Commerce Klaviyo connects Craft Commerce to Klaviyo with a live catalog, reserved ecommerce metrics, and queue-isolated API calls — so marketing automation never blocks checkout.

Live product catalog

Products and variants sync to Klaviyo’s Catalog API as you save them: titles, prices, SKUs, URLs, images, categories, and inventory. Stock changes push lightweight inventory updates that power Klaviyo’s back-in-stock detection. Deletes and unpublishes stay in sync so discontinued items disappear from product blocks and signup flows. A full reindex command (and CP “Sync now”) rebuilds the catalog via bulk jobs after install or recovery.

Ecommerce events that match Klaviyo’s flows

Server-side tracking uses Klaviyo’s own reserved metric names, so pre-built flows work without remapping triggers:

Started Checkout / Updated Cart (with CheckoutURL and OrderId for abandon flows)
Placed Order / Ordered Product
Fulfilled Order / Cancelled Order (mapped to your Commerce statuses)
Refunded Order

Optional onsite JS adds Viewed Product and Added to Cart. A cart restore action lets email links reopen incomplete carts.

Back in stock & lists

Ship a Twig back-in-stock form with a server-side stock guard, clearer API error messages, optional list subscribe after signup, and an inventory reporting threshold to keep high-stock noise out of Klaviyo. Newsletter signup works via a built-in action or an optional Formie binding — always DOI-aware list subscribe, always queued.

Forms, fields & backfill

Optional public identify / track actions for Twig forms (custom events, list subscribe, optional order tracking — off by default). Klaviyo List / Lists field types for entries and users. Historical order sync from the console or Utilities so past orders land in Klaviyo with their original timestamps.

Built for production Craft shops

Every outbound call runs on the queue (dedicated queue component supported)
Env-based API keys for project config
