Documents & JSON

Question

Hi, 
 Does anyone know how to convert a document stored in appian to an url? to use it as a dynamic link in a json. 
 Thanks!

Downloads are only available to a logged-in user viewing an active interface. There's no supported way to grab an externally-usable URL for a document download, as Appian requires that downloads are only accessible by users in the proper security roles/groups.

This method is not sanctioned by Appian but it will work if you share it with someone who is authenticated. 
 a!localVariables(
 local!documentDownloadLink: a!documentDownloadLink(
 document: cons!NZC_CSO_IMAGE_DOCUMENT_ID
 ),
 local!urlPrefix: "https://<APPIAN_URL>/suite/rest/a/content/latest/",
 concat(
 local!urlPrefix,
 local!documentDownloadLink.@attributes.@anyAttribute._documentDownloadLink,
 "/o"
 )
)

Be aware that this is part of the internal implementation and can stop working any time. 
 BTW, providing a file for download is pretty simple. Just create a web API in Appian. This uses official functionality, is stable and easy to use.

Can you tell us a bit more about your use case? I'm unclear what approach you're even going for here. If, for instance, you want to allow a user to download the file from an Appian interface, you'd use the Document ID in a Document Download Link (preferably in a Rich Text Display), wherein they'd be able to click that link and download it. Appian handles the URL creation involved, ther isn't really a way to manually construct such a URL directly.
