Can anyone provide an example or point me in the right direction on how to copy and edit a web map in ArcGIS.com using the REST API? I've read the documentation on web maps in the ArcGIS REST API Maybe I missed it but I don't see any examples of how to create/save or edit an existing web map. It just documents the web map format. Which is fine, I could use the documentation to write a web map with the correct specifications but I don't know how to save it to my ArcGIS.com site and give it a web map ID.
I've used the ArcGIS Online Assistant which is very useful but again it doesn't really help me automate it.
What I would like to do is write a script that creates or copies a web map and changes the filter on a layer in the map. Has anyone done this before or have any suggestions?
