Klaviyo Integration for Shopify, Adobe Commerce & Custom Stores

Server-side events, custom catalogs and flows that keep working when your storefront is headless or custom, not just a stock Shopify theme.

The default Klaviyo app only tracks what your store surfaces out of the box, whether that is Shopify, Adobe Commerce, or a custom build. The moment you move to a headless storefront, add a custom checkout, run subscriptions, or sell through a B2B portal, the client-side pixel starts missing events. Segments stop matching reality, revenue attribution drifts, and flows fire at the wrong people. We fix that by tracking events server-side, where they cannot be blocked, skipped, or lost, and by feeding Klaviyo a catalog that reflects what you actually sell.

Proven in client projects

Klaviyo is where D2C revenue actually lives. If your attribution looks wrong, it usually is, and it is usually the tracking, not the marketing.

Capabilities

What we build with Klaviyo

The Klaviyo integration work our senior team most often takes on.

Server-side Event Tracking

Viewed product, added to cart, started checkout, and placed order tracked from your server rather than a browser pixel. Ad blockers, iOS privacy settings, and headless storefronts stop being able to quietly delete your data.

Headless & Hydrogen Storefronts

If you have gone headless, the stock Klaviyo app can no longer see most of what your customers do. We wire tracking into your storefront properly so segmentation and attribution keep working, rather than degrading in ways that are hard to notice and expensive to ignore.

Custom Catalog Feeds

Push your real product catalogue into Klaviyo, including the fields your merchandising actually depends on: collections, variants, custom metafields, availability, and pricing. Product blocks and recommendations only work as well as the catalog behind them.

Back-in-stock & Custom Flows

Back-in-stock alerts, price-drop notifications, replenishment reminders, and win-back flows driven by events your store emits rather than events Klaviyo guesses at. If your business has a signal worth acting on, it can be a flow trigger.

Profile & Segment Sync

Push the data you hold elsewhere into Klaviyo profiles: loyalty tier, lifetime value from your ERP, B2B account type, subscription status. Segmentation is only as smart as the properties you give it.

Fixing Broken Attribution

If Klaviyo is reporting revenue that does not match Shopify, the cause is almost always missing or duplicated events rather than a reporting bug. We audit what is actually being sent, find the gap, and close it.

How it works

A Klaviyo integration built to last

The same approach behind every integration we deliver, from the first conversation to the years of maintenance that follow.

01

Scope & map

We define the data, events, responsibilities, source of truth, and failure cases across Klaviyo and the systems around it.

02

Build for failure

We design around real failure modes with appropriate retries, idempotent writes, validation, and reconciliation so a temporary outage does not become silent data loss.

03

Test & reconcile

We test representative data in a safe environment, verify each data path, and reconcile the expected outcomes before go-live.

04

Monitor & maintain

Monitoring and alerting start at launch. Our senior team keeps the project context and remains responsible for changes, incidents, and long-term operation.

What clients say about working with us

“Digital Bird was excellent to work with. After countless attempts with speaking with agencies and other web design contractors, we finally found Jonathan and the team, and what a blessing that was. The project was handled end to end, with clear communication the entire time. We have now engaged Jonathan and the team for on-going website management and work due to how well things turned out. If you are on the fence about which direction to go, I highly recommend just taking a call with Jonathan and the team and seeing what you can achieve together.”

“We have used Jonathan for a number of years to develop and maintain our rather complicated Online Portal and website. Jonathan is always extremely responsive to requests and proactive in ensuring our online presence is safe, presents well and is functional to our customers needs. We would definitely recommend Jonathan for your custom web development needs.”

Nathan Smith East Coast Bullbars
Marketing Manager, East Coast Bullbars

“Digital Bird is my first pick for delivering web projects on time, on budget and to the brief — every time.

Beyond being a delight to work with, Jonathan Bird is that rare breed of developer who is both masterful on the tools (an absolute Laravel whizz!) while also being adept at engaging the client in UX-thinking, to which he applies expert insights, gained through years of experience, to help further improve the end design for the target user’s experience.

This powerful combination of skills means that 4 years on and a variety of projects later (from search directories to corporate website developments), Digital Bird firmly remains my first pick for developer.”

Emma Keller Brisbane South PHN
Communications Manager, Brisbane South PHN

“We’ve been working with Jonathan Bird for our website maintenance, and he has been nothing short of exceptional. Jonathan consistently goes above and beyond, responding quickly whenever we need help and resolving issues with impressive turnaround time. His communication is clear and thorough — he always explains what the problem was, how he fixed it, and provides helpful recommendations for long-term solutions. It’s rare to find someone this reliable and proactive. Highly recommend!”

