# Server-Side Verification (SSV)

Publishers can provide an identifier to AATKit, which will then forward it to ad networks that support Server-Side Verification (SSV).

For greater privacy, it is recommended to encrypt or hash the UserID and related data before transmission.

**Usage:**

To implement this, pass an [RewardedAdSSVInfo](https://android-sdk.aatkit.com/references/-a-a-t-kit/com.intentsoftware.addapptr/-rewarded-ad-s-s-v-info/index.html) instance to AATKit, which will then forward it to supported ad networks:

{% tabs %}
{% tab title="Java" %}
```java
AATKit.setRewardedAdSSVInfo(info);
```
{% endtab %}

{% tab title="Kotlin" %}
```kotlin
AATKit.setRewardedAdSSVInfo(info)
```
{% endtab %}
{% endtabs %}
