Mirror records between tools with PostgreSQL
Runs on a schedule across PostgreSQL, HubSpot and Slack, diffs the two sides and writes only the gaps, then drops anything it has already handled. Built for enrichment, around a "Pull Side A (HubSpot)" step, in 23 documented nodes.
Mirror records between tools 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 23 nodes across PostgreSQL, HubSpot, Slack. Retry-on-fail is enabled on external calls. Import the JSON, add your credentials, and adapt the parameters. Your team sees the right data at the right time.
Key benefits
- ✓Keeps PostgreSQL and HubSpot in step for enrichment, without anyone re-typing a row
- ✓Compares PostgreSQL against HubSpot before writing, so only genuine differences land
- ✓Safe to re-run: records already in PostgreSQL or HubSpot are skipped, across all 23 nodes of this enrichment build
- ✓A failed PostgreSQL or HubSpot call is retried rather than dropped, at any of the 23 nodes in this enrichment build
- ✓Every enrichment run leaves an audit row behind, alongside PostgreSQL
Use cases
- →Teams keeping PostgreSQL and HubSpot aligned by hand for enrichment
- →Reconciling PostgreSQL against HubSpot after the two quietly drifted apart
- →Enrichment work where "Pull Side A (HubSpot)" is still a manual step before PostgreSQL
- →Enrichment work that only reaches PostgreSQL on a schedule, when someone remembers to start it
Integrations

The template's actual node layout and connections. Node parameters and credential slots unlock with the download.
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 (PostgreSQL, HubSpot, 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.