“Digital Bird has had a huge influence on our business providing many solutions besides just a fantastic reliable website. Jonathan is great to work with and has a solution to every challenge. Jonathan also has the ability to “dumb it down” and provide timely advice and assistance if something goes astray. With Jonathan we have in excess of 99% uptime on all three websites.”

“Velg Training has had an excellent experience working with Digital Bird. Jonathan has supported us with a complex Laravel/PHP website and has brought a rare mix of deep technical knowledge, practical problem solving, and clear communication.

He has assisted with major infrastructure and platform work across AWS, Laravel Forge, Cloudflare, Redis, S3, Sentry, PayWay, Mailchimp/Mandrill and related integrations. His work has included setting up and migrating infrastructure, improving performance, resolving production issues, monitoring errors, modernising legacy code, and strengthening the reliability of key business workflows such as checkout, invoicing, membership exports, PDF generation, transactional emails and background queues.

What stands out most is that Jonathan does not just “fix the ticket”. He investigates properly, explains the cause in plain language, and looks for the right long-term solution rather than quick patches. He has helped us move away from fragile legacy processes, improve automated testing, reduce errors, improve email reliability, address performance bottlenecks, and make the platform easier to maintain into the future.

He is responsive, thorough and highly professional, with an obvious understanding of business-critical websites and custom web applications. We would happily recommend Jonathan to any organisation needing a skilled, reliable and commercially minded Laravel/PHP web developer.”

Straight advice

The simplest reliable integration usually wins.

The right design depends on volume, timing, ownership and what must happen when either system is unavailable.

Not every sync needs to be real-time

Scheduled or event-driven updates can be safer, cheaper and easier to recover.

Choose a source of truth

Each field and business rule needs one accountable owner across the connected systems.

Design the failure path

Retries, logs, alerts and reconciliation are part of the integration—not optional support work.

The Difference

Klaviyo that still works after you customise your store.

The standard Klaviyo install is genuinely good, right up until your store stops being standard. Custom checkouts, headless storefronts, subscriptions, and B2B portals all punch holes in client-side tracking. Most agencies do not notice, because the dashboard still shows numbers. They are just the wrong numbers.

A common shortcut

Installs the app, ticks the box.

  • Installs the Klaviyo app, confirms the dashboard shows numbers, and calls the integration done.

  • Relies on client-side pixels, so ad blockers, privacy settings, and headless storefronts silently drop events.

  • Flows are built on whatever properties the default app happens to sync.

Our senior-team model

Tracks what actually happened.

  • Checks that the numbers are right. Klaviyo revenue should reconcile against Shopify, and if it does not, that is a tracking bug worth finding.

  • Tracks the important events server-side, where they cannot be blocked or lost, so your segments reflect reality.

  • Profiles are enriched with the data that actually matters to you: lifetime value from the ERP, loyalty tier, account type, subscription state.

FAQ

Common Klaviyo Integration Questions

Common questions our team is asked about integrating Klaviyo.
It can, but not out of the box in the way people assume. The default integration leans on Shopify's own storefront to fire tracking events, and a headless storefront is not that. Without server-side tracking you typically keep order data and lose most browsing behaviour, which quietly guts your segmentation and abandoned-browse flows. The fix is to emit events server-side from your storefront and your backend, which is exactly what we build.
Nine times out of ten it is missing or duplicated events rather than a Klaviyo reporting problem. Common causes: client-side events blocked by privacy tooling, a custom checkout that never fires the standard events, orders created through a channel the integration does not watch, or the same order being tracked twice through two different paths. It is diagnosable. We audit what is actually being sent, compare it against Shopify, and close the gap.
Yes, and this is where it gets genuinely powerful. Any signal your business cares about can become an event and therefore a flow trigger: a quote requested, a subscription paused, a warranty registered, a trade account approved, a product back in stock in the customer's size. If your system knows it, Klaviyo can act on it.
Yes. Klaviyo's catalog can be fed from your real product data rather than only what the default sync picks up, including variants, metafields, collections, and availability. This matters if your product recommendations or dynamic product blocks currently look thin or show things that are out of stock.
For eCommerce, Klaviyo, and it is not especially close. Klaviyo is built around commerce events and product data, so segmentation, flows, and revenue attribution are native rather than bolted on. Mailchimp is a decent general-purpose email tool that happens to have eCommerce features. If you are running a store and email is a meaningful revenue channel, Klaviyo earns its higher price.
