D&B Direct+ Monitoring API
The Monitoring surface lets customers register a portfolio of D-U-N-S Numbers and subscribe to change events. When D&B detects an update to a monitored attribute — address, ownership, financials, risk rating, executives, business status — the change is delivered as a notification package (typically via SFTP pull file or webhook-style delivery) that downstream systems can replay to keep master data current. Monitoring is the streaming complement to Enrich's pull model.
