# sendSubscriptionKlaviyoEvent

Sends a bespoke Klaviyo event for one subscription, independently of the project's configured customer communication channel

The subscription identifies the Klaviyo profile and `properties` supplies the event-specific JSON object. String values can use the standard Firmhouse Liquid roots and filters. Klaviyo must be connected and enabled for the project.
