【Important Note: For Merchants' Self-Built Cashier Platforms Only】 After a user completes order payment, they must submit the generated trxId using this interface.⚠️ Note: Failure to submit, submission failure, or incorrect submission information will prevent the order from triggering the callback mechanism, potentially causing subsequent process errors.Please ensure the trxId submission is accurate.
