Klaviyo and Shopify already have something most platforms can't claim: a true bidirectional integration. Your Shopify store data flows into Klaviyo to power your marketing. Your Klaviyo performance data flows back into Shopify so you can act on it. It's the kind of deep, two-way connection that makes the combined stack more powerful than either platform alone.
Today, that integration gets even deeper.
Klaviyo is one of the first partners to launch a Sidekick app extension; the new feature that lets merchants ask Sidekick questions about their apps directly inside the Shopify Admin.
What Sidekick Extensions actually does
Sidekick is Shopify's AI assistant for merchants. With Sidekick app extensions now generally available, apps like Klaviyo can surface their data conversationally inside Sidekick. So, instead of navigating between platforms to understand what your marketing is doing, you just ask Sidekick.
Ask it things like:
- "How did my welcome flow perform this week?"
- "What's the revenue from my last campaign?"
- "Show me my top-performing segments."
You can ask Sidekick about your campaigns, flows, segments, and revenue attribution and it calls Klaviyo's tools in the background and brings the answer back to you, right in context.

Why this matters for Shopify merchants
Klaviyo and Shopify are already the go-to combination for the world's fastest-growing B2C brands. But even with tight platform integration, the data has lived in two separate places. Sidekick app extensions closes that gap.
This is what AI-forward partnership looks like in practice: not just connecting platforms, but making the information flow effortlessly between them at the moment you need it.
What's available today
Klaviyo’s Sidekick app extension gives merchants conversational access to:
- Campaigns: performance, send stats, revenue attribution
- Flows: triggered automation performance and analytics
- Segments: subscriber lists and growth data
- Analytics: key metrics across your Klaviyo account
At launch, Sidekick can surface your Klaviyo data and answer questions about it.
How to get started
If you're using Klaviyo and Shopify together, the extension is available now through the Shopify App Store. Open Sidekick in your Shopify Admin and start asking questions about your Klaviyo data. That's it.
The Shopify + Klaviyo stack has always been about giving merchants the best tools to build and grow. Sidekick app extensions is one more step in that direction.
