Hello @sasharma815,

 

That's expected, and technically not a redirect: the download_link from the Attachment API is a plain instance URL, not a signed or token link. So the file endpoint needs the same authentication as any other instance request. Open it in a browser tab with no active session and you get a basic auth challenge instead, that's the native "Sign in" box you're seeing.

  1. Same browser, already logged into the instance: the link opens fine, no prompt.
  2. Script or integration calling it: pass an OAuth token or basic auth credentials in the Authorization header.
  3. Surfacing it through Virtual Agent to end users: use the Attachment output component in VA Designer instead of the raw download_link, it handles the authenticated fetch for you.

 

Thank you,
