PutResourcePolicyRequest

The write succeeds only if the named policy's current revision ID matches this value; a policy that does not exist yet matches only the sentinel "NO_POLICY" (create-only). On mismatch the operation fails with ConflictException. When omitted, the write is unconditional. Every attempt stores a newly generated revision ID, so retrying an unanswered request can conflict with the caller's own earlier attempt; read the policy back and compare it with the one you intended before treating a conflict as another writer's change.

A resource policy document, as a JSON string. The "default" policy can be up to 20 KB (20,480 bytes of UTF-8) by default. This quota is adjustable in Service Quotas. A "default" policy that exceeds the quota is rejected with PolicyLengthExceededException. No policy document can exceed 389,120 bytes of UTF-8, regardless of the quota.

Which named policy to write. Defaults to "default", the customer-managed policy, when omitted (a write AWS Resource Access Manager makes on the owner's behalf resolves to "AWS_RAM" instead). The two writers are exclusive in both directions — only Resource Access Manager can write "AWS_RAM", and only the bus owner can write "default" — so naming the other party's policy fails with AccessDeniedException. A well-formed name that is neither of the two fails with InvalidInputException.
