# Writing an event to power an event-based stat

> Sample XblEventsWriteInGameEvent code that fires an XBOX Live event so configured stat rules update event-based user stats on the service.

This topic provides example code that shows how to write an event.
On the service, this example code updates event-based stats based on the stat rules that you've defined in Partner Center.

#### Flat C API

```cpp theme={null}
HRESULT hr = XblEventsWriteInGameEvent(
    xboxLiveContext,
    "PuzzleSolved",
    R"({"DifficultyLevelId":100, "GameplayModeId":"Adventure"})",
    R"({"LocationX":1,"LocationY":1})"
);
```
