# createDiscussion

> Create a new discussion. Supersedes createThreadDiscussion and additionally supports Sidekick
AGENT_SESSION discussions (which can be started without a thread). For Slack, Email, and Cursor
discussion types, a threadId is required. For AGENT_SESSION discussions, threadId is optional and
the discussion may be associated with a source entity (company, tenant, etc.) or page instead.
