• Landing Page Optimization: Measure performance of HubSpot landing pages
• Marketing Automation: Trigger workflows based on ad engagement
• Attribution: Understand the full customer journey from ad to customer

Installation Methods

Method 1: HubSpot Tracking Code (Recommended)

HubSpot provides a dedicated area for third-party tracking codes.

Installation Steps

1. Get Your Pixel ID

Navigate to Facebook Events Manager:

• Select your pixel
• Copy the Pixel ID (15-16 digit number)
• Copy the base pixel code

2. Access HubSpot Settings

In your HubSpot account:

• Navigate to Settings (gear icon)
• Select Tracking & Analytics > Tracking Code
• Or visit: https://app.hubspot.com/settings/[PORTAL_ID]/marketing/tracking/code

3. Add Pixel Code

Scroll to Footer HTML section and paste:

<!-- Meta Pixel Code -->
<script>
!function(f,b,e,v,n,t,s)
{if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};
if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];
s.parentNode.insertBefore(t,s)}(window, document,'script',
'https://connect.facebook.net/en_US/fbevents.js');
fbq('init', 'YOUR_PIXEL_ID');
fbq('track', 'PageView');
</script>
<noscript>
  <img height="1" width="1" style="display:none"
    src="https://www.facebook.com/tr?id=YOUR_PIXEL_ID&ev=PageView&noscript=1"/>
</noscript>
<!-- End Meta Pixel Code -->

4. Publish Changes

Click Save to apply across all HubSpot-hosted pages.

Advantages

• Automatically applies to all HubSpot pages and landing pages

In Google Tag Manager:

• Tags > New
• Tag Type: Custom HTML
• Tag Name: "Meta Pixel - Base Code"

<script>
!function(f,b,e,v,n,t,s)
{if(f.fbq)return;n=f.fbq=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};
if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
n.queue=[];t=b.createElement(e);t.async=!0;
t.src=v;s=b.getElementsByTagName(e)[0];
s.parentNode.insertBefore(t,s)}(window, document,'script',
'https://connect.facebook.net/en_US/fbevents.js');
fbq('init', 'YOUR_PIXEL_ID');
fbq('track', 'PageView');
</script>

• Trigger: All Pages
• Save and Submit container

3. Configure HubSpot Variables

Create GTM variables to capture HubSpot data:

• Form ID: Custom JavaScript to extract form data
• Page type: Use URL patterns
• Contact properties: Via HubSpot API

Method 3: HubSpot CMS Theme Integration

For CMS Hub Professional/Enterprise with custom themes.

Implementation Steps

1. Access Theme Files

In HubSpot:

• Navigate to Marketing > Files and Templates > Design Tools
• Select your theme

2. Edit Base Template

Add pixel code to your base HTML template (usually base.html):

<!doctype html>
<html lang="{{ html_lang }}" {{ html_lang_dir }}>
<head>
  <meta charset="utf-8">
  <title>{{ page_meta.html_title }}</title>
  {{ standard_header_includes }}

  <!-- Meta Pixel Code -->
  <script>
  !function(f,b,e,v,n,t,s)
  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?
  n.callMethod.apply(n,arguments):n.queue.push(arguments)};
  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';
  n.queue=[];t=b.createElement(e);t.async=!0;
  t.src=v;s=b.getElementsByTagName(e)[0];
  s.parentNode.insertBefore(t,s)}(window, document,'script',
  'https://connect.facebook.net/en_US/fbevents.js');
  fbq('init', 'YOUR_PIXEL_ID');
  fbq('track', 'PageView');
  </script>
</head>

3. Publish Theme

Publish changes to make them live.

Standard Events Implementation

PageView Event

Automatically tracked with base pixel. Enhanced with HubSpot context:

<script>
fbq('track', 'PageView', {
  page_type: '{{ content.template_type }}',
  content_id: '{{ content.id }}'
});
</script>

ViewContent Event

Track blog post and landing page views:

{% if content.template_type == "blog_post" %}
<script>
fbq('track', 'ViewContent', {
  content_name: '{{ content.name }}',
  content_category: '{{ content.blog_post_author }}',
  content_ids: ['{{ content.id }}'],
  content_type: 'blog_post'
});
</script>
{% endif %}

Lead Event - HubSpot Forms

Track form submissions using HubSpot's Forms API:

<script>
// Listen for HubSpot form submissions
window.addEventListener('message', function(event) {
  if(event.data.type === 'hsFormCallback' && event.data.eventName === 'onFormSubmitted') {
    fbq('track', 'Lead', {
      content_name: event.data.data.formGuid || 'form_submission'
    });
  }
});
</script>

Alternative Form Tracking (jQuery)

For forms embedded via jQuery:

<script>
$(document).ready(function() {
  window.addEventListener('message', function(event) {
    if (event.data.type === 'hsFormCallback') {
      if (event.data.eventName === 'onFormSubmit') {
        fbq('track', 'Lead', {
          form_id: event.data.id
        });
      }
    }
  });
});
</script>

