URL Parameters: Question about ID/Name of layers from External WMS/WFS services.
I want to be able to jump into a AGOL MapView with the zoom and scale and a listing of layers to turn on. I can get the URL params to work for the Zoom scale and the Centering, but I have no idea how to ID layers that originate offsite from a WMS service. I've already added the WMS service into the AGOL map (from a WMS catalog link), but where are the Layer names? What's the method for finding the Layer ID in order to turn them on?
Thanks (from a complete Newbie to this )
