Create a user in the account specified in your own API client credentials or clone an existing user's role assignments. Optionally, send a randomly generated one-time use password to the new user. If you send the email with the password directly to the user, the response for this operation doesn't include that password. If you don't send the password to the user through email, the password is included in the response.
