Clean contact records: 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 task automation, around a "Pull Side A (HubSpot)" step, in 23 documented nodes.
Clean contact records with HubSpot and HTTP / REST API without manual work for Task Automation. An original, ready-to-import n8n workflow built around the 'Data Enrichment' pattern for AI & automation. It runs on a schedule and orchestrates 23 nodes across PostgreSQL, HubSpot, Slack. It uses n8n's LangChain AI nodes (Agent/Chain + chat model). 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 task automation, 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 task-automation build
- ✓A failed PostgreSQL or HubSpot call is retried rather than dropped, at any of the 23 nodes in this task-automation build
- ✓Fans the same result out to Slack in the same run, for task automation
Use cases
- →Teams keeping PostgreSQL and HubSpot aligned by hand for task automation
- →Reconciling PostgreSQL against HubSpot after the two quietly drifted apart
- →Task automation work where "Pull Side A (HubSpot)" is still a manual step before PostgreSQL
- →Task automation work that only reaches PostgreSQL on a schedule, when someone remembers to start it

From download to running in 3 steps
- 1Import. In n8n, open Workflows → menu → “Import from File” and pick the downloaded JSON.

- 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.
- •Scoring records after enrichment so the score sees the richest data
- •Upserting so repeat runs update rather than duplicate
- •Moving data between HubSpot, PostgreSQL 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 (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.
