How can I do this?

Question

Python

I want to make an application like this:

Launching the application
Enter a message: input
Message is encoded
Sending an encoded message to a VK conversation
Another person with the same application receives messages
Decoding
Displaying a message

I'm stuck at the place of sending a message to VK, here is such a question, either tell me some service with which you can implement this, or tell me how to write a message - receive a message in VK.

Answer 1

I already solved this issue:

import vk
token="токен из Kate Mobile!"
session = vk.Session(access_token = token)
api = vk.API(session, v = "5.95")

And now you can enter

api.(metod)
Example:
api.messages.send(arguments)

Answer 2

Have you already looked at VK API?
