To authenticate, use the Superuser ID and the authentication (auth) target.
Use the authentication command target (auth) to authenticate using the POST method. In this process, you provide a username and password through the X-Auth-Username and X-AuthÂPassword header fields. The beginning of the session is the only instance where you must enter the username and password. Upon successfully entering the username and password, an authentication token is displayed. This token is a 32-digit, hexadecimal code that you include in future commands using the X-Auth-Token header. The X-Auth-Token header in combination with the authentication token replaces the username and password for each action. The token is good for one session, but after two hours of activity or thirty minutes of inactivity, the session times out. Repeat authentication for another token.