CompleteRegistration Event

Track when leads convert to Marketing Qualified Leads (MQL):

<script>
// Track MQL conversions
// Requires HubSpot contact property integration
if ({{ contact.hs_lifecyclestage_lead_date }}) {
  fbq('track', 'CompleteRegistration');
}
</script>

Schedule Event

Track meeting bookings via HubSpot Meetings:

<script>
// Listen for meeting bookings
window.addEventListener('message', function(event) {
  if (event.data.meetingBookSucceeded) {
    fbq('track', 'Schedule', {
      content_name: 'Meeting Booked'
    });
  }
});
</script>

Purchase Event

For HubSpot Commerce Hub or custom checkout:

{% if content.template_type == "checkout_confirmation" %}
<script>
fbq('track', 'Purchase', {
  value: {{ order.total }},
  currency: 'USD',
  content_ids: [{% for item in order.line_items %}'{{ item.sku }}'{% if not loop.last %},{% endif %}{% endfor %}],
  content_type: 'product',
  num_items: {{ order.line_items|length }}
});
</script>
{% endif %}

Advanced Matching with HubSpot Contacts

Improve attribution by sending hashed contact information:

<script>
{% if contact %}
// Hash contact email for better matching
async function hashValue(value) {
  const encoder = new TextEncoder();
  const data = encoder.encode(value.toLowerCase().trim());
  const hashBuffer = await crypto.subtle.digest('SHA-256', data);
  const hashArray = Array.from(new Uint8Array(hashBuffer));
  return hashArray.map(b => b.toString(16).padStart(2, '0')).join('');
}

(async function() {
  const hashedEmail = await hashValue('{{ contact.email }}');
  const hashedFirstName = '{{ contact.firstname }}' ? await hashValue('{{ contact.firstname }}') : null;
  const hashedLastName = '{{ contact.lastname }}' ? await hashValue('{{ contact.lastname }}') : null;

  fbq('init', 'YOUR_PIXEL_ID', {
    em: hashedEmail,
    fn: hashedFirstName,
    ln: hashedLastName,
    ct: '{{ contact.city }}' ? await hashValue('{{ contact.city }}') : null,
    st: '{{ contact.state }}' ? await hashValue('{{ contact.state }}') : null,
    zp: '{{ contact.zip }}' ? await hashValue('{{ contact.zip }}') : null
  });
})();
{% endif %}
</script>

Conversions API (Server-Side Tracking)

Implement CAPI for more reliable tracking with HubSpot workflows.

Prerequisites

• HubSpot Professional or Enterprise
• Access to HubSpot Workflows
• Webhook endpoint to receive HubSpot data
• Facebook Business SDK

Implementation

1. Create Webhook Endpoint

Set up a server to receive HubSpot webhook data:

const express = require('express');
const bizSdk = require('facebook-nodejs-business-sdk');
const app = express();

app.use(express.json());

const access_token = process.env.FB_ACCESS_TOKEN;
const pixel_id = process.env.FB_PIXEL_ID;

const ServerEvent = bizSdk.ServerEvent;
const EventRequest = bizSdk.EventRequest;
const UserData = bizSdk.UserData;
const CustomData = bizSdk.CustomData;

bizSdk.FacebookAdsApi.init(access_token);

app.post('/webhooks/hubspot/form-submission', async (req, res) => {
  try {
    const submission = req.body;

    const userData = (new UserData())
      .setEmail(submission.submittedAt.email)
      .setFirstName(submission.submittedAt.firstname)
      .setLastName(submission.submittedAt.lastname)
      .setCity(submission.submittedAt.city)
      .setState(submission.submittedAt.state)
      .setZipCode(submission.submittedAt.zip)
      .setClientIpAddress(submission.context?.ipAddress)
      .setClientUserAgent(submission.context?.userAgent);

    const customData = (new CustomData())
      .setContentName(submission.formGuid);

    const serverEvent = (new ServerEvent())
      .setEventName('Lead')
      .setEventTime(Math.floor(submission.submittedAt / 1000))
      .setUserData(userData)
      .setCustomData(customData)
      .setEventSourceUrl(submission.context?.pageUrl)
      .setActionSource('website');

    const eventsData = [serverEvent];
    const eventRequest = (new EventRequest(access_token, pixel_id))
      .setEvents(eventsData);

    const response = await eventRequest.execute();
    console.log('Conversion API response:', response);

    res.status(200).send('Event sent');
  } catch (error) {
    console.error('Error:', error);
    res.status(500).send('Error');
  }
});

app.listen(3000, () => console.log('Webhook server running on port 3000'));

2. Configure HubSpot Workflow

In HubSpot:

• Automation > Workflows > Create workflow
• Enrollment trigger: Form submission
• Action: Send a webhook
• URL: Your webhook endpoint
• Method: POST
• Include contact properties in request body

3. Test Integration

Submit a test form and verify:

• Webhook receives data
• Conversion API receives event
• Event appears in Facebook Events Manager Test Events

