Abstract

With REST (Representational State Transfer) and SOAP (Simple Object Access Protocol) web services, ServiceNow allows IT service management (ITSM) systems to be integrated with other systems. Integration without barriers enables businesses to enhance their operations, collect accurate data, and ensure that systems remain up-to-date and well-integrated at all times. It reviews techniques for making secure and scalable connections to other systems using ServiceNow’s native integration tools, for example, IntegrationHub, Scripted REST APIs and Import Sets. The discussion covers secure authentication methods (for example, OAuth 2.0, Basic Auth, Mutual TLS), different handling of errors, versions and logging. Topics such as avoiding state in interactions, minimizing the time apps take to respond and making use of MID servers and data for data processing are discussed. Because important legacy systems are common, SOAP integration patterns are carefully considered and show that WSDL and XML schemas are still used. The combining of real examples and architectural principles in the article helps developers and architects better integrate ServiceNow with other systems and minimize the risks of data inconsistency, hacks or slow performance. The advice provided here supports the digital transformation of companies by promoting agility, longevity and robustness of integrations.

Keywords: ServiceNow; REST API; SOAP API; IntegrationHub; External System Integration.
