My goal:
I want to save the session ID of Google Analytics (also need to figure out how to get that) with every order on my (PHP based) website & then use that in order to get additional data from GoogleAnalytics about this specific session (for example: duration, device type, browser, ...).
Note: I know how to collect this data by myself, but for other reasons I need to use the data from GoogleAnalytics.
Note2: I have a basic experience with Google's developers console & I managed to build a basic authentication, save the client's token & get general stuff like sessions count. but I need to get deeper & filter specific information.
-- Is that even possible? & if so - how can I do that?
