Usage notes

  • Responses reflect the current authoritative resource state.
  • Send a unique Idempotency-Key. An exact retry returns the stored result; reusing the key with a different request fails.
  • The request is accepted only when its credential, authority, case state, and resource preconditions are satisfied.
