  title: Amazon KMS Create Key and Describe
  summary: Create a new customer managed KMS key and read back its full metadata.
  description: >-
    Provisions a new customer managed KMS key in the caller's account and Region
    and then describes the freshly created key to confirm its state, ARN, and
    usage. The KeyId returned from creation is chained into the describe call so
    the workflow can verify the key landed in the expected state before any other
    automation depends on it. Each step spells out its request inline, including
    the AWS JSON protocol X-Amz-Target header, so the flow can be read and
    executed without opening the underlying OpenAPI description.
