REST API: get user and post issue
I have some doubts about the redmine rest api.
1. Where can I find more info (more values to be used other than memberships) about the include parameter in the get user rest method?
2. Can I get the user api-key via the get user rest method?
3. Can I specify the user who "created" the issue via the post issues rest method (Let`s say that I give the key of userA when I send the request to the rest service to create an issue, however I want the userB to be the one who created it)?
Thanks in advance.
