thinking that it may also able us to copy-paste Custom WF directly in the API section (not as endpoints but WF of course). I get that action with API are very different from action with common WF, but telling you is a bit frustrating having to re-write again one-by-one the API WFs.
I trigger endpoints from different pages of my app. So I would prefer having some logic at the API level than copying the same logic on these pages. But right, I can use a Custom WF in a reusable element to do so.
