    #   @param [Hash] options
    #
    #   @option options [Array<Seahorse::Client::Plugin>] :plugins ([]])
    #     A list of plugins to apply to the client. Each plugin is either a
    #     class name or an instance of a plugin class.
    #
    #   @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::SharedCredentials` - Used for loading static credentials from a
    #       shared file, such as `~/.aws/config`.
    #
    #     * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
    #
    #     * `Aws::AssumeRoleWebIdentityCredentials` - Used when you need to
    #       assume a role after providing credentials via the web.
    #
    #     * `Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an
    #       access token generated from `aws login`.
    #
    #     * `Aws::ProcessCredentials` - Used for loading credentials from a
    #       process that outputs to stdout.
    #
    #     * `Aws::InstanceProfileCredentials` - Used for loading credentials
    #       from an EC2 IMDS on an EC2 instance.
    #
    #     * `Aws::ECSCredentials` - Used for loading credentials from
    #       instances running in ECS.
    #
    #     * `Aws::CognitoIdentityCredentials` - Used for loading credentials
    #       from the Cognito Identity service.
    #
    #     When `:credentials` are not configured directly, the following
    #     locations will be searched for credentials:
    #
    #     * `Aws.config[:credentials]`
    #     * The `:access_key_id`, `:secret_access_key`, `:session_token`, and
    #       `:account_id` options.
    #     * ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY'],
    #       ENV['AWS_SESSION_TOKEN'], and ENV['AWS_ACCOUNT_ID']
    #     * `~/.aws/credentials`
    #     * `~/.aws/config`
    #     * EC2/ECS IMDS instance profile - When used by default, the timeouts
    #       are very aggressive. Construct and pass an instance of
    #       `Aws::InstanceProfileCredentials` or `Aws::ECSCredentials` to
    #       enable retries and extended timeouts. Instance profile credential
    #       fetching can be disabled by setting ENV['AWS_EC2_METADATA_DISABLED']
    #       to true.
    #
    #   @option options [required, String] :region

    #
    #   @option options [String, URI::HTTPS, URI::HTTP] :endpoint
    #     Normally you should not configure the `:endpoint` option
    #     directly. This is normally constructed from the `:region`
    #     option. Configuring `:endpoint` is normally reserved for
    #     connecting to test or custom endpoints. The endpoint should
    #     be a URI formatted like:

    #     4 times. Used in `standard` and `adaptive` retry modes.
    #
    #   @option options [String] :profile ("default")
    #     Used when loading credentials from the shared credentials file
    #     at HOME/.aws/credentials.  When not specified, 'default' is used.
    #
    #   @option options [String] :request_checksum_calculation ("when_supported")
    #     Determines when a checksum will be calculated for request payloads. Values are:
    #
    #     * `when_supported` - (default) When set, a checksum will be
    #       calculated for all request payloads of operations modeled with the

    #
    #   @option options [Integer] :retry_limit (3)
    #     The maximum number of times to retry failed requests.  Only
    #     ~ 500 level server errors and certain ~ 400 level client errors
    #     are retried.  Generally, these are throttling errors, data
    #     checksum errors, networking errors, timeout errors, auth errors,
    #     endpoint discovery, and errors from expired credentials.
    #     This option is only used in the `legacy` retry mode.
    #
    #   @option options [Integer] :retry_max_delay (0)
    #     The maximum number of seconds to delay between retries (0 for no limit)
    #     used by the default backoff function. This option is only used in the

    #       This includes support for retry quotas, which limit the number of
    #       unsuccessful retries a client can make.
    #
    #     * `adaptive` - An experimental retry mode that includes all the
    #       functionality of `standard` mode along with automatic client side
    #       throttling.  This is a provisional mode that may change behavior
    #       in the future.
    #
    #   @option options [String] :sdk_ua_app_id
    #     A unique and opaque application ID that is appended to the
    #     User-Agent header as app/sdk_ua_app_id. It should have a

