Merchant Daily Posting Statement

Cancel Pending Orders

This interface is exclusively available for hybrid cloud SaaS + merchants. To use it, the merchant's API must be confirmed via callback. The callback URL is: https://xxxx.xxxx.xxx/nofity/transferToMerchantAuthCheck. Merchants need to provide the callback domain https://xxxx.xxxx.xxx to the platform for configuration. The callback method is fixed as: /nofity/transferToMerchantAuthCheck. After receiving the callback, the merchant must perform signature verification. The verification method is the same as that used for requesting this interface (if the request uses MD5, the callback should also use MD5 rules for verification; if the request uses RSA, the callback should also use RSA for verification).

Payment needs to call back

Deduct the user's assets to the open platform account and call back the merchant API for confirmation

Either the UID or OpenID of the payee must exist, and if both are present, the OpenID takes precedence.
