Hi @rodrigod3v,

In ServiceNow, JavaScript is the main language used to customize and extend the platform. It’s used for creating rules, scripts, and automation.

ServiceNow uses JavaScript both on the server side apis (for back-end processes) and the client side apis(for user interfaces). and for portal use HTML,css,Angular js and jelly scripts for ui pages.

While JavaScript is the primary language, ServiceNow can connect to other systems using different languages and protocols when needed, like RESTful APIs or web services.

Please mark it as helpful and solution proposed if its serves your purpose.

Thanks,

Anand

ServiceNow provides a scripting environment that supports both client-side and server-side JavaScript. Here's a brief overview of the use of JavaScript in ServiceNow:

1. Client-side Javascript: Client-side scripts are primarily used for enhancing the user interface and experience. You can create custom forms, client scripts, and UI policies using JavaScript to make the user interface more dynamic and interactive.

2. Server-side Javascript: Server-side scripts are used for creating business rules, server scripts, and other server-side customizations. These scripts run on the server, handling various tasks like data manipulation, validation, and server-side business logic.

3. Business Rules: Business rules in ServiceNow are often written in server-side JavaScript. They define the conditions and actions to be taken when specific conditions are met, such as data validation or triggering a workflow.

4. Workflows: ServiceNow's workflow engine allows you to define complex processes using a combination of graphical tools and server-side JavaScript. JavaScript can be used in workflow activities to customize the behavior of a workflow.

5. Scripted REST APIs: You can create custom REST APIs in ServiceNow using server-side scripting, often written in JavaScript. These APIs allow external systems to interact with the ServiceNow platform.

6. Scripted Web Services: ServiceNow supports scripted web services that are created using server-side JavaScript to expose platform functionalities to external systems.

Hi @rodrigod3v ,

• The main scripting language used in Servicenow is JavaScript. JavaScript is used to write server-side scripts, such as business rules, script includes, scheduled jobs, and workflows. JavaScript is also used to write client-side scripts, such as client scripts, UI policies, UI actions, and catalog client scripts .

• Another scripting language used in ServiceNow is Jelly. Jelly is an XML-based scripting language that allows you to create dynamic HTML pages and UI components. Jelly is used to write UI pages, UI macros, UI scripts, and email templates.
