Editing Experience data sources via JSON and ArcGIS for Python

Question

Hello,
I will use ArcGIS for Python to create feature layers from a registered database and turn those layers into published web maps. I have created templates in Experience Builder and would like to simply change the data sources used in an existing experience without having to recreate it using the GUI. The schema are exactly the same. The only difference is the source.

My use case is an analysis of hospital systems by clinic type (primary, pediatric, etc.). Each clinic type will have an experience. Each hospital system will have three experiences embedded. And then, the state will have an experience where each system is accessible. But to do this I cannot possibly recreate and rewrite all of the queries I have set up for layer, for lack of a better word. The only thing that actually needs to change is the data source.

My attempts to write the JSON with the updated data sources results in a data source cannot be accessed error.

Help is greatly appreciated.

Would this same approach work for applying popup configurations from one web map to another, as long as the fields in the new web map are identical to those in the initial map where popups were configured through the UI? Any suggestions/examples of accessing the pertinent part of the JSON (i.e. the popup configuration section) in a way that can be generalized automated? Thanks everyone who has weighed in, I just started looking into the ArcGIS Assistant and editing JSON as a way to (semi)automate reproduction of thematically consistent web maps/web apps and this seems very promising, but I'm still new to the idea. Any suggestions/resources appreciated!

Thanks for the info!

I've been editing the config.json directly in the editor, but when I do that, my dynamic-data substitutions and some styling configurations get reset/removed.

By saving the config.json and then uploading it seems to fix that problem. Game changer for me!

As stated by MGEGIS, use ArcGIS Assistant: https://assistant.esri-ps.com/

(This is different than ArcGIS Online Assistant).

Only thing I would add and say here more explicitly is that you have to edit the json and then save it to a config.json file. From the link above, you can choose to then import and replace the file at the config/config.json directory for experience builder.
