How to: find all or per user, opened MR with prefix WIP

Hello!

Our company use GitLab Enterprise Edition [13.4.2-ee]
And today a task stands front of us: find all opened merge requests with WIP status.
How we can do that?
And can we?

Although I haven’t had the time to really look into the details, using the API seems the way to go: Merge requests API | GitLab . You can get a list of the merge requests, and hopefully filter out the WIP: status MR’s.
Note that the list is a list of MR’s that the user (supplying the api token) can access, so you might need to fiddle a bit to get them all.
