Question

When viewing a case via the XML API, when does the API call mark the case as viewed, and how can I control if this happens?

Case FC1906928

Answer 1

The view command will mark a case viewed up to a given ixBugEvent, if supplied, or for the latest bug event otherwise.

See Mark as viewed in the XML API docs.

Note: to mark a case as completely unread, use ixBugEvent=1 (not 0 as you might expect)
