Generating Events

There are two ways to generate events:

• Server-side script using the gs.eventQueue() method
• Workflow Create Event activity

gs.eventQueue() Method

The eventQueue() method is part of the GlideSystem server-side API. The eventQueue() method inserts an event in an event queue. The eventQueue() method is typically passed four parameters but can also take an optional 5th parameter:

1. Event name. Enclose the event name in quotes.
2. GlideRecord object, typically current but can be any GlideRecord object from the event's table.
3. Any value that resolves to a string. This is known as parm1 (Parameter 1). Can be a string, variable that resolves to a string, or method that resolves to a string.
4. Any value that resolves to a string. This is known as parm2 (Parameter 2). Can be a string, variable that resolves to a string, or method that resolves to a string.
5. (Optional) Name of the queue to manage the event.

example:

gs.eventQueue('event.name', GlideRecord, parm1, parm2); // standard form

gs.eventQueue('x_58872_needit.overdueNeedItTask',current,current.number,gs.getUserName());

The gs.eventQueue is a method in ServiceNow that is used to fire an event. This method is typically used in server-side scripting.

Here's a summary of its usage:

- The gs.eventQueue method is used to trigger an event in ServiceNow.
- It is a server-side method, meaning it is used in server-side scripts like Business Rules, Script Includes, etc.
- The syntax for using gs.eventQueue is: gs.eventQueue(String eventName, GlideRecord gr, String parm1, String parm2)
- eventName: The name of the event to be fired.
- gr: The GlideRecord of the record that the event is associated with.
- parm1 and parm2: Optional parameters that can be passed to the event.
- The event that is triggered by gs.eventQueue can be handled by an Event Script or a Notification.
- This method is asynchronous, meaning the script will continue to run without waiting for the event to complete.

Here's a sample code snippet:

javascript
var gr = new GlideRecord('incident');
gr.get('incident_number', 'INC0010001');
gs.eventQueue('custom.event', gr, 'parameter1', 'parameter2');

In this example, a custom event named 'custom.event' is fired for the incident with number 'INC0010001', and two parameters 'parameter1' and 'parameter2' are passed to the event.
