The Klaviyo destination now supports API version 2026-04-15.
New connections use API version 2026-04-15 by default, while existing connections keep their saved API version until you change it via the API Version to use destination setting. API version 2024-10-15 remains selectable but is deprecated.
Important considerations
For API version 2026-04-15, the selected Consent channel must match an identifier in subscription events: Email consent requires an email identifier and SMS consent requires a phone identifier. The event fails if no selected channel can be resolved.
Resources
See the Klaviyo Setup Guide for more information on selecting an API version and configuring consent channels.
