Sync new WooCommerce customers to HubSpot and Klaviyo automatically

Build a code workflow that mirrors every new WooCommerce customer into HubSpot CRM and Klaviyo so sales follow-up and email marketing can start immediately.

Trigger: a WooCommerce outgoing webhook on the customer.created event. The webhook payload includes the customer's id, email, first_name, last_name, date_created, and billing object (city, country, phone).

Step 1: Call HubSpot Create Contact with the WooCommerce customer's email, first name, and last name, and set the lifecycle stage property to 'lead'. If HubSpot returns a 409 conflict because the contact already exists by email, treat it as success and continue.

Step 2: Call Klaviyo Create or Update Profile (Upsert) using the same email as the matching identifier. Pass first name and last name as profile attributes, and include the WooCommerce signup date, billing city, and billing country as profile properties so segments and flows can use them. Capture the returned Klaviyo profile id.

Step 3: Call Klaviyo Subscribe Profiles (Bulk) to add the new profile to a configurable marketing list (expose the list id as a workflow input). Subscribe to email marketing with a custom_source of 'WooCommerce signup'.

Inputs the workflow should expose: the HubSpot lifecycle stage (default 'lead'), the Klaviyo list id, and a toggle for whether to subscribe to email, SMS, or both.

This is a deterministic CRUD pipeline with no reasoning required, so build it as a fixed code workflow with three discrete nodes in sequence, not an agent. Add basic error handling on each node so a transient failure in one downstream service does not block the others.

The name of the Klaviyo list you want new customers added to.

How can I customize it?

Frequently asked questions

Will existing customers in HubSpot or Klaviyo get duplicated?

No. Both updates match on email address. If the customer already exists in HubSpot or Klaviyo, their record is updated instead of duplicated.

How fast does this run after a new customer signs up?

Within seconds. WooCommerce sends a signal the moment a customer is created, and the workflow runs immediately from that.

Do I need a paid HubSpot or Klaviyo plan?

No. Contact creation in HubSpot and profile management in Klaviyo are available on all plans, including the free tiers.

Can I add the customer to more than one Klaviyo list?

Yes. The list is configurable, and you can extend the workflow to subscribe new signups to multiple lists at once.

What happens if HubSpot or Klaviyo is down when a signup comes in?

The workflow retries failed steps automatically, so a brief outage will not cause you to lose customers from your CRM or marketing list.
