Are some Live Feeds services available to Web App Builder only?

[HasheenDeBerry]

Hello everyone.  I was wondering if anyone knew if some of the Live Feeds services were only available using ESRI's web app builder?  The reason I ask is when I navigate to the following service, http://livefeeds.arcgis.com/arcgis/rest/services/LiveFeeds/NWS_Watches_Warnings_and_Advisories/MapSe..., I am prompted with the following: To acquire this token, go to https://www.arcgis.com and enter 'http://livefeeds.arcgis.com/arcgis/rest' for the 'Webapp URL' parameter.  When I navigate to the link, all I get is a blank page.  I have a custom web application that is simply trying to get the service description in JSON format, but first generates a token using provided credentials.  My ArcGIS Online credentials allow me to connect to other protected services (e.g. Live Traffic) with no problem via my web app.  I can even add this service to a map in ArcGIS Online.  If I use a browser to generate the token, and plug in the generated token, I can get to the service description. When I try to connect using my custom web app, I get an 'invalid token' message back.

A workaround, although not viable, is to share the service via ArcGIS Online.  My web app then connects to the service with no problem. Any feedback you can provide is appreciated.

These layers are Subscriber Content, you'll find their ArcGIS Online descriptions at: http://www.arcgis.com/home/group.html?owner=esri&title=Live%20Feeds

You can consume these from ArcGIS Online web maps, and hosted apps (such as Web App Builder) as long as you are logged in. You should also be able to access these from ArcGIS Pro, ArcMap, etc through their respective interface to ArcGIS Online (again, as long as your are logged in).

If you want to use these in custom applications, check this blog post for more details:

Also, a quick note, the token requested by that REST endpoint your provided a link to, it can be generated through the ArcGIS for Developers site.