    #
    #   @option options [String] :sts_regional_endpoints ("regional")
    #     Passing in 'regional' to enable regional endpoint for STS for all supported
    #     regions (except 'aws-global'). Using 'legacy' mode will force all legacy
    #     regions to resolve to the STS global endpoint.
    #
    #   @option options [Boolean] :stub_responses (false)
    #     Causes the client to return stubbed responses. By default
    #     fake responses are generated and returned. You can specify
    #     the response data to return or errors to raise by calling
    #     {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 [Aws::Telemetry::TelemetryProviderBase] :telemetry_provider (Aws::Telemetry::NoOpTelemetryProvider)
    #     Allows you to provide a telemetry provider, which is used to
    #     emit telemetry data. By default, uses `NoOpTelemetryProvider` which

    #
    #     * OpenTelemetry (OTel) - To use the OTel provider, install and require the
    #     `opentelemetry-sdk` gem and then, pass in an instance of a
    #     `Aws::Telemetry::OTelProvider` for telemetry provider.
    #
    #   @option options [Aws::TokenProvider] :token_provider
    #     A Bearer Token Provider. This can be an instance of any one of the

    #       tokens.
    #
    #     * `Aws::SSOTokenProvider` - Used for loading tokens from AWS SSO using an
    #       access token generated from `aws login`.
    #
    #     When `:token_provider` is not configured directly, the `Aws::TokenProviderChain`
    #     will be used to search for tokens configured for your profile in shared configuration files.
    #
    #   @option options [Boolean] :use_dualstack_endpoint
    #     When set to `true`, dualstack enabled endpoints (with `.aws` TLD)
    #     will be used if available.
    #
    #   @option options [Boolean] :use_fips_endpoint
    #     When set to `true`, fips compatible endpoints will be used if available.

    #   @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.
    #
    #   @option options [Float] :http_idle_timeout (5)
    #     The number of seconds a connection is allowed to sit idle before it
    #     is considered stale.  Stale connections are closed and removed from the
    #     pool before making a request.
    #
    #   @option options [Float] :http_open_timeout (15)
    #     The default number of seconds to wait for response data.

    #   @option options [Proc] :on_chunk_received
    #     When a Proc object is provided, it will be used as callback when each chunk
    #     of the response body is received. It provides three arguments: the chunk,
    #     the number of bytes received, and the total number of
    #     bytes in the response (or nil if the server did not send a `content-length`).
    #
    #   @option options [Proc] :on_chunk_sent
    #     When a Proc object is provided, it will be used as callback when each chunk
    #     of the request body is sent. It provides three arguments: the chunk,

