To perform an idempotent request, provide the idempotency_key query parameter with the request. An idempotency key is a unique value generated by the client which the platform uses to recognize subsequent retries of the same request. How you create unique keys is up to you, but we suggest using a V4 UUID, or another random string with enough entropy to avoid collisions. Idempotency keys can be up to 255 characters long.

The version of the policy being issued. Can be a UUID or one of live, draft.
