HubSpot to Slack Notifications Workflow Automation

Our sales team lives in HubSpot, but nobody sees deal updates unless they happen to be logged in and looking at the right pipeline. By the time someone notices a deal moved to "Closed Won" or got stuck in a stage for too long, we've already lost the moment to act on it. I want an n8n workflow that watches for specific HubSpot deal events (new deal created, stage change, deal closed) and posts a formatted message into the right Slack channel the moment it happens. Different event types should probably route to different channels, happy to discuss the best setup with whoever takes this on. This needs to be reliable since we'll depend on it daily. If HubSpot or Slack has an outage, the workflow should recover gracefully rather than silently dropping notifications. HubSpot and Slack are both already active in our business, so this is purely the automation layer between them. Someone with hands-on n8n and HubSpot API experience will get this done fastest. Please mention if you've built HubSpot-triggered workflows before.
