Enrich contact records: Google Sheets + approval pause
Runs on a schedule across Google Sheets, Slack and PostgreSQL, walks the list in batches, pausing between them, then branches on the check before anything is written. Built for research assistant, around a "Read Pending Queue (Google Sheets)" step, in 23 documented nodes.
Enrich contact records with Google Sheets and HTTP / REST API with instant alerts for Research Assistant. 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 Google Sheets, Slack, HTTP / REST API. 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. The result is a hands-off process that just works.
Key benefits
- ✓Keeps Google Sheets and Slack in step for research assistant, without anyone re-typing a row
- ✓Safe to re-run: records already in Google Sheets or Slack are skipped, across all 23 nodes of this research-assistant build
- ✓A failed Google Sheets or Slack call is retried rather than dropped, at any of the 23 nodes in this research-assistant build
- ✓Bad input stops the run for research assistant instead of landing in Google Sheets
- ✓The pause before Google Sheets is durable — a research-assistant run survives a restart
Use cases
- →Teams keeping Google Sheets and Slack aligned by hand for research assistant
- →Research assistant sequences that run over days and must survive a restart before Google Sheets
- →A backlog too large to push into Google Sheets in one pass, across 23 nodes
- →Research assistant work where "Read Pending Queue (Google Sheets)" is still a manual step before Google Sheets
Integrations
Workflow preview (23 nodes)
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.
- •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 (Google Sheets, Slack, HTTP / REST API, PostgreSQL). 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.
