The correct answer is Service Graph Connector . Service Graph Connectors are ServiceNow-supported ingestion solutions designed to bring third-party data into the CMDB using governed, repeatable, and upgrade- safer patterns. They are built to align with CMDB class models, Identification and Reconciliation Engine processing, source tracking, and ServiceNow data quality practices. This reduces custom scripting, unsupported mappings, and long-term maintenance burden. A generic vendor-provided integration may work, but it can introduce technical debt if it bypasses IRE, writes directly to CMDB tables, or uses unsupported mappings. Import Sets and Transform Maps can be used, but they require careful scripting and governance to avoid duplicates. Table API is the riskiest option because direct table writes can bypass CMDB identification and reconciliation logic. Therefore, Service Graph Connector is the best method to minimize technical debt.
