What role do "REST API calls" have in ServiceNow Discovery?

The role of REST API calls in ServiceNow Discovery is significant because they enable integration with external systems and applications, which enhances the Discovery data. By using REST APIs, ServiceNow can communicate with third-party platforms, allowing it to pull in additional data that might not be available from internal resources. This integration facilitates a more comprehensive view of the IT landscape by aggregating data from various sources, thereby enriching the information collected during the Discovery process.

Through these API calls, organizations can connect to cloud services, external databases, and other IT management tools to gather information about assets, configuration items (CIs), and their relationships. This capability is vital for effective IT asset management and ensures that the ServiceNow environment remains up-to-date with the latest configuration details from all relevant systems.
