Klaviyo integrations that go beyond the standard sync
The standard Shopify–Klaviyo integration is fine, right up until your setup isn't standard: a configurator that never fires 'Added to Cart', a subscription flow in Recharge, a headless storefront Klaviyo can't see, B2B data that should drive segments. I build the developer layer: custom events server-side into Klaviyo, profile properties from your ERP or app, and data feeds your email marketer can actually build flows on.
Sound familiar?
- ✕Your configurator, subscriptions or custom features are invisible to Klaviyo
- ✕You went headless and half your Klaviyo tracking silently died
- ✕Segments are built on guesses because the real data sits in another system
- ✕Ad blockers eat your client-side tracking and your flows misfire
What you get
- ✓Custom Klaviyo events from any source: configurators, subscription portals, apps
- ✓Server-side tracking that ad blockers can't touch
- ✓Full event tracking for headless storefronts (Next.js and others)
- ✓Profile properties synced from ERP, POS or custom databases for sharper segments
- ✓Back-in-stock, price-drop and replenishment triggers on custom product setups
- ✓Clean event naming and documentation your email marketer will thank you for

Frequently asked questions
Isn't the standard Shopify–Klaviyo integration enough?+
For a standard store: usually yes, and then I'll tell you so. It stops being enough when revenue runs through things Klaviyo can't see: configurators, subscriptions, custom checkouts, headless storefronts, B2B pricing. Those need custom events and profile data pushed in via the Klaviyo API.
Do you also build the email flows and templates?+
My focus is the data layer: making sure every event, property and feed your flows need actually arrives in Klaviyo, correctly and reliably. I work alongside your email marketer or agency — they design the flows, I make sure the triggers exist and fire.
Can Klaviyo work with subscription data from Recharge?+
Yes. I've integrated Recharge subscription events (started, skipped, upcoming charge, cancelled) into Klaviyo for lifecycle flows like win-back and dunning. The same pattern works for any subscription or membership system with an API.
