This call invokes the CLI user exit in the UserCustom Java class.

user_id=username
&password=password OR [&access_token=token-value]
&statevar=custom
[&custom_param1=value[&custom_param1=value...]]
This command works in conjunction with the UserCustom Java class within ExtraView. This command can be used to create your own API calls that execute any code within the ExtraView environment. It is therefore a very powerful command that can be used to create any new API command or commands that you need for any purpose. The custom parameters are optional and may be any name value pairs that you provide to the new command. The parameters are passed into the UserCustom CLI exit.
The optional access_token parameter allows you to use a valid OAuth2 token obtained with the get_token command. If you provide the access_token parameter, then the user_id and password parameters should not be provided. This prevents the password being sent in clear text over your network connection.
