Deduplication Window
The length of time for which a server retains records of idempotency keys. A retry with the same key within the window is identified as a duplicate, while a request arriving after the window has elapsed is treated as a new request.

The platform convention defines an idempotency key request header and provides a default 24-hour deduplication window; retries with the same key within 24 hours are recognized as duplicates, while beyond that they are treated as new requests; the client should generate the key before initiating the request and persist it, reusing the same key when retrying.
