telegram-bot-api VS signal-cli

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.

It's done via bots, which let you add clickable options to posts. Here's an FAQ on bots: https://core.telegram.org/bots

Not official but this works darn well: https://github.com/AsamK/signal-cli

If you want one for just personal use; this works well: https://github.com/AsamK/signal-cli

Just sign up with a Twilio number (using voice call) and you can make your own bot.

Yes, using the signal-cli program. It has a built in JSON RPC API that can be used to develop application integrations

Last commit was 2 days ago so it should still work: https://github.com/AsamK/signal-cli

Sorry to hear. Then the cheap backup may be a Signal CLI forwarded over to mqtt CLI

build, install and configure/register signal-cli. The code snippet below assumes you are running it in multi-account mode, but I'll leave a comment where it matters

No official API that is public from what I can tell, but appears this works https://github.com/AsamK/signal-cli
