Upon insert or move of a feature I would like to call a service (using X and Y of the feature as input) and use the returned result for updating an attribute on the feature in question. This seems like something I should write an Arcade expression for. Apparently this is not supported for now.

I believe such capability is highly relevant considering Esri promoting the service-based architecture. Anyone out there agreeing, please give it a vote.

Esri - should you already be considering this please let me know of the roadmap.

I have a similar request that Arcade allow API calls from and then parse the JSON results so I can visualize the info in the pop-up.    Here's an example of the results from




Hi @NicholeSalinger ,

As far as I understand being able to make a REST request and parse the returned JSON is something that is on the roadmap. Unfortunately, I don't have an ETA on when this will be available. Once available, this will open a huge amount of possibilities.
