ServiceNow Scripting Full Course: Script Include and Glideajax in Servicenow | Secure Coding
In this video, we walk through a clean and scalable way to handle data validation in ServiceNow using a refactored EmployeeEntity class. Rather than duplicating logic across layers, we apply object-oriented design principles and assign validation responsibility directly to the entity.
You’ll learn how to:
✅ Use ValidationHelper for reusable, centralized checks
✅ Eliminate redundant validators like EmployeeRequestValidator
✅ Keep your business logic clean with a simplified EmployeeServiceWrapper
✅ Catch invalid or malicious data early using try/catch
✅ Build secure, enterprise-grade code that protects data integrity
✅ Guard against simulated attacks and improper API input
This approach is built for ServiceNow developers and architects who care about writing scalable, secure, and future-ready backend logic using Script Includes.
🎯 If you want to build clean ServiceNow architectures that resist bad data and ensure trust in your logic, this one’s for you.