    # @!group API Operations

    # Returns a set of temporary security credentials that you can use to
    # access Amazon Web Services resources. These temporary credentials
    # consist of an access key ID, a secret access key, and a security
    # token. Typically, you use `AssumeRole` within your account or for
    # cross-account access. For a comparison of `AssumeRole` with other API
    # operations that produce temporary credentials, see [Requesting
    # Temporary Security Credentials][1] and [Compare STS credentials][2] in
    # the *IAM User Guide*.
    #
    # **Permissions**
    #
    # The temporary security credentials created by `AssumeRole` can be used
    # to make API calls to any Amazon Web Services service with the
    # following exception: You cannot call the Amazon Web Services STS
    # `GetFederationToken` or `GetSessionToken` API operations.
    #
    # (Optional) You can pass inline or managed session policies to this
    # operation. You can pass a single JSON policy document to use as an
    # inline session policy. You can also specify up to 10 managed policy
    # Amazon Resource Names (ARNs) to use as managed session policies. The
    # plaintext that you use for both inline and managed session policies
    # can't exceed 2,048 characters. Passing policies to this operation
    # returns new temporary credentials. The resulting session's
    # permissions are the intersection of the role's identity-based policy
    # and the session policies. You can use the role's temporary
    # credentials in subsequent Amazon Web Services API calls to access
    # resources in the account that owns the role. You cannot use session
    # policies to grant more permissions than those allowed by the
    # identity-based policy of the role that is being assumed. For more
    # information, see [Session Policies][3] in the *IAM User Guide*.
    #
    # When you create a role, you create two policies: a role trust policy
    # that specifies *who* can assume the role, and a permissions policy
    # that specifies *what* can be done with the role. You specify the
    # trusted principal that is allowed to assume the role in the role trust
    # policy.
    #
    # To assume a role from a different account, your Amazon Web Services
    # account must be trusted by the role. The trust relationship is defined
    # in the role's trust policy when the role is created. That trust
    # policy states which accounts are allowed to delegate that access to
    # users in the account.
    #
    # A user who wants to access a role in a different account must also
    # have permissions that are delegated from the account administrator.
    # The administrator must attach a policy that allows the user to call
    # `AssumeRole` for the ARN of the role in the other account.
    #
    # To allow a user to assume a role in the same account, you can do
    # either of the following:
    #
    # * Attach a policy to the user that allows the user to call
    #   `AssumeRole` (as long as the role's trust policy trusts the
    #   account).
    #
    # * Add the user as a principal directly in the role's trust policy.
    #
    # You can do either because the role’s trust policy acts as an IAM
    # resource-based policy. When a resource-based policy grants access to a
    # principal in the same account, no additional identity-based policy is
    # required. For more information about trust policies and resource-based
    # policies, see [IAM Policies][4] in the *IAM User Guide*.
    #
    # **Tags**
    #
    # (Optional) You can pass tag key-value pairs to your session. These
    # tags are called session tags. For more information about session tags,
    # see [Passing Session Tags in STS][5] in the *IAM User Guide*.
    #
    # An administrator must grant you the permissions necessary to pass
    # session tags. The administrator can also create granular permissions
    # to allow you to pass only specific session tags. For more information,
    # see [Tutorial: Using Tags for Attribute-Based Access Control][6] in
    # the *IAM User Guide*.
    #
    # You can set the session tags as transitive. Transitive tags persist
    # during role chaining. For more information, see [Chaining Roles with
    # Session Tags][7] in the *IAM User Guide*.
    #
    # **Using MFA with AssumeRole**
    #
    # (Optional) You can include multi-factor authentication (MFA)
    # information when you call `AssumeRole`. This is useful for
    # cross-account scenarios to ensure that the user that assumes the role
    # has been authenticated with an Amazon Web Services MFA device. In that
    # scenario, the trust policy of the role being assumed includes a
    # condition that tests for MFA authentication. If the caller does not
    # include valid MFA information, the request to assume the role is
    # denied. The condition in a trust policy that tests for MFA
    # authentication might look like the following example.
    #
    # `"Condition": {"Bool": {"aws:MultiFactorAuthPresent": true}}`
    #
    # For more information, see [Configuring MFA-Protected API Access][8] in
    # the *IAM User Guide* guide.
    #
    # To use MFA with `AssumeRole`, you pass values for the `SerialNumber`
    # and `TokenCode` parameters. The `SerialNumber` value identifies the
    # user's hardware or virtual MFA device. The `TokenCode` is the
    # time-based one-time password (TOTP) that the MFA device produces.

    #   An identifier for the assumed role session.
    #
    #   Use the role session name to uniquely identify a session when the same
    #   role is assumed by different principals or for different reasons. In
    #   cross-account scenarios, the role session name is visible to, and can
    #   be logged by the account that owns the role. The role session name is
    #   also used in the ARN of the assumed role principal. This means that
    #   subsequent cross-account API requests that use the temporary security
    #   credentials will expose the role session name to the external account
    #   in their CloudTrail logs.
    #
    #   For security purposes, administrators can view this field in
    #   [CloudTrail logs][1] to help identify who performed an action in
    #   Amazon Web Services. Your administrator might require that you specify
    #   your user name as the session name when you assume the role. For more

