How to check if a person is a member of a community (VK API, LONGPOLL)?

Question

Python

We need a python code to check if a person is in the community, I think it will be like this:
we get a message, if the id is in the conversation, then the code goes further, and if not: you are not subscribed, and so on.
How do I implement this? (PYTHON 3.7)

Answer 1

then the code goes further, and if not: you are not signed, and so on.

Firstly, if you do this, the community will be blocked.
Secondly, you need a code - write or pay someone who writes. We do not write code here, but we can suggest what I will do. Longpull returns the identifier of the person who sent the message (user_id / from_id). Next, you need to form and send a new request to the groups.isMember API method .
