Roblox monetization

Product types

Type	Buy	Use for	Grant via
Developer product	Repeatedly	Currency, consumables, boosts, revives	`MarketplaceService.ProcessReceipt` (server)
Pass	Once, permanent	VIP, permanent perks, extra slots	`UserOwnsGamePassAsync` check on join + purchase-finished event
Subscription	Monthly, revocable	Recurring perks (daily currency, VIP)	`GetUserSubscriptionStatusAsync` + `UserSubscriptionStatusChanged`
Rewarded video ad	Free (watch ad)	Small rewards (≈3–10 Robux value)	Developer product granted through `ProcessReceipt`
Commerce product	Real money (physical goods)	Merch with bundled digital benefits	`CommerceService`; digital benefits via `ProcessReceipt`
Private server	Monthly	Paid private servers	Configured in Creator Dashboard

All granting happens on the server. Never grant from client events like PromptProductPurchaseFinished — clients can fake them.
