If you build a B2B SaaS — CRM, marketing automation, analytics, agency platform, ABM tool — OEM visitor identification is how you add a high-value product surface without building the data graph yourself. This guide covers how an OEM API works, what the integration looks like, and how the Happierleads OEM program is structured.
What OEM means in this context
OEM (original equipment manufacturer) means Happierleads' visitor identification technology runs inside your product, surfaced under your brand. Your users never see "Powered by Happierleads" — they see identified visitors as a native capability of your platform.

Why build via OEM instead of from scratch
- Data graph takes years. A credible visitor identification product requires a 175M+ verified contact graph and a 20B+ IP-to-company map, continuously re-verified. Building this from zero is a multi-year, multi-million-dollar commitment.
- Verification infrastructure is expensive. 8+ verification providers, continuous re-verification, LinkedIn cross-checks.
- Compliance takes legal runway. GDPR, CCPA, legitimate interest documentation, DPAs.
- You can ship it next quarter via API.
What the API exposes
- Visitor identification endpoint: Submit an IP + first-party cookie token, get back company + likely-person data.
- Company enrichment: Submit a domain, get firmographics, technographics, funding, committee view.
- Contact enrichment: Submit a name + domain, get a verified email + LinkedIn + tenure.
- Email waterfall verification: Submit an email, get a consensus confidence score from 8+ providers.
- LinkedIn real-time check: Submit a person, get employment + role + tenure live.
- Webhooks: Push identified visitors into your product as they land.

How the integration usually looks
- Your customer drops your tracking snippet on their site (unchanged for them).
- Your snippet forwards IP + first-party cookie to the Happierleads API.
- The API returns identification data in 1–2 seconds.
- You display it inside your product.
- Your user never knows Happierleads is involved — it's a native feature.
What your product gets
- A differentiator against competitors without a data graph.
- A justification for higher-tier plans.
- Stickiness — customers don't switch away from products that reveal their anonymous visitors.
- Expansion revenue via add-on enrichment credits.
Commercial structure
- Volume-based pricing per lookup / per contact enriched / per verification.
- No per-seat or per-customer fees — you pay for the data you consume.
