hometax__certificate__listREQUIRES prior hometax__session__login call with same account_link_id. List certificate applications already filed at Hometax (민원증명 발급 목록) with their receipt ids (cvaId, rcatNo). Read-only. Without strt_dt/end_dt only the last 3 days are returned, so an empty result does not mean the taxpayer has no certificates — widen the period to look further back. Send both dates or neither. One call covers at most one calendar month (strt_dt no earlier than end_dt minus one month); a longer period is refused, because the institution returns an empty list for it instead of an error — split it into monthly calls. For an authenticated call, generate and save request_idempotency_key before the first request. Reuse it with the same arguments only to recover that request after a lost response; use a new key for a new execution. Without it, calling again remains a new request. This optional key is not available to anonymous taste calls. Keep any provider-specific idempotency_key unchanged; it is a different field. 호출마다 토큰 1소진
