How to create a telegram API link, by clicking on which I will receive messages in Json format from someone else's channel?

Question

API

I need to generate an API link by clicking on which I will receive posts / messages from the telegram channel in Json format.

It is necessary that I can specify in the link id the channel (I recognize it with the help of @getidsbot), from where to get messages. The number of messages to display.

The key token was created via @BotFather. I did https://api.telegram .org/ bot11111111:aaaaAAAA/getUpdates?chat_id=-1000000000 using this method and it doesn't work. Gives messages of the bot itself, but it is necessary from the specified telegram channel.

There is also a getChatHistory method, which also failed to substitute it.
Maybe you need to generate a current key from your own profile, if so, how?

Answer 1

Telegram Bot API does not allow you to receive updates from other people's channels (that is, in which the bot is not a member).
You can use the MTProto API to read message history from any public channels .
It will not be possible to generate a link to the required API request, because MTProto is a different binary cryptographic protocol than HTTP, but you can use, for example, the Pyrogram (Python) library to interact with it.
