Wechat push information function

You can use the advanced mass sending interface for development, but you should pay attention to the following matters:

1. For the time being, this interface is only provided for service numbers that have passed WeChat authentication.

2. Although the maximum number of daily calls by developers using the advanced group sending interface is 100, users can only receive 4 messages per month. Please test it carefully.

3. Users can only receive four mass messages every month, no matter on the public platform website or using the mass communication interface, and more than four mass messages will not be sent to users.

4. The official WeChat account with WeChat payment authority can be added to the external chain using the a> tag.
