Systems, methods, and other embodiments associated with complex event pattern building are described. One example method includes receiving, on a server-side, requests associated with user interactions with interactive menus. The method includes responding to the requests with commands that build a set of event-condition-action, data that describes an action to take in response to an occurrence of a complex event pattern. The example method may also include automatically converting the event-condition-action data into a programmatic construct that configures a complex event pattern engine to initiate the specified action in response to detecting an occurrence of the complex event pattern.
