Create Payout BeneficiaryFINMO_CREATE_PAYOUT_BENEFICIARY
Create a real payout beneficiary in the connected Finmo production account. This does not move money, but Finmo stores the supplied sensitive bank, proxy, identity, and contact data and the record can enable later payouts. First call FINMO_LIST_PAYOUT_METHODS and FINMO_GET_PAYOUT_METHOD_REQUIREMENTS, then provide only the selected method's required destination and identity fields. A newly created beneficiary may take 24 hours to activate. Reuse idempotency_key only for an identical retry.
