Calling external URL from Survey123 form

I have a question about calling external URLS from ArcGIS Survey123 that I other have tried. I have been looking at the help files and community forums but cannot find any examples.

What I want to do is from within a Survey:

Populate a early questions in the first part of the form
Capture these answers and concatenate them into a URL string. This URLS string is an external API from another system
Call this formed URL to the API
Populate additional fields in the Survey123 form based on the return from the URL call

I believe this type of request is possible from ArcGIS Survey123 but I cannot find examples. If anyone has done this sort of reach out to another system I would be interested.

Hi Gordon,

It depends on what the API returns. If it's a simple response (ie. geocoding result from a geocoder/locator for example what3words), then you can use the pulldata@ function to implement it. If the response is more complex (eg. a JSON), you need to parse that (using a JavaScript code) to be able to add the values to the required fields in your form.

I hope this helps.

Thank you zkovacs, I actually found a good article by @IsmaelChivite after posting this question Custom JavaScript functions in Survey123 (esri.com)

This describes what I need to do and also there is sample in the Survey123 connect which helps
