What this integration does
The Klaviyo connector in VeloCMS listens for two events. On afterMemberSignup, it imports or updates a Klaviyo profile for the new member and, if you configure a list ID, subscribes that profile to the list. On afterOrderCreate, it sends a Placed Order event to Klaviyo with the order value and a unique event ID so Klaviyo can deduplicate replays. Both handlers are fail-soft: a Klaviyo API error is logged but never blocks the member signup or order webhook. It is a one-way push from VeloCMS to Klaviyo — your email strategy runs in Klaviyo while VeloCMS feeds it the right signals.
