Sync contacts across systems: PostgreSQL
Runs on a schedule across PostgreSQL and HubSpot, diffs the two sides and writes only the gaps, then rolls the rows up into a few numbers. Built for integrations, around a "Pull Side A (HubSpot)" step, in 9 documented nodes.
Sync contacts across systems with HubSpot and PostgreSQL on autopilot. An original, ready-to-import n8n workflow built around the 'Two-System Sync' pattern for productivity & personal. It runs on a schedule and orchestrates 9 nodes across PostgreSQL, HubSpot. 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 PostgreSQL and HubSpot in step for integrations, without anyone re-typing a row
- ✓Compares PostgreSQL against HubSpot before writing, so only genuine differences land
- ✓A failed PostgreSQL or HubSpot call is retried rather than dropped, at any of the 9 nodes in this integrations build
- ✓Pinned sample data ships with it — run all 9 nodes for integrations before wiring PostgreSQL
- ✓9 nodes, each with a doc card explaining what it does for integrations
Use cases
- →Teams keeping PostgreSQL and HubSpot aligned by hand for integrations
- →Reconciling PostgreSQL against HubSpot after the two quietly drifted apart
- →Integrations work where "Pull Side A (HubSpot)" is still a manual step before PostgreSQL
- →Integrations work that only reaches PostgreSQL on a schedule, when someone remembers to start it
Integrations
Workflow preview (9 nodes)
The template's actual node layout and connections. Node parameters and credential slots unlock with the download.
What's inside (9 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
Foundation levelA starter-sized build - small enough to hold in your head while you learn the pattern.
- •Diffing two datasets into add / update / in-sync / backfill lanes
- •Choosing a stable matching key for reconciliation
- •Moving data between HubSpot and PostgreSQL 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 (PostgreSQL, HubSpot). 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.
