This is cool. I wish Signal had a bot API like telegram's.
It is always preferable to use WhatsApp to contact a business than calling up.
And unlike Telegram, for a WhatsApp bot you need to apply with a bunch of paperwork. If you're an SMB, you got little chances of ever getting access. They'll tell you to go with their Technology Partners and make a chatbot with these other BigTech companies like Freshworks, etc.
I run my agent over Signal with this, the only difference with Telegram is you need to host this. Other than that, it's great.
Setup was quick enough but it needs a real phone number once during setup which is kind of a hassle. still better than using telegram which has no encryption for the bot backend so the devs can read everything you write
No one talking about security, but I cannot argue that Telegram has by far the most powerful bot platform. People do with it great stuff.
For private chats I use WhatsApp yes. But telegram has its uses. Why does it matter that telegram can see your local bus times that are published online anyway?
Telegram is great because it has bots, etc. but Signal is great because they have one core focus and they don't complicate their infrastructure or codebase by adding things that aren't what people want from Signal.
There's nothing wrong with having two messaging applications; let Telegram be the bot and automation platform of choice and let Signal focus on being a secure and reliable messaging solution.
