How disable old webHook?

[cawa-93]

First I ran the first bot. He worked. Then I changed the token and launched the second bot.
The second bot works fine. But the problem is that the server constantly accepts POST requests for the first bot and returns 401. How can I fix this? How to disable incoming messages from the telegram server from the first bot?

How stop webhook?

I need to manually run TelegramBot.deleteWebHook() on exit?

process.on('exit', () => TelegramBot.deleteWebHook());

When you setup a webhook, Telegram stores your URL. In order to disable the webhook you must call deleteWebHook.

Calling that on exit is a perfect solution.
