The complete guide

Understanding CustomFit.ai integrations

CustomFit.ai integrations connect your ecommerce platform, analytics, messaging, checkout, CDP, and ad tools — Shopify, WooCommerce, GA4, Segment, Klaviyo, Razorpay, Meta, and 40+ more — so first-party data flows in and tested, personalized experiences flow out, with no glue code.

A connected stack means one source of truth: an audience built from analytics or your CDP can power tests and personalization, while experiment exposures and conversions sync back to the tools your team already uses. Every connector authorizes in minutes via OAuth or an API key.

All integrations are two-way, configurable, and audit-logged, with edge evaluation that adds no latency. Whether you need an ecommerce platform, an analytics destination, or a checkout signal, the data loop stays clean and real-time.

Are integrations two-way?

Yes. Data flows into CustomFit to build audiences and target experiences, and exposures plus conversions flow back to the connected tool.

How long does setup take?

Most connectors authorize in minutes via OAuth or an API key, with no engineering work required.

How quickly can I get started?

Most teams install in minutes via a single script tag or the Shopify app and ship their first experiment the same week.

Do I need a developer to use CustomFit.ai?

No. Marketers build experiments and personalized experiences in a no-code visual editor; developers can use the API and SDKs when they want deeper control.

Don’t see my tool?

We add connectors regularly and offer a webhook + API for anything custom. Ask us.

Don't rip and replace. Just connect.

CustomFit slots into your existing stack — usually live in an afternoon.
