## Notes for agents

- Errors are proprietary result codes (T/R/A/C/N/D prefixes + screen-specific families), paired with a Korean message; see errors/payple-response-codes.yml.
- Idempotency: duplicate payments are rejected by merchant order id (PCD_PAY_OID).
- Async result delivery is a merchant callback URL (PCD_RST_URL); re-confirm via the approval/confirm endpoint before fulfilling.
