private-cartesia-voice-clones.{userId}

Channel events: 1

Every event has its own anchor, a full payload table with descriptions and enums, and a sample shape. Names are shown in Laravel Echo notation — with the leading dot.

.voice_clone.updated

Echo: .voice_clone.updated · pusher-js: voice_clone.updated

A Cartesia voice clone was created or changed status (pending → cloning → ready or failed; archived after deletion). voice_id appears only once the clone is ready — put it into tts_settings.voice_id of a Cartesia template.
