Sync contacts across systems: MySQL
Runs on a schedule across MySQL, Slack and HubSpot, branches on the check before anything is written, then drops anything it has already handled. Built for contact sync, around a "Fetch Changes Since Watermark" step, in 23 documented nodes.
Sync contacts across systems with HubSpot and MySQL and log the results. An original, ready-to-import n8n workflow built around the 'Two-System Sync' pattern for sales & CRM. It runs on a schedule and orchestrates 23 nodes across MySQL, Slack, HTTP / REST API. Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. The result is a hands-off process that just works.
Key benefits
- ✓Keeps MySQL and Slack in step for contact sync, without anyone re-typing a row
- ✓Safe to re-run: records already in MySQL or Slack are skipped, across all 23 nodes of this contact-sync build
- ✓A failed MySQL or Slack call is retried rather than dropped, at any of the 23 nodes in this contact-sync build
- ✓Fans the same result out to HubSpot in the same run, for contact sync
- ✓Pinned sample data ships with it — run all 23 nodes for contact sync before wiring MySQL
Use cases
- →Teams keeping MySQL and Slack aligned by hand for contact sync
- →Contact sync work where "Fetch Changes Since Watermark" is still a manual step before MySQL
- →Contact sync work that only reaches MySQL on a schedule, when someone remembers to start it

What you'll learn
Production levelProduction-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, HubSpot and Slack 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 (MySQL, Slack, HTTP / REST API, HubSpot, …). No coding is required.

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.
