IT service desks are essential systems for IT teams, facilitating the tracking of requests, incident responses, and management of system changes through APIs like those of Jira, ServiceNow, and Freshservice. These APIs enable integration with internal systems and SaaS products, supporting key concepts such as data schemas for tickets, which represent incidents, problems, and changes, and are linked to contacts within organizations. Common use cases for IT service desk APIs include integration with source code management, CI/CD systems, asset management, compliance management, and monitoring tools, enabling seamless tracking and approval of changes, vulnerability detection, and compliance tasks. Merge offers a Unified API that simplifies integration by consolidating multiple IT service desk APIs into a single REST-based API, streamlining authentication, pagination, and rate limiting, while also providing automated logging and issue detection.
