Build a chrome extension for whatsapp web

Develop or modify a chrome extension for whatsapp web.

For exampleif any message receive on whatsapp web then the extension will post the message to a remote server like

https://example.com/message.php

Post like this

{
“sender”: “A person’s name or number who is sending you the message”,
“message”: “Incoming message”
}

This is my first requerment.

2nd is.

If i request to send a message to a number from remote server to the extension then you extension help you to do this.
For example i request

{
“sender”: “A person’s name or number”,
“message”: “A message”
}

If the request method not possible to do then you can use mysql database to send a message. Then if i crate a record into the database then the extension will check and send the message.
Then your extension will send the message to a number.
