When integrating with play.fun, we recommend you use the Server-side SDK for the most secure experience. By using the server SDK, your backend has full authority over point submission — users have no ability to interact with Play Fun directly via your client.
Your game has a backend that validates gameplay and controls point awarding
You want server-to-server communication with the Play Fun API
You want to award points conditionally based on server-side logic
You need to batch save points for multiple players at once
You need a hybrid integration — using the client SDK for auth/UI and the server SDK for point saving (see guide)
You have a client-only HTML5 game with no backend
You want the SDK to handle authentication, UI, and point submission automatically
