3 I know 12 I'm not sure that Huanxin has a special ID. My approach is to use a unique identifier such as the user's ID as the Huanxin registration ID when the server gives the user registration data, so that it can be associated.

It’s all in Huanxin, and the background can call and query through the interface. The pictures and texts are like this.
There is a frequency limit for the background interface call
