# Game to Web Events Firing

To send events from the game to ArcPlay, a message will need to be posted to the parent of the iframe in which the game is running. An example of this would be:

```javascript
// Sent when user started the game
parent.postMessage({funcName: "game_start_success"}, "*");
// Sent when the web needs to show a rewarded video ad
parent.postMessage({funcName: "game_reward_click", rewardParams: { itemId: 1 }}, "*");
```

The data will be in the format `{ funcName: “string”, …other data }` where `funcName` is the name of the event and any other data is sent as additional parameters. It can be one of the following.
