# Meta Bidding

To support Meta Bidding (through GraviteRTB), it is needed to pass Meta indentifier using AATKitAdNetworkOptions when initializing AATKit. See the example below:

{% hint style="info" %}
Please contact your Account Manager to get the `PLATFORM_ID` .
{% endhint %}

{% tab title="Java" %}

```java
AATKitConfiguration config = new AATKitConfiguration(this);
AATKitAdNetworkOptions networkOptions = new AATKitAdNetworkOptions();

networkOptions.setMetaBiddingOptions(new MetaBiddingOptions("<PLATFORM_ID>"));

config.setAdNetworkOptions(networkOptions);
AATKit.init(config);
```

{% endtab %}

{% tab title="Kotlin" %}

```kotlin
val config = AATKitConfiguration(this)
val networkOptions = AATKitAdNetworkOptions()

networkOptions.metaBiddingOptions = MetaBiddingOptions("<PLATFORM_ID>")

config.adNetworkOptions = networkOptions
AATKit.init(config)
```

{% endtab %}
{% endtabs %}
