Google Tag Manager

Learn how to integrate Oppla with Google Tag Manager (GTM) for easier tracking implementation.

​
Setup

​
1. Create a Custom HTML Tag

In Google Tag Manager:
  1. Go to Tags > New
  2. Click on Tag Configuration
  3. Select “Custom HTML”
  4. Add the Oppla tracking code:
<script>
  (function(p,r,o,d,i,o){p[i]=p[i]||function(){(p[i].q=p[i].q||[]).push(arguments)};
  o=r.createElement('script');o.async=1;o.src=d;r.head.appendChild(o);
  })(window,document,'script','https://cdn.oppla.app/tracker.js','oppla');

  window.oppla.init('YOUR_PROJECT_ID');
</script>

​
2. Configure Triggers

Set up triggers for when the tag should fire:
  • All Pages: For basic tracking
  • Specific Pages: For targeted tracking
  • User Interactions: For event tracking

​
Event Tracking

​
Track Page Views

// In GTM Custom HTML tag
window.oppla.track('Page Viewed', {
  path: window.location.pathname,
  title: document.title,
  referrer: document.referrer
});

​
Track User Interactions

// In GTM Custom HTML tag
window.oppla.track('Button Clicked', {
  buttonId: '{{Click ID}}',
  buttonText: '{{Click Text}}',
  page: '{{Page Path}}'
});

​
Data Layer Integration

​
Push to Data Layer

// In your website code
window.dataLayer.push({
  'event': 'opplaEvent',
  'eventName': 'Purchase Completed',
  'eventProperties': {
    'orderId': '12345',
    'amount': 99.99
  }
});

​
Listen for Data Layer Events

// In GTM Custom HTML tag
window.dataLayer.push = function(e) {
  if (e.event === 'opplaEvent') {
    window.oppla.track(e.eventName, e.eventProperties);
  }
};

​
User Identification

​
Identify Users

// In GTM Custom HTML tag
window.oppla.identify({
  userId: '{{User ID}}',
  traits: {
    name: '{{User Name}}',
    email: '{{User Email}}',
    plan: '{{User Plan}}'
  }
});

​
Best Practices

  1. Use Variables: Store Oppla project ID in GTM variables
  2. Test in Preview: Always test in GTM preview mode
  3. Use Data Layer: Push events to data layer for consistency
  4. Monitor Performance: Check tag loading impact

​
Common Issues

​
Tag Not Loading

  • Check GTM container code is properly installed
  • Verify trigger conditions
  • Check for JavaScript errors

​
Events Not Tracking

  • Verify data layer pushes
  • Check event names and properties
  • Ensure proper timing of tag loading
