Hi Recently I came to know about wechat mini program but as material is very less so I am unable to differentiate the official account and mini program.
I came to know that wechat mini doesnt have push notification but client wants to send the push notification from mini program.
The requirement is that mini program URL will be configured in official menu URL so when User will click to the link wechat will redirect to mini porgram when user clicks on any action then an API call should happen back to the offical program and send the push notification using union ID. Is my assumption right and is it possible?
I think you maybe need the customer service message function,here is the article from the official sites: customer service message