    # @option params [String] :policy
    #   An IAM policy in JSON format that you want to use as an inline session

    #
    # @option params [Integer] :duration_seconds
    #   The duration, in seconds, of the role session. The value specified can
    #   range from 900 seconds (15 minutes) up to the maximum session duration
    #   set for the role. The maximum session duration setting can have a
    #   value from 1 hour to 12 hours. If you specify a value higher than this
    #   setting or the administrator setting (whichever is lower), the
    #   operation fails. For example, if you specify a session duration of 12
    #   hours, but your administrator set the maximum session duration to 6
    #   hours, your operation fails.
    #
    #   Role chaining limits your Amazon Web Services CLI or Amazon Web
    #   Services API role session to a maximum of one hour. When you use the
    #   `AssumeRole` API operation to assume a role, you can specify the
    #   duration of your role session with the `DurationSeconds` parameter.
    #   You can specify a parameter value of up to 43200 seconds (12 hours),
    #   depending on the maximum session duration setting for your role.
    #   However, if you assume a role using role chaining and provide a
    #   `DurationSeconds` parameter value greater than one hour, the operation
    #   fails. To learn how to view the maximum value for your role, see

    #
    #   You can pass a session tag with the same key as a tag that is already

    #   with the same key.
    #
    #   Tag key–value pairs are not case sensitive, but case is preserved.
    #   This means that you cannot have separate `Department` and `department`
    #   tag keys. Assume that the role has the `Department`=`Marketing` tag
    #   and you pass the `department`=`engineering` session tag. `Department`
    #   and `department` are not saved as separate tags, and the session tag
    #   passed in the request takes precedence over the role tag.
    #
    #   Additionally, if you used temporary credentials to perform this
    #   operation, the new session inherits any transitive session tags from
    #   the calling session. If you pass a session tag with the same key as an

    #   belongs provided you with an external ID, then provide that value in
    #   the `ExternalId` parameter. This value can be any string, such as a
    #   passphrase or account number. A cross-account role is usually set up
    #   to trust everyone in an account. Therefore, the administrator of the
    #   trusting account might send an external ID to the administrator of the
    #   trusted account. That way, only someone with the ID can assume the

