Clean contact records: Slack & MySQL
Runs on a schedule across Slack, MySQL and Google Sheets, branches on the check before anything is written, then drops anything it has already handled. Built for multi-tool agent, around a "Fetch Changes Since Watermark" step, in 23 documented nodes.
Clean contact records with HubSpot and HTTP / REST API and log the results. 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 Slack, MySQL, 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. What used to take a morning now runs on its own.

- ✓A failed Slack or MySQL call is retried rather than dropped, at any of the 23 nodes in this multi-tool-agent build
- ✓Fans the same result out to Google Sheets in the same run, for multi-tool agent
- ✓Pinned sample data ships with it — run all 23 nodes for multi-tool agent before wiring Slack
Use cases

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
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 (Slack, MySQL, Google Sheets, 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.
