Update queue attributes
The name, the kind, and content_based_deduplication are
immutable. The first two are the CRN and the delivery contract;
flipping the third would change how sends already accepted inside
the live deduplication window are interpreted.
Changing kms_key re-keys the queue. kms_key: null restores the platform key; omitting kms_key leaves it unchanged. Messages already on it
keep the key they were sealed with, so they stay readable under
the old key until they drain — which is the point of rotating
away from a key you no longer trust.

}Requires the IAM action
queue:UpdateQueue. See QUEUE permissions for the full list, what each one covers, and an example policy.Authorizations
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.
