# Rewarded Video Ads
> Implement rewarded video ads in your React Native app.
## Rewarded Video Ad Format
Provides in-app rewards (currency, features, content) in exchange for watching video ads. Videos are non-skippable and typically run 30 seconds.
### How It Works
***
## Implementation
Rewarded ads use the Hook API. `useRewardedAd` manages loading state and reward callbacks together inside your component.
The previous static API (`RewardedAd.loadAd` and friends) is deprecated. Static listeners such as `RewardedAd.addAdLoadedEventListener` do not receive events for ads loaded through the Hook or instance API — when you move ad loading to the new API, move the event listeners with it.
```javascript theme={null}
import { Button } from "react-native";
import { useRewardedAd } from "react-native-daro";
function RewardedAdButton({ adUnitId }) {
const { isLoaded, isLoading, load, show, isAdReady } = useRewardedAd(
adUnitId,
{
onLoaded: (adInfo) => {
// Ad loaded
},
onLoadFailed: (errorInfo) => {
// Ad failed to load
},
onReceivedReward: (rewardInfo) => {
// Reward granted
},
onHidden: (adInfo) => {
// Ad dismissed
},
onImpressionRecorded: (adInfo) => {
// Impression recorded
},
}
);
const handlePress = async () => {
if (await isAdReady()) {
show("CUSTOM_DATA");
return;
}
load();
};
return (
);
}
```
## Rewarded Video Callback Methods
* The code below shows how to tag your internal User ID and pass CustomData to the callback.
* The User ID string can be up to 8192 characters.
```javascript theme={null}
setUserId("${USER_ID}");
// Pass CustomData to the show function returned by useRewardedAd.
const { isLoaded, show } = useRewardedAd(REWARDED_AD_UNIT_ID);
if (isLoaded) {
show("CUSTOM_DATA");
}
```
