How to integrate multiple sub-merchants

In the transaction-related API, there is a mid parameter in the request. This parameter is optional. By default, merchants can ignore this parameter. At this time, all transaction requests will be under the default merchant number.

If there is a need to serve multiple sub-merchants after access, it can be distinguished in the mid parameter. Use different values ​​to distinguish different sub-merchants. The specific value range of mid should be confirmed with the ksher operator when entering the network.
