MySQL on a schedule, when someone remembers to start it

What's inside (23 nodes)
A look at the node types this workflow uses. No purchase required — full parameters and credentials are yours after you buy.
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
Production levelProduction-grade: idempotency, dead-letter handling, and reconciliation included.
- •Diffing two datasets into add / update / in-sync / backfill lanes
- •Choosing a stable matching key for reconciliation
- •Making a sync safe to re-run without creating duplicates
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 (MySQL, HubSpot, Google Sheets, Slack, …). 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.
