Our library is required for certain types of services, such as interstitial and rewarded ads. This is because those types of services need more information from your app, such as when and where to be called.
You can download the Drag and Drop Library from the bottom of this page: https://enhance.co/documentation. Simply choose the dev platform in which you created your app from the dropdown, and the download will start automatically.
Within the download, you'll find a readme explaining how to use the library to access the various services we support, as well as a demo application for you to import into your development platform to test.
