ATS API
Use the API to set up a customized ATS implementation.
This is required if you need to integrate ATS into properties outside the web or you need to limit added Javascript on your pages.
ATS for Web (ATS.js)
Use the LiveRamp Publisher Console to configure ATS.js for use with Prebid.js.
This is recommended if you want a quick, automated process that allows you to use one interface to manage all your publisher products.
