DELETE is the correct idempotent method for resource removal.
Why this answer
The DELETE method is the standard RESTful way to remove a resource, and it is defined as idempotent, meaning multiple identical requests result in the same state (the resource is gone).
When using the Cisco Umbrella Reporting API, which format is the default output for retrieving threat activity logs to ensure compatibility with most data analysis tools?
