Telegram.Bot VS telegram-bot-api

Studying guides and the API documentation. Actually, why are you even asking us, just ask ChatGPT. People obsess too much about how you can break or the fact that it will make up shit when discussing historical facts, but for everything else it's actually amazing. Like a friend who knows a little bit of everything and you just ask them if you don't know how to google the answer.

Telegram.Bot nuget documentation

Is not that hard, they have amazing documentation about it: https://core.telegram.org/bots

You can make authorization via Telegram another way. It works. But today we want to do the classic OAuth Authorization. Before you begin, you need to create a Telegram bot and obtain your bot token. You can do this in @BotFather in Telegram. For more information on initiating a bot, read the Telegram Bot API documentation: https://core.telegram.org/bots

Absolutely possible. Here's the github page to the Telegram bot API. You would just need to check for incoming messages, check the body of the message for a word or phrase, and then send a message back with a photo or gif and an encouraging message.

Creating a Telegram bot is fun: there's no website, no sign up, no forms — you just use a... bot. Yes, a bot that creates bots. It's called the BotFather 😂

Telegram has a bot API server that provides API to control the bots and get updates. Their own instance has some restrictions like you cannot download files bigger than 20MB. So, using a self hosted bot API server, you can overcome those limits.
