FAQ

Frequently asked questions

How does the HubSpot integration work?

Native two-way integration. When an identified visitor matches a HubSpot contact, we enrich the record with visit data, lead score, pages viewed, and device details. For new visitors, you control whether Knock2 creates a new contact automatically (via a workflow trigger) or routes them to a list for review.

Record source, source detail, lifecycle stage, and contact owner are all configurable in the integration settings. Knock2 doesn't consume your HubSpot enrichment credits.

How does the Salesforce integration work?

Native integration with per-user OAuth. Each rep connects their own Salesforce credentials so attribution and record ownership stay correct. Identified visitors can be created as leads or contacts, associated with existing accounts, and deduplicated against your existing CRM data.

Account matching uses domain and company name. You can filter out active customers, open opportunities, or any CRM stage so Knock2 only surfaces new-business signal.

What if I use tools other than HubSpot or Salesforce?

Native integrations are built for HubSpot, Salesforce, Slack, Apollo, Outreach, Lemlist, Instantly, and Clay. For anything not on that list, webhooks cover Zapier, Make, n8n, and any other tool that accepts them.

Many teams without a traditional CRM use Knock2 with just Slack and Google Sheets, routing high-intent visitors to Slack channels and logging everything to sheets for rep follow-up.

Can I control Slack notification volume?

Yes. Notifications are filter-driven, so you only get alerts for visitors that matter. Most teams set a lead score threshold (for example, anyone above 75) or a page-visit filter (pricing page, demo page, specific product pages) to ensure Slack only fires on high-intent signal.

Below that threshold, visitors flow into your CRM or a dashboard view for batch review instead of live alerts.

Does Knock2 consume my HubSpot or Apollo credits?

No. Knock2 operates on its own credit pool and doesn't touch enrichment credits from HubSpot, Apollo, Clearbit, or any other tool. When Knock2 pushes data to your CRM, it's writing contact records directly using our own identification and enrichment pipeline.

Is this actually legal?

Yes. Knock2 uses the same underlying technology as ad retargeting pixels from Meta, Google, and LinkedIn. Our data comes from consented publisher login co-ops, tying identity to an anonymous device fingerprint.
