What it does: Deletes every saved mapping of your account, across all hotels. Requires ?confirm=<your account id>; the dispatcher checks it before forwarding and the mapping service checks it again. A hotel with a job of yours in flight is skipped, not purged, and listed in busyHotels. One run per minute (429).

Destructive and immediate; every purge is written to your mapping audit log.

Available to accounts with their own isolated room-mapping cache; others receive 409. Details: Implementation Workflow (doc page: implementation-workflow).
