About Advanced ServiceNow Scripting
ServiceNow is a powerful cloud-based platform that streamlines IT service management (ITSM), IT operations management (ITOM), and IT business management (ITBM). Advanced scripting in ServiceNow enables developers and administrators to customize workflows, automate processes, and enhance platform functionality beyond standard configurations.
ServiceNow scripting primarily involves JavaScript, leveraging both client-side and server-side scripting to build custom applications and integrations. Advanced scripting techniques allow users to optimize business processes, enhance user experiences, and integrate third-party applications seamlessly.
Key Areas of Advanced ServiceNow Scripting
1. Client-Side Scripting
Client-side scripts run on the user’s browser and enhance the user interface (UI) experience. Some of the most commonly used client-side scripting options in ServiceNow include:
a) Client Scripts
Client scripts execute on form fields and UI components. They are used for:
Field validation
Auto-populating form fields
Modifying UI behavior dynamically
Example: Setting a field value dynamically
javascript
CopyEdit
function onLoad() {
g_form.setValue('priority', '1'); // Sets priority to High
}
b) UI Policies
UI policies are a no-code alternative to client scripts. They enable dynamic form behavior without requiring JavaScript. However, for more complex scenarios, client scripts offer greater flexibility.
c) UI Actions
UI actions allow users to create buttons, links, and context menus that execute custom scripts.
Example: Creating a button to approve a request
javascript
CopyEdit
function approveRequest() {
var gr = new GlideRecord('change_request');
gr.get(g_form.getUniqueValue());
gr.approval = 'approved';
gr.update();
}
Server-Side Scripting
Server-side scripts run on the ServiceNow server and interact with the database. Common types of server-side scripting include:
a) Business Rules
Business rules execute before or after database transactions to enforce business logic.
Example: Automatically assigning a group when a new incident is created
javascript
CopyEdit
(function executeRule(current, previous) {
if (current.category == 'network') {
current.assignment_group.setValue('Network Support Team');
}
})(current, previous);
b) Script Includes
Script includes store reusable functions that can be called from multiple scripts, improving maintainability.
Example: Creating a reusable function for logging messages
javascript
CopyEdit
var CustomLogger = Class.create();
CustomLogger.prototype = {
initialize: function() {},
logMessage: function(message) {
gs.info("Custom Log: " + message);
},
type: 'CustomLogger'
};
c) Scheduled Jobs
Scheduled jobs run automated tasks at specified intervals, such as data cleanup or report generation.
Example: Deleting inactive users every 30 days
javascript
CopyEdit
var cleanupUsers = new GlideRecord('sys_user');
cleanupUsers.addQuery('active', false);
cleanupUsers.addQuery('last_login_time', '<=', gs.daysAgoStart(30));
cleanupUsers.deleteMultiple();
Integration and Automation with ServiceNow Scripting
Advanced scripting also involves integrating ServiceNow with external systems and automating workflows.
a) REST API Integration
ServiceNow provides a REST API framework to interact with external applications.
Example: Fetching data from an external API
javascript
CopyEdit
var request = new sn_ws.RESTMessageV2();
request.setEndpoint('<https://api.example.com/data>');
request.setHttpMethod('GET');
var response = request.execute();
gs.info(response.getBody());
b) Workflow Automation
ServiceNow scripting can be used to automate workflows in Flow Designer and Orchestration modules.
Example: Automating approvals in Flow Designer
- Create a flow
- Add a trigger (e.g., when an incident is created)
- Use a script action to set approval status
c) Scripted REST APIs
ServiceNow allows creating custom REST APIs using Scripted REST APIs.
Example: Creating a custom endpoint to retrieve incident details
javascript
CopyEdit
var IncidentAPI = Class.create();
IncidentAPI.prototype = {
getIncidentDetails: function(incidentId) {
var gr = new GlideRecord('incident');
if (gr.get(incidentId)) {
return gr.short_description;
}
return "Incident not found";
},
type: 'IncidentAPI'
};
Best Practices for Advanced ServiceNow Scripting
- Follow ServiceNow Guidelines – Use built-in features whenever possible before resorting to custom scripts.
- Optimize Performance – Avoid unnecessary loops and database queries. Use GlideAggregate for optimized queries.
