# IEventSender- Global

The IEventSender API provides methods to send events from a MID Server to a ServiceNow instance and to query the status of the event queue.

Before calling any methods within this class, you must call the SNEventSenderProvider.getEventSender\(\) method to instantiate an IEvent object.

Use the Event API to add/update fields within an event. Use the SNEventSenderProvider API to instantiate an event sender object. Then use the IEventSender API to send the event to a ServiceNow instance.

You must activate the Event Management \(com.glideapp.itom.snac\) plugin before attempting to access this API. The Event Management plugin requires a separate subscription and must be activated. This plugin includes demo data and activates related plugins if they are not already active.

For additional information on event management, see [Event Management](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/it-operations-management/c_EM.md).

event.setField("type", "SAP object");
event.setField("user", "admin"); // parameter added to additional info section

var eventSender = SNEventSenderProvider.getEventSender();
var sendStatus = eventSender.sendEvent(event); //send event     
var queueSize = eventSender.getQueueSize() // check the size of the event queue
```

## IEventSender - isFullQueue\(\)
