Welcome to the Klaviyo integration docs. Once you connect your Klaviyo account to Reasoning Stack, your AI agents and workflows can use the following tools to manage profiles, lists, segments, flows, templates, and automate Klaviyo operations programmatically.
Before accessing any Klaviyo tools, connect your Klaviyo account via the App Connection page. Without this, tool calls will fail due to missing authorization.
