Pure Python barebone wrapper that only provides access to /getUpdates (by constant polling) and /sendMessage Telegram Bot REST APIs.
The entire setup requires setting up a Telegram Bot (easy step-by-step guide here), as well as an Internet-connected machine hosting this script.
Install python3 and pip3, in the system hosting the script (I used a Raspberry Pi Zero, Python 3.7):
sudo apt-get install python3
Clone to your local directory:
git clone https://github.com/ohsyln/barebone-telegram-api
cd barebone-telegram-api
Edit BOT_API_KEY in demo.py with a text editor:
BOT_API_KEY = "<YOUR TELEGRAM BOT API KEY HERE>"
Run script, which takes in user input from Telegram Bot (via /getUpdates) and sends the JSON-structured message back to the user (via /sendMessage).
python3 demo.py
