Identity Information Verification API

Latest update time：2020.06.02 Release notes

This API allows merchants to upload the purchaser and payer identity information which will be re-verified by WeChat Pay, and the verification result will be returned for the merchants to correct any wrong information in the declared order

Tips：

WeChat Pay can only push the payer information registered on the system to the customs, regardless of whether the identity information is verified as consistent.
This API can be called only for declared orders.
