# Test Ad Units

To quickly and easily check if the SDK integration works correctly, we offer the following test ad units that always deliver an ad:

| Format           | Ad Unit ID          |
| ---------------- | ------------------- |
| **App Open**     | `test-app-open`     |
| **Banner**       | `test-banner`       |
| **Interstitial** | `test-interstitial` |
| **Rewarded**     | `test-rewarded`     |
| **Native**       | `test-native`       |

In case of not working, contact us so we can review the integration problems and/or check if there could be a problem with any of these ad units.
