Extract feature layer attachments in a zip file

[JamesOllerton]

Looking for advice on how to create a web mapping application in arcgis online.  I have a feature class with attachments. I want the user to be able to select features and click a button to export only the attachments from the feature into a zip file.  What would be the best api to use for this use case?  Thanks Jim

I have a similar interest, Jim. I didn't see anything in the API documentation that will do this (correct me if I'm wrong). This post from 2017 indicates that the JS API is somewhat limited when it comes to working with attachments. The REST API for ArcGIS Server might be a help.
