i want to create a digital course landing page on shopify, how to create an automation for it?

[AceDesigns]

hey, i want to create a digital course and sell it online, i tought about making the landing and front page in shopify, and then connect shopify into another digital course that made just for that ( since i didn’t find any digital course solution in the app store, that lets you watch the courses on the site it self.)

anyone have any idea how can i make this come to life? 
maybe create an automation that when someone buys a course he gets tagged with a specific tag and then the tag list connects to the 3d party digital course with Make? but how can i do that efficiently?
