POST /s/{space_id}/api/agent_builder/conversations/{conversation_id}/_add_events

Auth

Append custom events to a conversation's timeline. The caller must be the owner, a member, or the conversation must be public. Server assigns id, created_at, and actor for each event; the body provides type and data. Only registered custom event types are accepted — built-in lifecycle types are rejected. To learn more about agent conversations, refer to the agent chat documentation.
