Knock2 Public API

Your buyer intent data. Anywhere you build.

The Knock2 API gives you direct access to every identified visitor, account, score, and page visit. Pipe it into your CRM, your data warehouse, your product, or your own AI workflows.

BUILT ON YOUR PIPELINE

Every visitor, structured and ready to use

Knock2 identifies the companies and people evaluating you. The API makes all of it yours: accounts, contacts, lead scores, and full page visit history, delivered as clean JSON.

  • Pull identified accounts and contacts into any system
  • See exactly which pages a buyer viewed, and when
  • Query lead scores to prioritize who gets attention first

REAL-TIME, NOT BATCH

Know the moment a buyer shows up

Don't poll for data. Subscribe to webhooks and Knock2 pushes events to you the instant they happen. A target account lands on your pricing page, a contact gets identified, a lead score jumps. Your systems react in seconds, not at the next sync.

  • account.identified, a new company hits your site
  • contact.identified, a real person with name and role
  • score.changed, a warm account just got hotter

YOUR SEGMENTS, EVERYWHERE

Filter once. Use it across your stack.

Build a segment in the Knock2 dashboard, like fintech companies over 200 employees that visited pricing this month, then reuse it instantly through the API. Every system you run works from one definition of a good lead.

  • Apply saved filter sets to any API query
  • Create and manage segments programmatically
  • Keep your CRM, ad audiences, and outbound tools in sync

FOR PLATFORMS AND PARTNERS

Put visitor identification inside your product

Building a sales tool, agency platform, or marketing suite? Provision Knock2 for your own customers with a single API call. Each customer gets their own tenant, tracking script, and API key. You get a new capability to sell, without building identification infrastructure from scratch.

  • Onboard a new customer in one request
  • Every tenant fully isolated with its own key
  • Deactivate instantly when a customer churns
