Klaviyo

Klaviyo support focuses on profiles and campaign reads. Vorlek hides API revision details and normalizes Klaviyo's status vocabulary for agents.

Connection setup

Create a Klaviyo private API key starting with pk_.
Grant scopes for profiles, campaigns, and templates according to the tools you plan to call.
Connect with vorlek connect klaviyo --api-key pk_xxxxx or through the dashboard.
Run get_connection_status before relying on the connection in an agent workflow.

Gotchas

Vorlek pins Klaviyo API revision 2026-04-15 for launch behavior.
Klaviyo accepts arbitrary profile properties, so fields_auto_created is always empty even when new properties land.
Klaviyo campaign statuses are Title Case natively. Vorlek accepts and returns lowercase draft, scheduled, sent, and all.
Transactional email is flow-triggered and asynchronous, so send_transactional returns TOOL_NOT_SUPPORTED.
