Overview
ServiceNow provides comprehensive integration capabilities through REST APIs, SOAP web services, Import Sets, and Integration Hub. Developers can create Scripted REST APIs for inbound integrations, use RESTMessageV2 for outbound calls, and leverage Import Sets with Transform Maps for bulk data loading.
Why It Matters for the Exam
Integration & REST APIs represent 15% of the CAD exam. Questions cover building REST integrations, creating Scripted REST APIs, configuring Import Sets and Transform Maps, and understanding authentication methods for web services.
Key Concepts to Master
💡 Exam Tips & Strategy
Know the difference between Table API (standard) and Scripted REST API (custom). Understand REST authentication methods (Basic, OAuth, mutual TLS). Remember that Import Sets create staging tables and Transform Maps define the mapping to target tables. Be familiar with coalesce fields for update-or-insert logic.
