Get purpose codes
Purpose codes accepted for a payout from this Sender to a bank Beneficiary. Every order needs a purpose_code that is valid for its Sender and Beneficiary. Always fetch the list and use the code exactly as returned; do not hard-code it. Names are returned in Chinese.
OTHR (“other”) requires an extra description that orders can’t carry yet. Don’t offer it.
