Roblox data requesting knowledge needed!

Hey developers! I am working on a game that needs to receive limited assets from the Roblox marketplace. I would assume I would do this with RoProxy. The only thing is though, is that I don’t know how to use RoProxy in any way. I don’t just want to know how to get limited assets, I want to know everything there is to getting information from Roblox. If you know anything about even the slightest bit of this, please comment! Thanks!
