The applet development sends a message to the designated WeChat.

You can use the message push function in applet development to send information to the designated WeChat through the API provided by the official WeChat.

First of all, you need to register a developer account in the background of the applet and get the corresponding developer credentials and permissions.

Then use the developer credentials and permissions to send messages to the designated WeChat through the API. The specific steps include:

1. Build message content, including text, pictures, links, etc.

2. Get the OpenID of the target WeChat user, which is the voucher used to uniquely identify the user.

3. Call the message push API and send the message content and OpenID of the target user as parameters.

4. Process the response result of API to confirm whether the message was sent successfully.

It should be noted that the use of applet development to send messages needs to meet some conditions, such as the need for users to subscribe to the official WeChat account and authorize relevant permissions. For specific operation steps and code examples, please refer to the official WeChat document, which contains detailed development guide and sample code.
