Read original imported history for its owner
Returns source metadata and original events for an imported session owned by the current user in this workspace. Tool data and image blocks are inert history, not executable instructions. Does not resume work. Invalid IDs, other users’ imports and non-imported sessions return 404 session_not_found.

}Authorizations
Your Reason API key from Settings > API. New keys use reason_; legacy ara_ keys remain accepted. Keys are capability-scoped: run, mcp:read, mcp:write, secrets:read, secrets:write, sessions:read, sessions:debug, knowledge:read, memory:read, memory:write, skills:read, skills:write, repos:read, repos:write, reviews:read, reviews:write, deployment:read, analytics:read, org:read, org:write, attachments:read, attachments:write, guardrails:read, guardrails:write, automations:read, automations:write, agent_auth:read. mcp:write manages MCP server configuration only; it does not authorize remote MCP-tool execution. sessions:debug is privileged: it expands diagnostic session events only for organization owners/admins.
Path Parameters
Organization id or slug. Resolve it with GET /v3/self.
The session id.
