If you are using impersonation for authentication, this allows you to obtain a session ID for a user given their username and password. If successful, the method sets the current user's session token which can be obtained from the getSessionID() method. You should re-use this session token on further calls, rather than logging in for each call. The returned session token is valid for 24 hours after its last use.
Parameters
| $username | The user name to authenticate with |
|---|
| $password | The password associated with the user |
|---|
Return value
There is no return value, but a failed login attempt will throw a LoginException.
