List Messages

Read a conversation thread oldest-first. Unlike the other v1 chat lists this one is cursor-paginated: omit before for the latest page, then pass meta.before from each response to walk backwards until meta.hasMore is false. Deleted messages are returned with a null content and no attachments rather than being omitted, so the thread's shape is preserved. Every operation is scoped by the required workspaceId. A workspace-scoped API key that names any other workspace is refused with 403 before any query runs, so a workspace key can only ever reach its own workspace.

GET/api/v1/chat/conversations/{conversationId}/messages

Authorization

apiKey
X-API-Key<token>

Your Studio API key, personal or workspace-scoped. Generate one under Settings, then API Keys. Operations that reject workspace keys say so in their own description.
