# Sending Test Callbacks

To check your server-side rewarding setup, send a test callback to your configured callback endpoint for Offer Wall rewards. DT sends the test callback in the same method and format as an actual reward notification. For more information about setting up the callback endpoint for Offer Wall rewards, see [Server‑Side Rewarding](https://app.gitbook.com/s/7drDlNSyycpmA7Zx8kgX/publishers/task-specific-guides/rewarding-your-users/server-side-rewarding).

{% hint style="info" %}
The test callback includes custom parameters (`pub0` … `pub9`) as indicated in your SDK integration.
{% endhint %}

Test callbacks from the **Reward Handling** section of the **Settings** tab of the **Application Details** screen:
