Do I need to generate RSA signatures manually for each API call?

No! Simply provide your App Private Key in PKCS1 or PKCS8 format. The engine handles all RSA-SHA256 signing, timestamping, and parameter encoding under the hood automatically on every request — you never touch signature logic directly.

Can I process partial refunds specifying only a fraction of the original order amount?

Yes! The `refund_trade` tool supports both full and partial refunds. Specify the original trade number, the refund amount, and a reason string. The engine will dispatch the correctly signed request and return the settlement confirmation with a unique refund ID for tracking.

Is there any risk of accidental payments or unauthorized fund transfers through this integration?

Every transactional action requires explicit parameters — trade amounts, recipient accounts, and refund values must all be specified deliberately. The RSA2 signature layer ensures that no request can be forged or replayed. Additionally, all operations are scoped to your registered App ID and sandbox/production environment.
