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

Step 1: Add the LeadTrackr Tag Template to Your sGTM Container

  1. Go to your server container in Tag Manager
  2. Click TemplatesSearch Gallery
  3. Look for LeadTrackr Leads API
  4. Click Add to Workspace

Step 2: Create a New LeadTrackr Tag

  1. Go to Tags and click New
  2. Select LeadTrackr Leads API as the tag type
  3. 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

  1. Go to app.leadtrackr.io/dashboard/projects
  2. Open the project you want to connect
  3. 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. This is typically a custom event, such as form_submission, or an incoming HTTP request handled by your sGTM client.

Step 4: Publish Your Container

Once your tag and trigger are configured, publish your sGTM container. Your form submissions are now sent to LeadTrackr via the Leads API, ready to be rated, qualified, and pushed to ad platforms as offline conversions.
