HubSpot Forms → GoHighLevel Integration Guide

I see this integration requested in probably 60% of the agency accounts I work with. The problem? Most teams set it up wrong and end up with duplicate contacts, missing pipeline assignments, or — worst case — leads that never make it to GoHighLevel at all. The frustrating part is both platforms are solid, but the connection points are more fragile than they look.

What You’ll Have Working By The End

Prerequisites

HubSpot doesn’t have a direct native integration with GoHighLevel, but they do have a workflow system that can trigger webhooks. This is actually more reliable than Zapier for most setups because it stays within HubSpot’s infrastructure.

Set Up the Webhook Endpoint in GoHighLevel

First, grab your GoHighLevel webhook URL:

  1. Go to Settings → Integrations → Webhooks
  2. Click “Add Webhook”
  3. Set trigger to “Contact Created”
  4. Copy the webhook URL (looks like https://hooks.gohighlevel.com/hooks/[your-id])

Create the HubSpot Workflow

  1. In HubSpot, go to Automation → Workflows
  2. Create a new contact-based workflow
  3. Set enrollment trigger: “Form submission” → select your specific forms
  4. Add action: “Send data to external system”
  5. Configure the webhook:
{
  "contact": {
    "email": "{{contact.email}}",
    "firstName": "{{contact.firstname}}",
    "lastName": "{{contact.lastname}}",
    "phone": "{{contact.phone}}",
    "companyName": "{{contact.company}}",
    "source": "HubSpot Form",
    "customField1": "{{contact.your_custom_property}}"
  },
  "pipeline": "your-pipeline-id",
  "stage": "your-initial-stage-id"
}
  1. Set the webhook URL to your GoHighLevel endpoint
  2. Turn on the workflow

The workflow will fire within 5-10 seconds of form submission. I’ve seen this setup handle 500+ leads per day without issues.

Method 2: Zapier Integration

If you prefer a no-code solution, Zapier works well here. The connection is stable, though you’ll hit rate limits on the free plan pretty quickly.

Set Up the Zap

  1. Create new Zap with HubSpot as trigger
  2. Choose “New Form Submission” trigger
  3. Connect your HubSpot account and test
  4. Select GoHighLevel as action app
  5. Choose “Create Contact” action
  6. Map your fields:

Required Mappings:

Optional but Recommended:

  1. Set pipeline and stage assignment in GoHighLevel action
  2. Turn on the Zap

Test by submitting your form and checking that the contact appears in GoHighLevel within 2-3 minutes.

Method 3: Direct API Integration

For agencies handling high volume, a direct API integration gives you the most control. You’ll need developer access for this approach.

Set Up the Webhook Listener

Create a webhook endpoint that receives HubSpot form submissions and posts to GoHighLevel:

// Example webhook handler (Node.js)
app.post('/hubspot-webhook', async (req, res) => {
  const formData = req.body;
  
  // Extract contact data
  const contactData = {
    email: formData.submittedAt.email,
    firstName: formData.submittedAt.firstname,
    lastName: formData.submittedAt.lastname,
    phone: formData.submittedAt.phone,
    companyName: formData.submittedAt.company,
    source: 'HubSpot Form',
    customField1: formData.submittedAt.custom_property
  };

  // Send to GoHighLevel
  const ghlResponse = await fetch('https://rest.gohighlevel.com/v1/contacts/', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.GHL_API_KEY}`,
      'Content-Type': 'application/json'
    },
    body: JSON.stringify(contactData)
  });

  if (ghlResponse.ok) {
    console.log('Contact synced to GoHighLevel');
    res.status(200).send('Success');
  } else {
    console.error('Failed to sync contact');
    res.status(500).send('Error');
  }
});

Configure HubSpot Form Webhooks

  1. In HubSpot, go to Settings → Data Management → Properties
  2. Find your form and click “Actions” → “View form analytics”
  3. Go to Options → Set up webhook notifications
  4. Add your webhook endpoint URL
  5. Select which forms should trigger the webhook

The API approach handles about 95% of submissions successfully in my experience, with failures usually due to duplicate email addresses in GoHighLevel.

Testing & Verification

Verify the Integration is Working

  1. Submit a test form with fake but realistic data
  2. Check HubSpot - confirm the contact was created (should be immediate)
  3. Check GoHighLevel - contact should appear within 30 seconds to 2 minutes
  4. Verify field mapping - all mapped fields should transfer correctly
  5. Check pipeline assignment - contact should be in the correct pipeline and stage

Cross-Check the Numbers

Every Friday, I recommend doing a quick count comparison:

Acceptable variance is 2-5%. If you’re seeing 10%+ variance, you have sync failures that need investigating.

Red Flags That Indicate Problems

Troubleshooting

Problem: Contacts created in GoHighLevel but missing custom field data Solution: Check your field mapping configuration. GoHighLevel requires exact API field names. Go to Settings → Custom Fields in GoHighLevel to get the correct API field names (usually lowercase with underscores).

Problem: Duplicate contacts being created in GoHighLevel Solution: GoHighLevel’s duplicate detection relies on email addresses. Enable “Update existing contact if email exists” in your integration settings. For Zapier, use “Find or Create Contact” action instead of “Create Contact.”

Problem: Integration stops working after a few weeks Solution: Usually an API key expiration issue. GoHighLevel API keys don’t expire, but HubSpot access tokens do. If using custom webhooks, implement token refresh logic. For Zapier, reconnect your accounts.

Problem: Form submissions not triggering the integration Solution: Check that your trigger is set correctly. HubSpot forms on external sites sometimes don’t fire workflows properly. Add a backup trigger for “Contact created” with additional filter “Recent form submission date is known.”

Problem: Contacts created but not assigned to sales team Solution: GoHighLevel pipeline assignment must be configured in each integration method. Check that you’re passing both pipeline ID and stage ID. You can find these in GoHighLevel under Settings → Pipelines.

Problem: Phone numbers not formatting correctly in GoHighLevel Solution: GoHighLevel expects phone numbers in E.164 format (+1234567890). If your HubSpot forms collect phone numbers in different formats, add a formatting step in your integration to clean them up.

What To Do Next

Once your HubSpot Forms are syncing to GoHighLevel, you’ll probably want to set up GoHighLevel conversion tracking to measure which marketing channels are driving your best leads. You might also need HubSpot Forms Google Ads conversion tracking to optimize your ad spend.

If you’re using multiple form tools, consider setting up HubSpot Forms to Salesforce or HubSpot Forms to ActiveCampaign integrations for backup lead capture.
