Is there any way to use the ArcGIS API for Python to add a layer (i.e. add_layer()) to a web map object if it is NOT registered as an item in ArcGIS Online?
I'd like to add a service from AGS to a web map, but I don't have it as an item.
For that matter, is there any way to simply update the URL of a layer in a web map (e.g. ArcGIS Online Assistant)?
I have a service that needs to be updated in web maps, but only a few letters of the URL path need to be changed.
Any way this can be accomplished?
