n-Connecting Klaviyo to Your CRM, Ad Platform, or Anything Outside Its Native Integration List
Klaviyo has real, native integrations for the major e-commerce platforms, Shopify, WooCommerce, Magento, and a handful more, plus app-store connectors for tools like Typeform, Yotpo, and Google Ads. For a CRM, a custom-built store, or a platform not on that list, a native integration usually doesn't exist, which is where direct API work takes over.
What the native integration list actually covers
WooCommerce, Shopify, and Magento integrations are deep and well maintained, pulling in full order, product, and customer history so Flows and segments can use it immediately. Smaller or niche platform connectors (Squarespace, Kajabi, Recharge) tend to cover the basics, customer and order sync, without the same depth of event data the bigger platforms get.
The Google Ads integration lets you sync a segment as a custom audience for ad targeting, a genuinely useful native feature for keeping ad spend aligned with your actual customer segments rather than a stale exported list.
A CRM connection, Salesforce or HubSpot, exists as a native app but is narrower than most people expect: it typically syncs profile and basic activity data, not deal stages or pipeline logic, which usually still needs custom work to reach.
Where custom integration work actually starts
A custom-built checkout, a wholesale ordering system, or a storefront platform outside Klaviyo's supported list has no native path in at all. The order, customer, and event data has to reach Klaviyo through its API directly, which, once built, gives you the same depth of data the native Shopify integration gets, just built specifically for your setup instead of a generic one.
The same goes for anything Klaviyo's CRM connectors don't reach: real pipeline stage, a loyalty program running on a separate platform, support ticket history. We sync that in as custom profile properties so Flows and segments can actually use it.
What that looks like built out
Full order and event data from a custom checkout
A storefront outside Klaviyo's native integration list feeds the same depth of purchase and browsing data Shopify stores get, built specifically for how your checkout actually works.
CRM data that reaches past the native connector's limits
Deal stage, pipeline value, or a loyalty tier from your actual CRM lands on the profile as a custom property, so a Flow or segment can act on it, not just the basic activity the native connector syncs.
What system isn't on Klaviyo's native integration list?
If it has an API, we can usually build the connection, no matter how niche the platform.
Running Klaviyo on a storefront or CRM that isn't on its native integration list?
Tell us where your real order, customer, or pipeline data actually lives. We'll build the connection that gets the same depth of data into Klaviyo that a native Shopify store gets. Integrations are one example; n-frames connects whatever your business actually runs.
