Klaviyo data reference

This article describes the profile data Faslet syncs to Klaviyo and explains what each property means.

What syncs to Klaviyo

Faslet syncs profile properties to existing Klaviyo profiles. These values are updated after a shopper completes the Faslet popup sizing flow and Faslet can resolve the correct Klaviyo profile for that shopper.
