According to the documentation on updating order hints in planner.
The client can obtain the values immediate if return=representation preference is specified in the PATCH requests.
I've tried putting this in the header, and as a query parameter, but I still only get back a 204 response.
Where in the PATCH
request, does the return=representation
go ?
The graph sdk team enlightened me. The header Prefer:return=representation is what needs to be set.
