Sitecore JSS Tracking API for Analytics: The Complete Guide

With the rise of headless and JAMstack architectures, especially in Sitecore JSS applications, traditional analytics tracking methods often fall short. Enter Sitecore JSS Tracking API — a specialized solution enabling you to integrate Sitecore Experience Analytics even in headless or static-generated applications.

What Is the JSS Tracking API?

The JSS Tracking API is a client-facing RESTful API provided by Sitecore that allows developers to submit user interactions, goals, page views, and custom events to the Sitecore xDB (Experience Database), even when running a headless or decoupled frontend like a Next.js app.

Why Use the JSS Tracking API?

In traditional Sitecore setups, tracking is embedded in the server-side rendering pipeline. But in JSS apps — especially those built with SSG or SPA frameworks — tracking must be handled client-side.

Key Benefits:

• Enables analytics in headless apps
• Preserves xDB capabilities (engagement value, goals, personalization)
• Works without full page reloads
• Supports custom events and funnel tracking

How to Use the JSS Tracking API?

Make a POST request to:

/sitecore/api/interaction/register

Sample Payload:

{
  "contact": {
    "identifier": {
      "source": "email",
      "identifier": "[email protected]"
    }
  },
  "events": [
    {
      "definitionId": "goal-guid",
      "timestamp": "2025-05-14T10:00:00Z"
    }
  ],
  "pageVisit": {
    "itemId": "{page-item-id}",
    "duration": 5
  }
}

Basic Steps:

1. Identify the contact
2. Send page visit or goal data using fetch or axios
3. Optionally include campaign or outcome
4. Ensure @sitecore-jss/tracking is installed
5. Use session or visitor cookies to correlate events

No batching	Each event is sent as an individual request
CORS and Auth	Requires CORS setup and appropriate access rights
No default page visit logging	Must implement custom logic for tracking
Rendering personalization not supported	Does not handle dynamic component variants
SSG tracking delay	Data is sent only after hydration

Fit for SSG vs SSR

Mode	Fit?	Details
SSG (Static Site Generation)	Yes (with care)	Client-side tracking after hydration
SSR (Server Side Rendering)	Yes	Tracking can be enriched server-side
SPA (Single Page Application)	Yes (best fit)	Track on route change using hooks

Recommended Implementation Approach

1. Setup Sitecore JSS App with xDB Enabled
2. Configure CORS for your frontend domain
3. Use @sitecore-jss/tracking or custom HTTP calls
4. Track page views via router events or useEffect
5. Trigger goals and events via click handlers
6. Ensure GDPR/consent requirements are met
7. Verify events in Experience Analytics and Profile
