x-idempotency-key identifies one intended action. Generate a unique value, such as crypto.randomUUID(), before sending it. Use 1–128 letters, numbers, hyphens, underscores or periods. A duplicate attempt is rejected; it does not return a cached success. If a request times out, check the provider’s state before starting a new attempt with a new key. See the idempotency guide.
