Hello I’ve seen this question asked but never seen a solution... but: is there a way to query the attachment service URL?
I’d like to query the whole attachment table related to a feature service so an application I’m creating can use the URL’s to pull up the attachments.
I can query and capture the data for the service but I can't capture the attachments that are related without iterating through all the object ids.
There is a returnUrl parameter which returns the attachment URL with the results: https://developers.arcgis.com/rest/services-reference/query-attachments-feature-service-layer-.htm#G...
You still have to append a token if it's a secured service though, otherwise the link won't open.
Thanks Michael. But I’ve tried the returnurl parameter. In fact, here is what I tried exactly:
as you can see, I’ve included the returnurl parameter... unfortunately I only get the other data but not the url.
You have to use the queryAttachments endpoint (links in comments above use the query endpoint) which is layer specific (i.e. you must specify FeatureLayer/<layer_number>/queryAttachments). So something like this works (HTML version): https://services5.arcgis.com/v3DMn7xrRivFMRiU/ArcGIS/rest/services/survey123_86170d7dd0954ceb838466f...
