Update/Create User Using API

Update/Create User Using API

Using https://{base path}manageengine.com/api/v3/users/{id of the user} I'm able to find users. I want to be able to make and update users using the API. Whenever I try to use the post or put method I get errors saying Invalid Method. Is there a way I can update/create users using the API?

I can update assets and requests just fine, my scope for users in the OAuth2.0 is
SDPOnDemand.users.ALL
