I used botfather to create a telegram bot. I used the generated bot token in my python code. I also used python-telegram-bot package to handle my codes.
The problem was the file size limitation because of the bot-telegram-api and its http-interface provided by telegram. The solution I found is this: Using a Local Bot API Server

First question:

Now, I don’t know how to create a bot to use my local API Server to prevent file size limitation!
I’ve created an application in my.telegram.org and used the given api_hash and api_id in my local API Server.
Does anyone know how should I create a bot without using botfather?! Or should I change some settings in botfather to use my local API Server instead of telegram’s original server?

Second question:

Can I still use the python-telegram-bot package?!
