### Setup Ad Unit

Please contact your Gravite account manager to agree on the following parameters, as some need to be created on our end.

* Set the "**App ID**" to the itunes app id.
* Set the "**placement ID**" to the Gravite Marketplace placement ID as forwarded to you by your Gravite account manager.
* Set the seller id and the bid floor values in the "**Custom Parameters**" field to `{"sellerId": "<SELLER_ID_VALUE>", "bidFloor": "<BID_FLOOR_VALUE>" }`where `SELLER_ID_VALUE` is the seller id value and  `BID_FLOOR_VALUE` is the bid floor value.

### Implementation Steps

* Integrate `GraviteRTBAppLovinMediationAdapter`
  * Cocoapods:
    * Add AppLovin and GraviteRTBAppLovinMediationAdapter to your Podfile: `pod 'RTBSDK/AppLovinCustomAdapter', '<RTBSDK_VERSION>'`(this will install **AppLovin**, **GraviteRTBAppLovinMediationAdapter** and **RTBSDK**).
  * Swift Package Manager:
    * Follow the same SPM steps [here](https://aatkit.gitbook.io/rtbsdk-ios-integration/start/setup/swift-package-manager).
    * In the last step, select `RTBSPM` and `GraviteRTBAppLovinMediationAdapter`&#x20;

* Integrate with AppLovin fullscreen and banner formats following their [AppLovin documentation](https://developers.applovin.com/en/max/ios/overview/integration/).

{% hint style="info" %}
If your integration is successfully done, you should see logs with this pattern `[GraviteRTBAppLovinMediationAdapter - RTBSDK]:` while testing your integration. If not, please revisit your dashboard and the above steps again.
{% endhint %}

### How **GraviteRTBAppLovinMediationAdapter** Works

* The publisher requests an ad (Banner or Fullscreen) normally from AppLovin SDK (To learn how to request an ad from AppLovin, please visit [AppLovin documentation](https://developers.applovin.com/en/max/ios/overview/integration/)).
* **AppLovin** internally calls **GraviteRTBAppLovinMediationAdapter** asking for an ad.
* **GraviteRTBAppLovinMediationAdapter** internally calls **RTBSDK** asking for an ad.
* When **RTBSDK** responds, **GraviteRTBAppLovinMediationAdapter** would notify **AppLovin** with the response using the AppLovin custom adapter delegate methods. And in return, AppLovin will notify you of the response using the normal AppLovin callback.
