What is OEM Visitor Identification?

OEM (Original Equipment Manufacturer) licensing allows your agency to embed visitor identification technology into your product and resell it as your own. Unlike white labeling (which provides a pre-built dashboard), OEM APIs give you raw data and complete flexibility to build custom solutions.

Perfect for agencies that:

  • Have existing dashboards or client portals
  • Want complete control over UX and branding
  • Need to integrate visitor data with proprietary systems
  • Serve enterprise clients requiring custom reporting

HappierLeads OEM API Capabilities

RESTful API Architecture

Our API provides programmatic access to all visitor identification features:

  • Visitor Identification: GET real-time and historical visitor data
  • Contact Enrichment: POST company domains to enrich with full contact details
  • Lead Scoring: Access behavioral scores and buying intent signals
  • Webhook Events: Receive instant notifications when high-value visitors land on site
  • Batch Operations: Process large datasets efficiently

Person-Level Data Schema

Each API response includes:

  • Individual contact details (name, email, phone, LinkedIn)
  • Company information (name, size, industry, revenue)
  • Visit metadata (pages viewed, time on site, referral source)
  • Engagement scoring (0-100 based on behavior)
  • Technographic data (technologies used by the company)

Real-Time Webhooks

Configure webhooks to push visitor data to your systems instantly:

  • New visitor identified
  • High-value prospect detected (based on ICP criteria)
  • Visitor returns to site
  • Specific page viewed (e.g., pricing, demo)

Common OEM Use Cases for Agencies

1. Integrated Dashboard for Agency Clients

Build visitor identification into your existing client portal. Show identified visitors alongside SEO metrics, ad performance, and website analytics in one unified dashboard.

Implementation: Fetch visitor data via API, render in your UI, no HappierLeads branding visible.

2. Automated Lead Delivery System

Use webhooks to automatically push identified visitors into client CRMs or trigger email sequences. Build workflows that activate based on visitor behavior.

Example: When a visitor views pricing page 3+ times, automatically create a high-priority lead in Salesforce and notify the sales rep.

3. Custom Reporting & Analytics

Create industry-specific reports that combine visitor identification data with other metrics. Build custom dashboards for verticals like real estate, manufacturing, or SaaS.

4. Lead Scoring Models

Use API data to build proprietary lead scoring algorithms. Combine visitor behavior with firmographic data, engagement history, and your own business logic.

API Integration Steps

Step 1: Authentication

Obtain API credentials from the partner dashboard. All requests require Bearer token authentication:

Authorization: Bearer {YOUR_API_TOKEN}

Step 2: Install Tracking Script

Add HappierLeads tracking script to client websites. This runs in the background and identifies visitors without interfering with site performance.

Step 3: Fetch Visitor Data

Make GET requests to retrieve identified visitors:

GET /api/v1/websites/{websiteId}/visitors?limit=100

Filter by date range, engagement score, company size, or any other parameter.

Step 4: Enrich & Display

Process API responses and display in your application. Map fields to your data model, apply business rules, and render in your UI.

Step 5: Configure Webhooks (Optional)

Set up webhook endpoints to receive real-time visitor notifications. Perfect for triggering automated workflows.

How is this different from Clearbit, 6Sense, or DemandBase’s Website Identity Solutions?

At Happierleads, we use a completely different approach—our fully-permissioned, proprietary publisher network—allowing us to identify the exact individuals visiting your website. Discover more about how we identify your site visitors here.

Why is Happierleads ranked number #1 for data quality on G2 and Capterra?

What about U.S. state privacy laws, like the California CCPA and CPRA?
