but it doesn't make any notes on the compatibility between different versions.
The particular API you linked to is not in any way related to ANY version of QuickBooks. It's the AggCat APIs, which are geared towards pulling financial information from banks (e.g. Wells Fargo, Bank of America, etc.).
If you're trying to integrate with QuickBooks accounting software:
If you're a SaaS application (e.g. you are building an app to allow many people to connect their QuickBooks to your app) then this is where you need to look:
