# Send Actions to License Server

You operate License Server by sending actions from your Web browser. The general syntax of these actions is:

    http://Host:Port/action=action&requiredParams&optionalParams

where,

`Host` | is the IP address or name of the machine on which License Server is installed.
`Port` | is the ACI port by which actions are sent to License Server (set by the `Port` parameter in the `[Server]` section of the License Server configuration file).
`action` | is the name of the action that you want License Server to run.
`requiredParams` | are the parameters that you must supply for the action. (Not all actions have required parameters.)
`optionalParams` | are parameters that you can supply for the action. (Not all actions have optional parameters.)

NOTE: Separate individual parameters with an ampersand (&).
