"content": "## HubSpot to Klaviyo Sync Bridge using n8n\n\nIf you run HubSpot for CRM and Klaviyo for email, you know the pain -- new contacts sit in HubSpot without ever reaching Klaviyo, sequences never fire on time, and your lists go stale. This workflow fixes that permanently.\n\n### How it works\n\n1. HubSpot fires a webhook the moment a new contact is created in your account.\n2. The workflow fetches the full contact record from HubSpot including lifecycle stage, company, deal value, and any custom properties.\n3. A Code node maps the HubSpot contact data to the correct Klaviyo list and tag based on lifecycle stage -- Lead, MQL, SQL, or Customer.\n4. The contact is created or updated in Klaviyo via API with all mapped properties and the correct list assignment.\n5. The appropriate Klaviyo flow is triggered for that contact based on their lifecycle stage -- for example, a welcome sequence for new leads or an onboarding sequence for new customers.\n6. A confirmation is sent to a Slack channel with the contact name, stage, and which Klaviyo list they were added to.\n7. Every sync is logged to Google Sheets with a timestamp, contact details, stage, and Klaviyo list name.\n\n### Setup steps\n\n- [ ] **HubSpot webhook** -- In HubSpot go to Settings, Integrations, Private Apps or use the Webhooks API. Create a webhook that fires on Contact Created and paste the URL from the Receive HubSpot Contact node.\n- [ ] **HubSpot API key** -- Create a Private App in HubSpot with read access to Contacts. Copy the access token and add it to the Configure Mapping and Settings node.\n- [ ] **Klaviyo API key** -- In Klaviyo go to Account, Settings, API Keys and create a Private API Key with full access. Add it to the Configure Mapping and Settings node.\n- [ ] **Klaviyo list IDs** -- In Klaviyo go to Lists and Segments. Copy the List ID for each list you want to sync to (Lead, MQL, SQL, Customer) and add them to the Settings node.\n- [ ] **Slack** -- Connect your Slack account in Notify Sync Complete and set your channel. Right-click and Disable if unused.\n- [ ] **Google Sheets** -- Create a sheet called Klaviyo Sync Log with columns: Timestamp, Name, Email, Company, HubSpot Stage, Klaviyo List, Status. Connect your Google account in Log Sync to Sheets.\n- [ ] Activate the workflow and create a test contact in HubSpot to verify the sync works end to end.\n\n### Customization\n\nAdd more lifecycle stage mappings in the Map to Klaviyo List node to match your exact HubSpot pipeline. Add a branch to also update existing Klaviyo profiles when a HubSpot contact updates their lifecycle stage. Extend with a Clearbit or Apollo HTTP Request to enrich company data before syncing."
