Unbounce → GoHighLevel Integration Guide

I see this integration broken in about 30% of the agencies I work with. Usually it’s because they tried to set up the native integration, it looked like it worked, but leads have been silently failing for weeks. The client keeps asking why their “high-converting” landing pages aren’t generating pipeline, and nobody thought to check if the leads actually made it into GoHighLevel.

The webhook approach is most reliable here — GoHighLevel’s webhook system is solid, and Unbounce’s form handlers play nice with external APIs. But there are three ways to do this, and I’ll walk you through each one.

What You’ll Have Working By The End

Prerequisites

Step 1: Choose Your Integration Method

You’ve got three realistic options here. Skip the native integration unless you’re dealing with a very simple use case — it breaks too often.

Zapier (Recommended for most setups): Easiest to set up and maintain. Built-in error handling and retry logic. Costs $20-50/month depending on volume but worth it for reliability.

Direct Webhook: Most reliable for high-volume setups. Requires some technical comfort but gives you complete control over field mapping and error handling.

Native GoHighLevel Integration: Exists in Unbounce’s integrations panel, but I’ve seen it fail silently when GoHighLevel updates their API. Only use this for low-stakes testing.

I’m starting with Zapier because it works for 80% of setups, then covering webhooks for the technical folks.

Step 2: Set Up GoHighLevel to Receive Leads

First, you need somewhere for the leads to go. In GoHighLevel:

  1. Go to Settings → Integrations → Webhooks
  2. Click Create Webhook
  3. Name it “Unbounce Leads” or similar
  4. Set the Type to “Contact”
  5. Choose your default Pipeline and Stage for new leads
  6. Copy the webhook URL — you’ll need this in Unbounce

The webhook URL looks like: https://services.leadconnectorhq.com/hooks/webhook-key-here

Field mapping setup: In the webhook settings, map these fields if you want UTM data:

Don’t skip this — knowing which landing page generated each lead is crucial for reporting.

Step 3: Configure Unbounce Form Submission

In your Unbounce landing page editor:

  1. Select your form element
  2. Go to Form Confirmation in the right panel
  3. Choose Go to URL (not “Show Confirmation Dialog”)
  4. Set the URL to your GoHighLevel webhook URL
  5. Check Include form data in URL

This sends the form data as URL parameters to your webhook. The webhook URL becomes:

https://services.leadconnectorhq.com/hooks/webhook-key-here?email=john@example.com&first_name=John&phone=555-123-4567

Alternative webhook approach: If you want more control, use Unbounce Scripts instead:

  1. Go to Landing Pages → [Your Page] → Scripts
  2. Add this to Before Body End Tag:
<script>
document.addEventListener('DOMContentLoaded', function() {
    const form = document.getElementById('lp-pom-form-1');
    if (form) {
        form.addEventListener('submit', function(e) {
            e.preventDefault();
            
            const formData = new FormData(form);
            const data = {
                email: formData.get('email'),
                first_name: formData.get('name'), // Adjust field names
                phone: formData.get('phone'),
                utm_source: getUrlParameter('utm_source'),
                utm_campaign: getUrlParameter('utm_campaign'),
                landing_page: window.location.pathname
            };
            
            fetch('YOUR_GOHIGHLEVEL_WEBHOOK_URL', {
                method: 'POST',
                headers: {'Content-Type': 'application/json'},
                body: JSON.stringify(data)
            }).then(() => {
                window.location.href = '/thank-you'; // Your thank you page
            });
        });
    }
});

function getUrlParameter(name) {
    const urlParams = new URLSearchParams(window.location.search);
    return urlParams.get(name) || '';
}
</script>

This gives you better error handling and lets you include UTM parameters automatically.

Step 4: Zapier Integration (Alternative Method)

If you prefer Zapier over direct webhooks:

  1. Create new Zap: Unbounce → GoHighLevel
  2. Trigger: “New Lead in Unbounce”
  3. Connect your Unbounce account and select your landing page
  4. Action: “Create Contact in GoHighLevel”
  5. Connect your GoHighLevel account

Field mapping in Zapier:

Zapier pros: Built-in retry logic, error notifications, easy to modify field mapping. Zapier cons: Costs money, adds delay (usually 1-15 minutes), less control over error handling.

For agencies running multiple campaigns, Zapier is worth the cost. For single landing page setups, direct webhook is fine.

Step 5: Field Mapping Configuration

This is where most integrations break. Unbounce form field names need to match what GoHighLevel expects.

Standard Unbounce fields:

Custom fields you should add:

In GoHighLevel, create these custom fields first (Settings → Custom Fields → Contact Fields) before setting up the integration. Name them clearly: “Landing Page Source”, “UTM Campaign”, etc.

Pro tip: I always add a “Lead Source” field with the exact landing page URL. Makes it easy to track which pages are converting and debug integration issues.

Testing & Verification

Never assume this integration works without testing. Here’s how to verify:

  1. Submit a test form on your Unbounce page using a unique email
  2. Check GoHighLevel contacts within 30 seconds (webhook) or 15 minutes (Zapier)
  3. Verify field mapping — are custom fields populated correctly?
  4. Test duplicate handling — submit the same email twice, should update existing contact
  5. Check pipeline assignment — is the lead in the correct pipeline and stage?

Webhook testing: Check the webhook logs in GoHighLevel (Settings → Integrations → Webhooks → View Logs). You should see successful POST requests with 200 status codes.

Red flags:

If you see any of these, the integration isn’t working correctly even if leads are coming through.

Troubleshooting

Problem: Leads submitting but not appearing in GoHighLevel Check your webhook URL is correct and the webhook is active. Test the URL directly in a browser — you should get a GoHighLevel response, not a 404. Also verify the landing page is actually sending data to the webhook (check browser dev tools Network tab).

Problem: Duplicate contacts being created for repeat submissions Enable duplicate prevention in GoHighLevel webhook settings. Set it to match on email address and update existing contacts instead of creating new ones. This is under the webhook configuration “Duplicate Check” setting.

Problem: Custom fields (UTM data, landing page) not populating The custom fields need to exist in GoHighLevel before the webhook can populate them. Create them first in Settings → Custom Fields, then update your webhook field mapping to include them.

Problem: Phone numbers not formatting correctly GoHighLevel expects phone numbers in E.164 format (+1234567890). If Unbounce is sending (123) 456-7890 format, add a formatter in your webhook or Zapier step to clean it up.

Problem: Integration worked initially but stopped Usually means GoHighLevel API credentials expired or webhook was accidentally deleted. Check the webhook still exists and is active. If using Zapier, reconnect your GoHighLevel account — the connection probably expired.

Problem: High volume causing webhook timeouts GoHighLevel webhooks can handle ~10 requests per second. If you’re pushing more volume than that, implement a queue system or switch to their REST API with proper rate limiting. This is rare unless you’re running major traffic campaigns.

What To Do Next

Once your Unbounce leads are flowing into GoHighLevel, you’ll want to set up proper conversion tracking to measure which landing pages are generating your best leads:
