Sending messages in Viber at the user's request?

Question

Viber

It is necessary for a specific user to send updates from the site. There will be three types of such announcements. Accordingly, the user must have three chats, which will receive updates. How can this be implemented? I did not find anything similar in the Viber API, there is only mailing from a public account. In addition, there will be many of these users.

Answer 1

1) Make a bot (public account)
2) Ask your users to start a chat with it
3) Save their viber-id
4) When necessary, send ads to these id
You can make three bots, the meaning does not change.

The user started a dialogue with the bot, what's next?

@app.route('/', methods=['POST'])
def incoming():
    if isinstance(viber_request, ViberSubscribedRequest):
        user_id = viber_request.sender.id
        # Здесь добавляйте user_id в базу данных

If something is not clear, write in the comments

In addition, there will be many of these users.
