Idempotency keys

Retry mutation requests only when the public contract says it is safe.

Not yet available for public mutations — the current contract does not define an Idempotency-Key request header.

Do not assume that repeating a POST is safe. If a response is lost, inspect the operation outcome before retrying. This page will document key lifetime and replay behavior when the header becomes part of the public contract.

Open the published OpenAPI JSON to verify the headers accepted by an operation, or read the developer API map.
