# `GameServer.Payments`
[🔗](https://github.com/appsinacup/game_server/blob/v1.0.26/lib/game_server/payments.ex#L1)

Payment catalog, purchase ledger, and entitlements.

Provider-specific integrations validate or create transactions, but this
context remains the source of truth for what a user owns inside the game.

**Note:** This is an SDK stub. Calling these functions will raise an error.
The actual implementation runs on the GameServer.
