What You Will Learn
Scripted REST APIs:
Build, test, and manage your own APIs in ServiceNow.
Create endpoints for common tasks such as creating, reading, updating, and deleting records.
Apply versioning to support ongoing changes without affecting current users.
Real Projects That Matter:
CityWeatherInfo Application:
Design a complete application to manage weather data for different cities.
Set up roles, groups, tables, and fields that form the backbone of the app.
Create multiple API endpoints to interact with external data from services like OpenWeather.
Implement a business rule that automatically updates weather data when records are added or changed.
Use a scheduled job to refresh data regularly and create simple dashboards to visualize information.
Two-Way Instance Integration:
Keep user records synchronized between two ServiceNow instances.
Use business rules to trigger REST calls when a user record is created or updated.
Compare update timestamps to ensure that only the most recent data is maintained across both systems.
Set up GET, PATCH, and POST requests with proper error handling to keep data consistent and secure.
Security Best Practices:
Learn how to configure Access Control Lists (ACLs) and OAuth settings to secure your APIs.
Understand how to apply IP restrictions and basic authentication to protect data transfers.
Use clear logging and error management techniques to troubleshoot integration issues effectively.
Testing and Troubleshooting:
Gain hands-on experience with ServiceNow’s REST API Explorer and external tools like Postman.
Follow step-by-step instructions to test each endpoint and validate that your integration works as intended.
Hands-On, Practical Learning:
