# List fiat transaction statuses

Retrieves fiat transaction status objects for the calling platform. Defaults: when `start_date`/`end_date` are omitted, the last day of transactions is returned; when `page`/`size` are omitted, the first 200 transactions are returned; omitting `participant` or `status` removes the respective filter.
