Mirror records between tools with Slack
Runs on a schedule across Slack, Google Sheets and Notion, branches on the check before anything is written, then drops anything it has already handled. Built for enrichment, around a "Fetch Changes Since Watermark" step, in 32 documented nodes.
Mirror records between tools with HubSpot and PostgreSQL 24/7. An original, ready-to-import n8n workflow built around the 'Two-System Sync' pattern for sales & CRM. It runs on a schedule and orchestrates 32 nodes across Slack, Google Sheets, HTTP / REST API. 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 Slack and Google Sheets in step for enrichment, without anyone re-typing a row
- ✓Safe to re-run: records already in Slack or Google Sheets are skipped, across all 32 nodes of this enrichment build
- ✓A failed Slack or Google Sheets call is retried rather than dropped, at any of the 32 nodes in this enrichment build
- ✓Every enrichment run leaves an audit row behind, alongside Slack
- ✓Fans the same result out to Notion in the same run, for enrichment
Use cases
- →Teams keeping Slack and Google Sheets aligned by hand for enrichment
- →Enrichment work where "Fetch Changes Since Watermark" is still a manual step before Slack
- →Enrichment work that only reaches Slack on a schedule, when someone remembers to start it

What you'll learn
Architect levelThe deepest tier - sub-workflow delegation, state snapshots, and full observability.
- •Choosing a stable matching key for reconciliation
- •Making a sync safe to re-run without creating duplicates
- •Moving data between Notion, Google Sheets 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 (Slack, Google Sheets, HTTP / REST API, Notion, …). 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.
