How to send messages to a private telegram channel through a bot (PyTelegrambotAPI)?

Question

Python

There is a telegram bot for ordering food. At the moment when the order is fully formed, the bot should send a message with the content of the order to the private tg-channel (namely, to the private one, because the public one has a link to the channel like "@channelname"). Maybe someone faced a similar problem? The bot has been added to the channel as an administrator.

Answer 1

Just like in another channel/group/chat - by ID

Answer 2

I found a solution to get the channel id, you need to make the private channel public, assign it a nickname, then send any message to the channel via the bot's api:
https://api.telegram.org/botXXX:YYY/sendMessage?ch... , where XXX :YYY - your bot's token, channelname - link to the channel. The received response will contain the chat ID, save it for yourself and you can change the channel type back to private.
