Attribute rule arcade expression calling webservice and processing result

Jens_Dalsgaard — Mon, 13 May 2024 18:01:55 GMT

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.

Best regards

This would be helpful as many services move to the cloud and replicating data into the GIS is not always possible. Beyond the example on editing I could see this being used for enriching popup data.

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

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.

@XanderBakker

Apologies, I didn't see your response until just now.

Is there any alternatives that I could try? The API call I reference above is the result of an arcade expression but it's easy enough to hardcode the URL as a it's own feature if that means that I can return the result in the feature layer.

HI @NicholeSalinger ,

As I mentioned before within an attribute rule at this moment there is no support for firing REST requests. However, if you are creating your own app using the ArcGIS API for JavaScript you have full control and should be able to code this functionality.

Yes agree this is key functionality in a web services architecture. Yes there are other ways to accomplish the same result but the power and flexibility of this is not to be underestimated. Please make this a priority.

I support this idea (related).

@NicholeSalinger, and for anyone else who’s interested:

As a last resort, in enterprise GDBs, and depending on the DB type (Oracle, etc), we might have the option of making HTTP calls via the database.

For example, Oracle has the UTL_HTTP package that can make HTTP calls from PL/SQL. So in theory, we could use that in conjunction with a database trigger to make a call to an external system.
~~Or make the HTTP call from a database view, and then use that related view in an arcade script: Arcade: Use related DB views as FeatureSets~~

That's far from ideal; it’s complicated, would take some time/effort from the DBA to set up, and would be clunky to manage. But it might work as a very last resort.

I’ve seen it used in systems that aren’t configurable (except through the database) for integrations between systems.

@Bud

Thank you for the advice! I have consulted with my organization's admins about this solution and we found that it would be a big lift considering the number of data sources used in my existing web map application. Hopefully this feature is picked up by ESRI. Thanks again!

To add another use case for the ability to send HTTP requests with Arcade: I'm working on a Field Maps data entry form where an external API needs to be called and passed the user's location, to receive a response that affects an aspect of the form. This is impossible in Field Maps since there is no way to send an HTTP request.

At the 2019 developer conference (maybe the first one after attribute rules were announced/rolled out????) I was in a session that covered using an attribute rule to populate an attribute using a spatial query against another feature class in the same geodatabase (which it should be noted is super useful and way better than the home-baked options we were limited to in the past). At that time the presenter mentioned that only queries within the same geodatabase were currently supported, but accessing other geodatabases (on your LAN) and accessing web services were things that they were working on. I guess it takes more folks upvoting threads like this one to make that happen since that functionality hasn't been released yet.

@AJR Have you ever tried Oracle’s UTL_HTTP package as a workaround?

Is there any updates on this idea? It has been over 3 years since a ESRI person has responded. It was mentioned this was on the roadmap. Being able to call other resources and parse the responses in Arcade seems like something that should be here by now.

more and more customers want to execute php or other url to query databases and retrieve information in json form to format them in an information window.

why doesn't esri implement this capability?

thank you !

I was wondering if the feature for accessing external URLs has already been rolled out in Arcade, or if it's currently on the roadmap for future inclusion. I believe it would be a fantastic addition to the platform.

Looking forward to hearing back from you!
