This feature provides support for serving the "ads.txt" and "app-ads.txt" files from within the web app. Most customers prefer to host their own website on the "www" hostname of their domain, with the web app being configured as a secondary hostname (such as "browse.mydomain.com"). However, if you are using the web app as your primary website, then requests for these files will be sent to the web app rather then your own website.
How to Use
To allow the web app to serve these files on your behalf, find the "Authorized Digital Sellers" settings section of the "Web" platform (on the Platforms page):
Any values entered into these fields will be served for requests made for requests to "/ads.txt" and "/app-ads.txt" URLs on the web app, respectively.
