Connect Binance API

Hello, i am building an app and one of its features is to automate trade across platforms. I want to use the binance API but i find the documentation quite difficult to understand. How can i get around this? Thank you in advance.
Here’s the API documentation : https://www.binance.com/en/binance-api

Probably this section may be more helpful:

I can’t really locate what i want.
I want to allow users to log in with their binance account on my platform and then place trades with an automate bot. Can you please be more specific?
