kb_fast_account__accounts__transaction_history__search

Read-only

REQUIRES prior kb_fast_account__session__login call with same account_link_id. Search transaction history for one registered KB Kookmin Bank fast-account using the existing provider session. Files: a document generated from this result, as Excel (xlsx) only when requested in output_formats, listed in artifacts[] of the result with a download_url that works for 15 minutes; each file is kept for 7 days. If a link has expired, call xdata__job__result with the job_id from the result for fresh links.
