Replicate contacts across systems: HubSpot & PostgreSQL
Runs on a schedule across HubSpot, PostgreSQL and Slack, routes each kind of record down its own branch, then drops anything it has already handled. Built for follow-ups, around a "Map to Canonical Schema" step, in 24 documented nodes.
Replicate contacts across systems with HubSpot and PostgreSQL in real time. An original, ready-to-import n8n workflow built around the 'Two-System Sync' pattern for sales & CRM. It runs on a schedule and orchestrates 24 nodes across HubSpot, PostgreSQL, Slack. 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 HubSpot and PostgreSQL in step for follow-ups, without anyone re-typing a row
- ✓Safe to re-run: records already in HubSpot or PostgreSQL are skipped, across all 24 nodes of this follow-ups build
- ✓A failed HubSpot or PostgreSQL call is retried rather than dropped, at any of the 24 nodes in this follow-ups build
- ✓Branches rejoin before HubSpot, so a follow-ups run reports once rather than 24 times
- ✓Every follow-ups run leaves an audit row behind, alongside HubSpot
Use cases
- →Teams keeping HubSpot and PostgreSQL aligned by hand for follow-ups
- →Follow-ups work where "Map to Canonical Schema" is still a manual step before HubSpot
- →Follow-ups work that only reaches HubSpot on a schedule, when someone remembers to start it
Integrations
Workflow preview (24 nodes)
The template's actual node layout and connections. Node parameters and credential slots unlock with the download.
What's inside (24 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.
- •Choosing a stable matching key for reconciliation
- •Making a sync safe to re-run without creating duplicates
- •Moving data between PostgreSQL, 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 (HubSpot, PostgreSQL, 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.