HubSpot CRM List Syncing

Custom Audiences from HubSpot Lists

1. Export HubSpot List

• Navigate to Contacts > Lists
• Select target list
• Export > Export all contacts
• Download CSV with email addresses

2. Upload to Facebook

• Go to Facebook Ads Manager
• Audiences > Create Audience > Custom Audience
• Select Customer List
• Upload CSV file
• Map email column
• Create audience

Automated Sync (Advanced)

Use HubSpot API and Facebook Marketing API:

const hubspot = require('@hubspot/api-client');
const bizSdk = require('facebook-nodejs-business-sdk');

// Fetch contacts from HubSpot list
async function syncHubSpotListToFacebook(listId, audienceId) {
  const hubspotClient = new hubspot.Client({ accessToken: HUBSPOT_TOKEN });

  const contactsResponse = await hubspotClient.crm.lists.listContacts(listId);
  const emails = contactsResponse.results.map(contact => contact.properties.email);

  // Upload to Facebook Custom Audience
  const CustomAudience = bizSdk.CustomAudience;
  const audience = new CustomAudience(audienceId);

  await audience.addUsers(
    ['EMAIL'],
    [emails]
  );

  console.log(`Synced ${emails.length} contacts to Facebook audience`);
}

Landing Page Tracking

Track Landing Page Performance

{% if content.template_type == "landing_page" %}
<script>
fbq('track', 'ViewContent', {
  content_name: '{{ content.name }}',
  content_category: 'landing_page',
  content_ids: ['{{ content.id }}']
});
</script>
{% endif %}

Track CTA Clicks

<script>
// Track CTA button clicks
document.querySelectorAll('.hs-cta-wrapper a').forEach(function(cta) {
  cta.addEventListener('click', function() {
    fbq('trackCustom', 'CTAClick', {
      cta_id: this.getAttribute('data-hs-cta-id'),
      cta_text: this.innerText
    });
  });
});
</script>

E-commerce Tracking (HubSpot Commerce Hub)

AddToCart Event

<script>
// Track add to cart actions
document.addEventListener('cart_item_added', function(event) {
  fbq('track', 'AddToCart', {
    content_ids: [event.detail.sku],
    content_name: event.detail.name,
    value: event.detail.price,
    currency: 'USD'
  });
});
</script>

InitiateCheckout Event

<script>
{% if content.template_type == "checkout" %}
fbq('track', 'InitiateCheckout', {
  content_ids: [{% for item in cart.items %}'{{ item.sku }}'{% if not loop.last %},{% endif %}{% endfor %}],
  num_items: {{ cart.items|length }},
  value: {{ cart.total }},
  currency: 'USD'
});
{% endif %}
</script>

Troubleshooting

Pixel Not Firing

Check Tracking Code Settings:

1. Go to Settings > Tracking & Analytics > Tracking Code
2. Verify pixel code is in Footer HTML
3. Check for JavaScript errors in console

Verify Page Type:

// Check HubSpot page type
console.log('{{ content.template_type }}');

Test Pixel Loading:

// In browser console
console.log(typeof fbq);
// Should output: "function"

Events Not Recording

Check Form Events:

// Monitor all HubSpot form events
window.addEventListener('message', function(event) {
  console.log('HubSpot event:', event.data);
});

Enable Debug Mode:

fbq('init', 'YOUR_PIXEL_ID', {}, {
  debug: true
});

Common Error Messages

"fbq is not defined"

• Pixel code not loaded properly
• Check for ad blockers
• Verify code is in Footer HTML, not Header

Forms Not Tracking

• Ensure form submission listener is active
• Check for JavaScript errors
• Verify form is HubSpot form (not custom HTML)

Advanced Matching Issues

• Hash values client-side
• Don't send PII unhashed
• Verify contact properties exist

Privacy and Compliance

GDPR Compliance with HubSpot

HubSpot has built-in privacy features. Integrate consent:

<script>
// Check HubSpot cookie consent
if (window._hsq && window._hsq.push) {
  window._hsq.push(['addPrivacyConsentListener', function(consent) {
    if (consent.allowed) {
      // Load Meta Pixel
      !function(f,b,e,v,n,t,s){...}
    }
  }]);
}
</script>

HubSpot Privacy Policy Integration

Link to your privacy policy:

• Settings > Privacy & Consent
• Enable cookie banner
• Configure tracking consent options

Data Processing Options

For CCPA compliance:

fbq('dataProcessingOptions', ['LDU'], 1, 1000);

Performance Optimization

Lazy Load After HubSpot Scripts

<script>
// Wait for HubSpot to load first
document.addEventListener('DOMContentLoaded', function() {
  setTimeout(function() {
    // Load Meta Pixel
    !function(f,b,e,v,n,t,s){...}
  }, 1000);
});
</script>

Conditional Loading by Page Type

{% if content.template_type in ["landing_page", "blog_post"] %}
<!-- Only load pixel on landing pages and blog posts -->
<script>
  !function(f,b,e,v,n,t,s){...}
</script>
{% endif %}
