    #   @param [Hash] options
    #   @option options [required, Aws::CredentialProvider] :credentials
    #     Your AWS credentials. This can be an instance of any one of the
    #     following classes:
    #
    #     * `Aws::Credentials` - Used for configuring static, non-refreshing
    #       credentials.
    #
    #     * `Aws::InstanceProfileCredentials` - Used for loading credentials
    #       from an EC2 IMDS on an EC2 instance.
    #
    #     * `Aws::SharedCredentials` - Used for loading credentials from a
    #       shared file, such as `~/.aws/config`.
    #
    #     * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
    #
    #     When `:credentials` are not configured directly, the following
    #     locations will be searched for credentials:
    #
    #     * `Aws.config[:credentials]`
    #     * The `:access_key_id`, `:secret_access_key`, and `:session_token` options.
    #     * ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    #     * `~/.aws/credentials`
    #     * `~/.aws/config`
    #     * EC2 IMDS instance profile - When used by default, the timeouts are
    #       very aggressive. Construct and pass an instance of
    #       `Aws::InstanceProfileCredentails` to enable retries and extended
    #       timeouts.
    #
    #   @option options [required, String] :region
    #     The AWS region to connect to.  The configured `:region` is

    #
    #   @option options [String] :session_token
    #
    #   @option options [Boolean] :simple_json (false)
    #     Disables request parameter conversion, validation, and formatting.
    #     Also disable response data type conversions. This option is useful
    #     when you want to ensure the highest level of performance by
    #     avoiding overhead of walking request parameters and response data
    #     structures.
    #
    #     When `:simple_json` is enabled, the request parameters hash must
    #     be formatted exactly as the DynamoDB API expects.
    #
    #   @option options [Boolean] :stub_responses (false)
    #     Causes the client to return stubbed responses. By default
    #     fake responses are generated and returned. You can specify

    #     {ClientStubs#stub_responses}. See {ClientStubs} for more information.
    #
    #     ** Please note ** When response stubbing is enabled, no HTTP
    #     requests are made, and retries are disabled.
    #
    #   @option options [Boolean] :validate_params (true)
    #     When `true`, request parameters are validated before
    #     sending the request.
    #

    #     number of seconds to wait for response data.  This value can
    #     safely be set
    #     per-request on the session yeidled by {#session_for}.
    #
    #   @option options [Float] :http_idle_timeout (5) The number of
    #     seconds a connection is allowed to sit idble before it is
    #     considered stale.  Stale connections are closed and removed
    #     from the pool before making a request.
    #
    #   @option options [Float] :http_continue_timeout (1) The number of
    #     seconds to wait for a 100-continue response before sending the
    #     request body.  This option has no effect unless the request has
    #     "Expect" header set to "100-continue".  Defaults to `nil` which
    #     disables this behaviour.  This value can safely be set per
    #     request on the session yeidled by {#session_for}.
    #
    #   @option options [Boolean] :http_wire_trace (false) When `true`,
    #     HTTP debug output will be sent to the `:logger`.
    #
    #   @option options [Boolean] :ssl_verify_peer (true) When `true`,
    #     SSL peer certificates are verified when establishing a
    #     connection.
    #
    #   @option options [String] :ssl_ca_bundle Full path to the SSL
    #     certificate authority bundle file that should be used when
    #     verifying peer certificates.  If you do not pass
    #     `:ssl_ca_bundle` or `:ssl_ca_directory` the the system default
    #     will be used if available.
    #
    #   @option options [String] :ssl_ca_directory Full path of the
    #     directory that contains the unbundled SSL certificate
    #     authority files for verifying peer certificates.  If you do

    # Transfer Protocol (SFTP) server you updated.
    #
    # @option params [Types::EndpointDetails] :endpoint_details
    #   The virtual private cloud (VPC) endpoint settings that are configured
    #   for your SFTP server. With a VPC endpoint, your SFTP server isn't
    #   accessible over the public internet.
    #
    # @option params [String] :endpoint_type
    #   The type of endpoint that you want your SFTP server to connect to. You

    #   cloud (VPC) endpoint. With a VPC endpoint, your SFTP server isn't
    #   accessible over the public internet.
    #
    # @option params [String] :host_key
    #   The RSA private key as generated by `ssh-keygen -N "" -f
    #   my-new-server-key`.
    #
    #   If you aren't planning to migrate existing users from an existing
    #   SFTP server to a new AWS SFTP server, don't update the host key.
    #   Accidentally changing a server's host key can be disruptive.
    #

    # @option params [Types::IdentityProviderDetails] :identity_provider_details
    #   This response parameter is an array containing all of the information
    #   required to call a customer's authentication API method.
    #
    # @option params [String] :logging_role
    #   A value that changes the AWS Identity and Access Management (IAM) role
    #   that allows Amazon S3 events to be logged in Amazon CloudWatch,
    #   turning logging on or off.
    #
    # @option params [required, String] :server_id
    #   A system-assigned unique identifier for an SFTP server instance that
    #   the user account is assigned to.

    #
    # @option params [String] :home_directory
    #   A parameter that specifies the landing directory (folder) for a user
    #   when they log in to the server using their client. An example is
    #   `/home/username `.
    #
    # @option params [String] :policy
    #   Allows you to supply a scope-down policy for your user so you can use
    #   the same AWS Identity and Access Management (IAM) role across multiple
    #   users. The policy scopes down user access to portions of your Amazon
    #   S3 bucket. Variables you can use inside this policy include
    #   `$\{Transfer:UserName\}`, `$\{Transfer:HomeDirectory\}`, and
    #   `$\{Transfer:HomeBucket\}`.
    #
    #   <note markdown="1"> For scope-down policies, AWS Transfer for SFTP stores the policy as a
    #   JSON blob, instead of the Amazon Resource Name (ARN) of the policy.
    #   You save the policy as a JSON blob and pass it in the `Policy`
    #   argument.
    #
    #    For an example of a scope-down policy, see
    #   "https://docs.aws.amazon.com/transfer/latest/userguide/users.html#users-policies-scope-down"&gt;Creating
    #   a Scope-Down Policy.

    #
    # @option params [String] :role
    #   The IAM role that controls your user's access to your Amazon S3
    #   bucket. The policies attached to this role will determine the level of
    #   access you want to provide your users when transferring files into and
    #   out of your Amazon S3 bucket or buckets. The IAM role should also
    #   contain a trust relationship that allows the Secure File Transfer
    #   Protocol (SFTP) server to access your resources when servicing your
    #   SFTP user's transfer requests.
    #
    # @option params [required, String] :server_id

    #
    # @option params [required, String] :user_name
    #   A unique string that identifies a user and is associated with a server
    #   as specified by the `ServerId`. This is the string that will be used
    #   by your user when they log in to your SFTP server. This user name is a
    #   minimum of 3 and a maximum of 32 characters long. The following are
    #   valid characters: a-z, A-Z, 0-9, underscore, and hyphen. The user name
    #   can't start with a hyphen.
