To be more concrete we have 2 separate applications that you can use together. First app can display a link to document in second app if document is there. What we do is checking via API if document exists - show the link to open it. Only if user would try to open the link 404 would be correct. Checking if app should show the link 200 with true/false makes much more sense.
