HubSpot integration

HubSpot → Settings → Integrations → Private apps → Create. Scopes: crm.objects.contacts (read/write), crm.objects.companies (read/write), crm.objects.notes (write). Paste the access token in Integrations. We create or update the contact by email, never overwrite a field that already has a value, and add a timeline note with the pages viewed so your workflows can trigger on it. Custom properties dz_intent_score, dz_last_identified, dz_profile_url, dz_confidence, dz_hot_pages are written if they exist.
