# Launch Offerwall

## Open the Offerwall

Call this function after initialization to show users the Playtime Offerwall.

```csharp
// Open OfferWall
PlaytimeAdsManager.Instance.OpenOfferWall();
```

This allows users to interact with offers and earn rewards within your app.

***

## Clear Session on Logout

Don't miss to clear Playtime session when users logout from the app.

```csharp
// Optionally destroy SDK
PlaytimeAdsManager.Instance.DestroyPlaytimeAds();
```

***

### ✅ Best Practices

* Make sure you initialize SDK using `InitializeWithUserId` before opening the Offerwall.
* Use consistent User IDs to ensure proper user tracking.
* Call `DestroyPlaytimeAds` when SDK usage is complete.
