Modify Customs Declaration Info API

Latest update time：2022.08.04 Release notes

This API allows merchants to modify additional order information.

Tips：

This API will generate new data for declaration while invalidating the old application data. There is no need to call the re-push API. This API can be used to modify only the merchant's customs registration No., tariff, sub-order amount, logistics fee, and product price. If the merchant's customs registration No. is modified, the new registration No. and registered name of the merchant will be obtained for declaration again.
