Official account template message push

1. First of all, the official account and the mini program need to be under the same subject
2. You need to apply for the template you need in the official account "Advertisement and Service" → "Template Message"
3. You need to get the appid, appsecret and IP whitelist corresponding to the configuration server in the official account "Settings and Development" → "Basic Configuration"
4. Secondly, the push requires the pusher to pay attention to the official account and get the user's openid to push
5. Finally, if you click on the template message to enter the applet, you also need to provide the appid and path information of the applet.
   The above is the general process of public account push.
