Clean contact records with HubSpot and MySQL
Runs on a schedule across HubSpot, MySQL and Slack, diffs the two sides and writes only the gaps, then drops anything it has already handled. Built for multi-tool agent, around a "Pull Side A (HubSpot)" step, in 31 documented nodes.
Clean contact records with HubSpot and HTTP / REST API for Multi-Tool Agent . An original, ready-to-import n8n workflow built around the 'Data Enrichment' pattern for AI & automation. It runs on a schedule and orchestrates 31 nodes across HubSpot, MySQL, 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. What used to take a morning now runs on its own.
Key benefits
- ✓Keeps HubSpot and MySQL in step for multi-tool agent, without anyone re-typing a row
- ✓Compares HubSpot against MySQL before writing, so only genuine differences land
- ✓Safe to re-run: records already in HubSpot or MySQL are skipped, across all 31 nodes of this multi-tool-agent build
- ✓A failed HubSpot or MySQL call is retried rather than dropped, at any of the 31 nodes in this multi-tool-agent build
- ✓Every multi-tool-agent run leaves an audit row behind, alongside HubSpot
Use cases
- →Teams keeping HubSpot and MySQL aligned by hand for multi-tool agent

What you'll learn
Architect levelThe deepest tier - sub-workflow delegation, state snapshots, and full observability.
- •Scoring records after enrichment so the score sees the richest data
- •Upserting so repeat runs update rather than duplicate
- •Moving data between HubSpot, MySQL and Google Sheets 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 (HubSpot, MySQL, Slack, Google Sheets, …). 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.
