Notify Slack when a HubSpot deal over $50K is created using n8n

Prerequisites

Step 1: Add HubSpot Trigger

Add a HubSpot Trigger node:

• Event: Deal Created

This fires for every new deal. You'll filter by amount in the next step.

Step 2: Fetch deal details

Add an HTTP Request node:

• Method: GET
• URL: https://api.hubapi.com/crm/v3/objects/deals/{{ $json.objectId }}
• Authentication: HubSpot credential
• Query params: properties=dealname,amount,dealstage,hubspot_owner_id,pipeline

Step 3: Filter by amount

Add an IF node:

• Condition: {{ parseFloat($json.properties.amount || '0') }} greater than 50000

Only deals over $50K proceed to the Slack step.

Step 4: Resolve owner name

Add an HTTP Request to get the owner's name:

• URL: https://api.hubapi.com/crm/v3/owners/{{ $json.properties.hubspot_owner_id }}

Step 5: Send Slack alert

Add a Slack node:

• Channel: #executive-deals or #sales-leadership
• Message Type: Block Kit

{
  "blocks": [
    {
      "type": "section",
      "text": {
        "type": "mrkdwn",
        "text": "🎯 *New Large Deal Created*\n*{{ $('Fetch Deal').first().json.properties.dealname }}*\nAmount: *${{ parseFloat($('Fetch Deal').first().json.properties.amount).toLocaleString() }}*\nOwner: {{ $('Fetch Owner').first().json.firstName }} {{ $('Fetch Owner').first().json.lastName }}"
      }
    },
    {
      "type": "context",
      "elements": [
        {
          "type": "mrkdwn",
          "text": "<https://app.hubspot.com/contacts/YOUR_PORTAL_ID/deal/{{ $('Fetch Deal').first().json.id }}|View in HubSpot>"
        }
      ]
    }
  ]
}

Step 6: Activate

1. Test by creating a deal over $50K in HubSpot
2. Verify the Slack alert
3. Toggle to Active

Cost

• n8n Cloud: Only counts as 1 execution when a deal is created and passes the filter. Deals under $50K stop at the IF node but still count as 1 execution.
