Yes their API is one of the best. A simple curl request is enough to send a message and it has been so useful (sentry, uptime, door bell notifications(1), etc).
As a result, you have a large set of very good clients for pretty much all platforms.
Imagine if the FLOSS darlings like Signal would make something as amazing as this - a library any plaform (from RPi, watches, etc.) to implement the best possible secure client that fits the user.
I didn't enjoy using it without a third party library [1].
Sending a single message is easy, but using the rest of telegram's features is "meh" when using pure API calls.
If you want to see a well designed API, you should take a look at FTX or Stripe. I love those two :)
hmmm ... could I participate fully on Telegram without ever installing the app anywhere ?
That would be compelling ...
I’m not sure the signup is available without the app, that’s the only thing.
