  title: Amazon Kinesis Deregister Consumer and Delete Stream
  summary: Deregister an enhanced fan-out consumer, confirm the stream, then delete it.
  description: >-
    A clean teardown flow for a stream and its consumer. The workflow first
    deregisters the named enhanced fan-out consumer with
    DeregisterStreamConsumer, confirms the stream still exists and reads its ARN
    with DescribeStreamSummary, and then deletes the stream and all its data
    with DeleteStream. Each step inlines its AWS JSON protocol request,
    including the required X-Amz-Target header, so the teardown can be read and
    executed without opening the underlying OpenAPI description.
