How to sell premium and does it earn your game money?

I have heard that you can sell premium in your Roblox game. If so I am wondering how you would do it. Also how would you give players that have premium special items, I am wondering how you would check if the player has premium

I have looked it up but I didn’t find anything useful. I might be searching up the wrong thing but I have come blank.

After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!

Sorry if this is in the wrong place I didn’t know where to put it.

To prompt premium: MarketplaceService | Documentation - Roblox Creator Hub

To detect when the prompt UI is closed: MarketplaceService | Documentation - Roblox Creator Hub

Thankyou this is great! Also will I make a profit off of this?

Premium sales don’t get you anything unfortunately. But you will want to implement incentives in your game. Benefits that only premium users get so they are encouraged to stick around longer and to attract new players who have premium.
