Sage 300 Premium (Version 2022) Software Integration Documentation

SOLVED

This is my first time working with Sage software.

I have a Python web application running on the same Microsoft Server as Sage 300 Premium (Version 2022). When a payment is completed through the web application I need to associate the payment, payment source, etc with Sage 300 so the transaction is linked to the relevant item in Sage. 

Are there application api (web api not installed on the server currently) documents I can get a hold of to be able to integrate my software? Where would I find them? Can the APIs be called from Python?

Thanks!
