Klaviyo Magento Integration Guide (2026)

Quick answer: To connect Klaviyo to Magento (Adobe Commerce), install the Klaviyo extension on your Magento 2 store and connect it with your Klaviyo API keys. It syncs customers, orders, products, and checkout events, and enables onsite tracking for browse and cart flows. Then build a signup form and turn on the core flows. Magento setup is a bit more technical than Shopify, so allow time for configuration.

Key takeaways

• Install the Klaviyo extension for Magento 2 and connect via API keys.
• It syncs customers, orders, products, and checkout events.
• Magento setup is more technical — onsite tracking and catalog sync need care.
• Build the same core flows once data is flowing.

Running Magento (Adobe Commerce) and want Klaviyo? Here’s how to connect them properly. This pairs with our how to set up Klaviyo guide and integrations overview.

Install and connect

Install the official Klaviyo extension for Magento 2 (via Composer or the Magento Marketplace), then connect it using your Klaviyo public and private API keys in the extension configuration. On Magento, give the configuration extra attention — caching, indexers, and cron need to be healthy for syncing and tracking to work reliably.

What data syncs

Once connected, Magento pushes the data Klaviyo needs:

• Customer profiles — for segmentation and personalization.
• Orders & revenue — purchase history powering segments and LTV.
• Checkout & cart events — triggers for abandoned cart and browse flows.
• Product catalog — for dynamic blocks and recommendations.

Onsite tracking and forms

For browse abandonment and active-on-site tracking, ensure the Klaviyo onsite snippet fires on your storefront — confirm it loads given Magento’s full-page caching. Then build a signup form in Klaviyo to grow your list and feed the welcome flow.

Essential flows for Magento

The same core automations apply:

• Welcome series — greets new subscribers.
• Abandoned cart — recovers Magento checkouts.
• Browse abandonment — needs onsite tracking active.
• Post-purchase — onboards buyers and cross-sells.

Build these from templates with conditional splits — see the complete flows guide.

Troubleshooting

• Events not firing: check that cron is running, indexers are up to date, and the snippet isn’t blocked by full-page cache.
• Catalog not syncing: confirm product feed configuration and re-index.
• Sync delays: Magento sync can lag on large catalogs — verify cron frequency.

Because Magento is self-hosted and more complex than SaaS platforms, a clean configuration is worth getting right the first time.

Frequently asked questions

Does Klaviyo work with Magento 2 / Adobe Commerce?

Yes. Klaviyo has an official extension for Magento 2 (Adobe Commerce) that syncs customers, orders, products, and events, and enables the same core flows as other platforms. Setup is more technical than SaaS platforms.

Why isn’t my Magento data syncing to Klaviyo?

Usually a Magento infrastructure issue — cron not running, indexers out of date, full-page cache blocking the onsite snippet, or a misconfigured product feed. Verify these before assuming the integration is at fault.
