Redmine

As Rest_IssueCategories notes,

PUT
Updates the issue category of given id

Parameters:

Same as issue category creation

Response:

200 OK: issue category was updated
422 Unprocessable Entity: issue category was not updated due to validation failures (response body contains the error messages)

I had test this function as:

/redmine/issue_categories/{1}.json?id=117&key={0}

then body given json data

{"issue_category":{"name":"Test", "assigned_to_id":1}}

and it's update the category name and assigned_to correctly
but response Status is 204 No Content.
Thanks.
