Thanks for these tips.

These would be more useful as code blocks for copy/paste ease. Someone already mentioned that above, but it also would help with SEO, because I will probably never find this post later when I need it. Adding a bit of text with keywords about what these do will help. I know what updateWMLayerItemID means when I read it, for example, but I'll never manage to search on that months from now when I actually need to do it.

That's great, thanks for the write-up. But it would be really nicer and helpful if your snippets were posted as code blocks instead of images, don't you think?

thanks for sharing.

I've been using the above approach updating the layer source, i.e to point a layer Url into another one

The methodology to update a web map can be summarized as such:

Get the web map json (item.get_data())

Similar to the ArcGIS Rest API:
https://developers.arcgis.com/rest/users-groups-and-items/item-data.htm

2
Prepare the web map dictionary by overwriting the chosen dictionary values with the desired values:

3
Update the target web map (item.update(item_properties=desired web map dictionary keys:values))
