Integrate PlayFab CloudScript (Azure Functions) to run server-authoritative game logic

Steps

1. In PlayFab Game Manager, navigate to Automation > CloudScript > Functions and register an Azure Function endpoint by providing its HTTPS trigger URL and a function name.
2. Deploy your Azure Function with an HTTP trigger; the function receives a POST body containing FunctionArgument (your custom payload), CallerEntityProfile, and TitleAuthenticationContext — use these to validate the calling player.
3. Call the function from your game client via POST /CloudScript/ExecuteFunction with the FunctionName, FunctionParameter payload, and the player's Entity Token in the X-EntityToken header.
4. Use the PlayFab Server SDK or direct REST calls with your title's secret key inside the Azure Function to perform authoritative actions (e.g., grant items, update stats) that clients must not perform directly.
5. Return a result object from the Azure Function; PlayFab wraps it in the FunctionResult field of the ExecuteFunction response delivered to the client.
6. Enable logging in your Azure Function and monitor execution results in Game Manager under Automation > CloudScript > Revisions for debugging.
