The AppLovin Exchange Test App has two main testing functionalities:
Testing your bidder : Use the DSP Integrations feature to run an end-to-end test of your bidder on the AppLovin Exchange for each ad format that AppLovin supports.
Testing your bid response : Use the Ad Debugging feature under Advanced to test a bid response without pushing it to your bidder.

Use the DSP Integrations section of the app to test your bidder on the AppLovin Exchange end-to-end.
com.applovin.apps.dspdemo for Android and 1590263203 for iOS.Test your bid response without pushing it to your bidder via the Advanced > Ad Debugging section.
When you are ready to launch, AppLovin completes quality-assurance testing and then sets your bidder live with real traffic. Turn off test ads and begin using real campaigns. AppLovin begins by sending 1% of live traffic to your endpoint(s). If AppLovin impression and revenue numbers align, your AppLovin account team continues to increase traffic to your bidder, from 1% to 10% to 100%.
