Why messages only come to one Telegram bot instance?

Question

Messengers

Created a bot in Telegram (via Botfather). I send messages to it from the computer with the following line:

https://api.telegram.org/bot<Token>/sendMessage?chat_id=<ChatID>&text=Hello.

Messages come to your phone where the bot was created, but there are no messages to other phones that have added a bot to themselves. Why and how to make messages visible to everyone who has a bot added?

Answer 1

Understood. For those who are interested:
1. Create a bot through Botfather, press START. During the creation process, BotFather will issue a unique Token.
2. In the browser, execute

https://api.telegram.org/bot[ТОКЕН_БОТА]/getUpdates

, find the chat id.
3. The bot can already receive messages

https://api.telegram.org/bot[ТОКЕН_БОТА]/sendMessage?chat_id=[ChatID]&text=Hello.

If we want to send these messages to a group of people:
4. Create a group (public), add a bot there.
5. Open the link in the browser:

https://api.telegram.org/bot[ТОКЕН_БОТА]/[email protected][USERNAME_ГРУППЫ]&text=тест

, we get the group id (it is negative).
6. Now you can send messages to the group:

https://api.telegram.org/bot[ТОКЕН_БОТА]/[email protected][ID_КАНАЛА]&text=тест

7. The group can be made private.

Why and how to make messages visible to everyone who has a bot added?

Maybe you need to create a group and add a bot there that will send messages to the chat. And these messages will be seen by everyone who has this chat.
