Clean contact records: Slack + sub-workflow
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 capture forms, around a "Keep Valid Leads" step, in 31 documented nodes.
Clean contact records with HubSpot and HTTP / REST API without manual work for Capture Forms. An original, ready-to-import n8n workflow built around the 'Data Enrichment' pattern for sales & CRM. It runs on a schedule and orchestrates 31 nodes across Slack, HTTP / REST API, Google Sheets. 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 Slack and Google Sheets in step for capture forms, without anyone re-typing a row
- ✓Safe to re-run: records already in Slack or Google Sheets are skipped, across all 31 nodes of this capture-forms build
- ✓A failed Slack or Google Sheets call is retried rather than dropped, at any of the 31 nodes in this capture-forms build
- ✓Branches rejoin before Slack, so a capture-forms run reports once rather than 31 times
- ✓Every capture-forms run leaves an audit row behind, alongside Slack
Use cases
- →Teams keeping Slack and Google Sheets aligned by hand for capture forms
- →Capture forms work where "Keep Valid Leads" is still a manual step before Slack
- →Capture forms work that only reaches Slack 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.

What you'll learn
Architect levelThe deepest tier - sub-workflow delegation, state snapshots, and full observability.
- •Building a provider waterfall that only pays for a fallback on a real miss
- •Scoring records after enrichment so the score sees the richest data
- •Upserting so repeat runs update rather than duplicate
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, HTTP / REST API, Google Sheets, Notion, …). 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.
