Identify website visitors with Clearbit Reveal and create HubSpot companies using n8n

Prerequisites

n8n instance (cloud or self-hosted)
Clearbit Reveal API key (legacy) or HubSpot account with Breeze Intelligence add-on
HubSpot private app token with crm.objects.companies.read and crm.objects.companies.write scopes
A way to capture visitor IP addresses (server logs, analytics webhook, or middleware)
n8n credential configured for HubSpot

Clearbit is now Breeze Intelligence

Clearbit was acquired by HubSpot and rebranded as Breeze Intelligence. The standalone Reveal API is being sunset. If you're a new user, skip the legacy API approach and use Breeze Intelligence natively within HubSpot (see the Breeze alternative at the end). This guide covers both approaches.

Step 1: Set up a webhook to receive visitor IPs

Create a new workflow and add a Webhook node:

HTTP Method: POST
Path: /visitor-identify
Response Mode: Immediately

Your website or analytics platform will POST visitor data to this webhook. The payload should include at minimum:

{
  "ip": "203.0.113.42",
  "page": "/pricing",
  "timestamp": "2026-03-02T10:30:00Z"
}

Capturing IP addresses

Most analytics tools don't expose raw IPs. Common approaches: (1) server-side middleware that logs IPs and forwards to the webhook, (2) a Cloudflare Worker or Vercel Edge Function that captures CF-Connecting-IP or x-forwarded-for, (3) a GTM server-side container.

Step 2: Call Clearbit Reveal API

Add an HTTP Request node:

Method: GET
URL: https://reveal.clearbit.com/v1/companies/find?ip={{ $json.ip }}
Authentication: Header Auth
Header Name: Authorization
Header Value: Bearer YOUR_CLEARBIT_API_KEY

The response includes company name, domain, industry, employee count, and more.

Step 3: Filter for ICP matches

Add an IF node to filter out noise — ISPs, universities, and companies outside your target market:

Condition 1: $json.company.type equals company (filters out ISPs and education)
Condition 2: $json.company.metrics.employees greater than 50 (adjust for your ICP)
Condition 3: $json.company.category.sector is one of your target sectors

Most IPs won't resolve

Clearbit Reveal resolves roughly 20-30% of B2B traffic to a company. Consumer ISPs, VPNs, and mobile networks return null. Build your workflow to handle null responses gracefully.

Step 4: Check for existing companies in HubSpot

Add an HTTP Request node to search HubSpot by domain:

Method: POST
URL: https://api.hubapi.com/crm/v3/objects/companies/search
Body:

{
  "filterGroups": [{
    "filters": [{
      "propertyName": "domain",
      "operator": "EQ",
      "value": "{{ $json.company.domain }}"
    }]
  }]
}

Add an IF node: if total equals 0, create a new company. Otherwise, optionally update the existing record with the latest visit data.

Step 5: Create company in HubSpot

Add an HTTP Request node:

Method: POST
URL: https://api.hubapi.com/crm/v3/objects/companies
Body:

{
  "properties": {
    "domain": "{{ $json.company.domain }}",
    "name": "{{ $json.company.name }}",
    "industry": "{{ $json.company.category.industry }}",
    "numberofemployees": "{{ $json.company.metrics.employees }}",
    "city": "{{ $json.company.geo.city }}",
    "state": "{{ $json.company.geo.state }}",
    "country": "{{ $json.company.geo.country }}",
    "description": "{{ $json.company.description }}",
    "website_visitor_page": "{{ $('Webhook').item.json.page }}",
    "website_visitor_date": "{{ $('Webhook').item.json.timestamp }}"
  }
}

Step 6: Activate and test

Send a test POST to your webhook URL with a known corporate IP
Verify the company record appears in HubSpot with correct data
Toggle the workflow to Active

Breeze Intelligence alternative

If you're using HubSpot's Breeze Intelligence instead of the legacy Clearbit API, the visitor identification happens natively within HubSpot. No external API call is needed.

Setup in HubSpot:

Enable Breeze Intelligence in Settings → Breeze Intelligence
Install the HubSpot tracking code on your website
Breeze automatically identifies visiting companies and creates/updates records

You can then use an n8n workflow that triggers on new HubSpot companies (created by Breeze) to enrich or route them — for example, assigning them to a sales rep or posting a notification to Slack.

Cost

n8n Cloud Starter: $24/mo for 2,500 executions. Each visitor IP = 1 execution.
Self-hosted n8n: Free.
Clearbit Reveal (legacy): Pricing varies. Typically volume-based, starting around $99/mo for 2,500 API calls.
Breeze Intelligence: Included with HubSpot Marketing Hub or Sales Hub Professional+. Priced per credit — check your HubSpot contract for details.
