  description: >
    Organization management: organizations, accounts, human users, users-only
    groups, and organization policies. Account IAM identities may receive
    explicitly delegated organization policies through this API. Personal
    authentication remains at the IAM endpoint.


    Organization resources are global and are resolved in the authenticated
    organization. Canonical CRNs are
    crn:workspace:::organization/<organization-uuid>/<type>/<name-or-uuid>.
    Organization policies are separate from account policies; shared system
    policies use crn:workspace:::policy/<name>.

        Optional client-generated key that makes a create replay-safe. Retrying
        a request with the same key returns the original outcome verbatim
        instead of creating a duplicate resource. Reusing a key with a different
        request body is rejected (422); a request whose key is still being
        processed returns 409. Records are honored for 24 hours. Use a UUID or
        similarly unique token.

        The request is well-formed but cannot be processed as sent. On the
        operations that accept `Idempotency-Key` this is the key-reuse case: the
        key was first seen with a different request payload, so replaying the
        stored outcome would answer a question the caller did not ask.

      description: |
        An OAuth 2.0 bearer token, sent as `Authorization: Bearer <token>`.
        This is the recommended way to authenticate.

        Get one by exchanging a service account's access key pair at
        `POST /v1/oauth/token` with `grant_type=client_credentials`. It is the
        standard client-credentials grant, so any OAuth-aware library will
        obtain and refresh it for you.

        ```
        curl -s -u "$KEY_ID:$SECRET" -d grant_type=client_credentials \
          https://iam.basaltic.sh/v1/oauth/token
        ```

        Tokens last an hour by default. The same access key pair is separately
        your AWS SigV4 credential for the S3-compatible object endpoint, which
        speaks nothing else.
