How to notify Slack when a HubSpot deal over $50K is created

Why alert on large deals?

When a $50K+ deal enters the pipeline, leadership wants to know immediately — but in most orgs, they don't find out until the weekly pipeline review. By then, the deal has been sitting for 3-5 days without executive support, custom pricing, or the attention that large deals need to close.

The cost of delayed visibility is real. Large deals often require cross-functional coordination: legal for contract review, finance for custom pricing, executives for relationship-building. Every day of delay is a day the prospect might be talking to a competitor who moves faster. Research from Gartner shows that deals with executive involvement close at 2x the rate — but only if executives get involved early.

An automated Slack alert solves this by notifying leadership the moment a large deal is created, with full context: deal name, amount, owner, and a direct link to the HubSpot record.

How it works

Regardless of which tool you use, every approach follows the same three-step pattern:

1. Detect the deal — monitor HubSpot for newly created deals. Some tools use webhooks for instant detection, others poll the API on a schedule.
2. Check the amount — compare the deal's amount property against your threshold (e.g., $50,000). Deals below the threshold are silently ignored.
3. Alert leadership — post a formatted message to a Slack channel with the deal name, amount, owner, and a link so anyone can click through to the full HubSpot record.

The approaches below differ in how they detect new deals — some give you real-time delivery via webhooks, some poll every few minutes, and some run on-demand. Pick the one that fits your team.

What you'll need

Which approach should I use?

• Zapier (Recommended) — fastest setup, zero code, built-in HubSpot trigger. Best for non-technical teams who want alerts running in under 10 minutes. Per-task pricing means you pay for each deal created, but filtered deals don't count.
• n8n — visual workflow editor, self-hostable for free, webhook-based for near-instant delivery. Best for teams with a technical ops person who wants full control and no per-task fees.
• Make — visual builder with lower pricing than Zapier, polling-based. Best for teams already using Make or who want a middle ground between cost and ease.
• Code + Cron — HubSpot webhook subscription + Express handler. Best for engineering teams who want real-time alerts with zero ongoing cost and full customization.
• Claude Code — a guided Claude Code skill with workflow guidelines and API references. Ask Claude to find large deals and post alerts conversationally. Best for periodic checks and ad hoc queries like "what deals over $100K were created this week?"
