About the Ad Placement API
The Ad Placement API supports interstitial (including prerolls) and rewarded ads. Developers can use the API to create potential ad breaks in their games or other interactive media. The API takes care of deciding exactly when to show ads, taking into account many factors including the type of placement, whether a suitable ad exists, the frequency that ads are being shown, and more. You can control these settings without having to release a new version of your game.
The Ad Placement API is designed to make placing interstitial and rewarded ads simple. This guide walks you through the key concepts of the API, provides best practices, shares a full example app, and shows you how to use this API when your games are loaded in a mobile app.
