If you're not using our WordPress plugin — or your form provider isn’t supported — you can send form submissions to LeadTrackr using the Leads API tag in Server-side Google Tag Manager (sGTM).

💡
Using WordPress?
If your form provider is supported by our WordPress plugin, we strongly recommend using it instead of the sGTM setup.
The plugin sends form submissions server-to-server, which means:
- 100% of submissions are tracked reliably
- Tracking is not blocked by adblockers, ITP, or browser limitations
- No client-side scripts are required
✅ Easier setup, better accuracy, no sGTM or custom events needed

⚙️ Step 1: Add the LeadTrackr Tag Template to Your sGTM Container
- Go to your server container in Tag Manager
- Click Templates → Search Gallery
- Look for LeadTrackr Leads API
- Click Add to Workspace
This will add the custom tag type to your sGTM environment.

📝 Step 2: Create a New LeadTrackr Tag
- Go to Tags and click New
- Select LeadTrackr Leads API as the tag type
- Fill in the required fields:
- Project ID
- Form name (descriptive label)
- Any custom form fields or user data fields you want to pass along (e.g. email, phone, message)

💡
Where to find your Project ID
- Go to app.leadtrackr.io/dashboard/projects
- Open the project you want to connect
- Your Project ID is visible in the URL
- Example:
https://app.leadtrackr.io/projects/16
→ project ID = 16

🎯 Step 3: Add a Trigger
Attach a trigger that sends the lead event to leadtrackr.