    # Returns a set of temporary security credentials for users who have
    # been authenticated via a SAML authentication response. This operation
    # provides a mechanism for tying an enterprise identity store or
    # directory to role-based Amazon Web Services access without
    # user-specific credentials or configuration. For a comparison of
    # `AssumeRoleWithSAML` with the other API operations that produce
    # temporary credentials, see [Requesting Temporary Security
    # Credentials][1] and [Compare STS credentials][2] in the *IAM User
    # Guide*.
    #
    # The temporary security credentials returned by this operation consist
    # of an access key ID, a secret access key, and a security token.
    # Applications can use these temporary security credentials to sign
    # calls to Amazon Web Services services.
    #
    # **Session Duration**
    #
    # By default, the temporary security credentials created by
    # `AssumeRoleWithSAML` last for one hour. However, you can use the
    # optional `DurationSeconds` parameter to specify the duration of your
    # session. Your role session lasts for the duration that you specify, or
    # until the time specified in the SAML authentication response's
    # `SessionNotOnOrAfter` value, whichever is shorter. You can provide a
    # `DurationSeconds` value from 900 seconds (15 minutes) up to the
    # maximum session duration setting for the role. This setting can have a
    # value from 1 hour to 12 hours. To learn how to view the maximum value
    # for your role, see [View the Maximum Session Duration Setting for a
    # Role][3] in the *IAM User Guide*. The maximum session duration limit
    # applies when you use the `AssumeRole*` API operations or the
    # `assume-role*` CLI commands. However the limit does not apply when you
    # use those operations to create a console URL. For more information,
    # see [Using IAM Roles][4] in the *IAM User Guide*.
    #
    # <note markdown="1"> [Role chaining][5] limits your CLI or Amazon Web Services API role
    # session to a maximum of one hour. When you use the `AssumeRole` API
    # operation to assume a role, you can specify the duration of your role
    # session with the `DurationSeconds` parameter. You can specify a
    # parameter value of up to 43200 seconds (12 hours), depending on the
    # maximum session duration setting for your role. However, if you assume
    # a role using role chaining and provide a `DurationSeconds` parameter
    # value greater than one hour, the operation fails.
    #
    #  </note>
    #
    # **Permissions**
    #
    # The temporary security credentials created by `AssumeRoleWithSAML` can
    # be used to make API calls to any Amazon Web Services service with the
    # following exception: you cannot call the STS `GetFederationToken` or
    # `GetSessionToken` API operations.
    #
    # (Optional) You can pass inline or managed [session policies][6] to
    # this operation. You can pass a single JSON policy document to use as
    # an inline session policy. You can also specify up to 10 managed policy
    # Amazon Resource Names (ARNs) to use as managed session policies. The
    # plaintext that you use for both inline and managed session policies
    # can't exceed 2,048 characters. Passing policies to this operation
    # returns new temporary credentials. The resulting session's
    # permissions are the intersection of the role's identity-based policy
    # and the session policies. You can use the role's temporary
    # credentials in subsequent Amazon Web Services API calls to access
    # resources in the account that owns the role. You cannot use session
    # policies to grant more permissions than those allowed by the
    # identity-based policy of the role that is being assumed. For more
    # information, see [Session Policies][6] in the *IAM User Guide*.
    #
    # Calling `AssumeRoleWithSAML` does not require the use of Amazon Web
    # Services security credentials. The identity of the caller is validated
    # by using keys in the metadata document that is uploaded for the SAML
    # provider entity for your identity provider.
    #
    # Calling `AssumeRoleWithSAML` can result in an entry in your CloudTrail
    # logs. The entry includes the value in the `NameID` element of the SAML
    # assertion. We recommend that you use a `NameIDType` that is not
    # associated with any personally identifiable information (PII). For
    # example, you could instead use the persistent identifier
    # (`urn:oasis:names:tc:SAML:2.0:nameid-format:persistent`).
    #
    # **Tags**
    #
    # (Optional) You can configure your IdP to pass attributes into your
    # SAML assertion as session tags. Each session tag consists of a key
    # name and an associated value. For more information about session tags,
    # see [Passing Session Tags in STS][7] in the *IAM User Guide*.
    #
    # You can pass up to 50 session tags. The plaintext session tag keys
    # can’t exceed 128 characters and the values can’t exceed 256
    # characters. For these and additional limits, see [IAM and STS
    # Character Limits][8] in the *IAM User Guide*.
    #
    # <note markdown="1"> An Amazon Web Services conversion compresses the passed inline session
    # policy, managed policy ARNs, and session tags into a packed binary
    # format that has a separate limit. Your request can fail for this limit
    # even if your plaintext meets the other requirements. The
    # `PackedPolicySize` response element indicates by percentage how close
    # the policies and tags for your request are to the upper size limit.
    #
    #  </note>
    #
    # You can pass a session tag with the same key as a tag that is attached
    # to the role. When you do, session tags override the role's tags with
    # the same key.
    #
    # An administrator must grant you the permissions necessary to pass
    # session tags. The administrator can also create granular permissions
    # to allow you to pass only specific session tags. For more information,
    # see [Tutorial: Using Tags for Attribute-Based Access Control][9] in
    # the *IAM User Guide*.
    #
    # You can set the session tags as transitive. Transitive tags persist
    # during role chaining. For more information, see [Chaining Roles with
    # Session Tags][10] in the *IAM User Guide*.
    #
    # **SAML Configuration**
    #
    # Before your application can call `AssumeRoleWithSAML`, you must
    # configure your SAML identity provider (IdP) to issue the claims
    # required by Amazon Web Services. Additionally, you must use Identity
    # and Access Management (IAM) to create a SAML provider entity in your
    # Amazon Web Services account that represents your identity provider.
    # You must also create an IAM role that specifies this SAML provider in
    # its trust policy.
    #

    # Returns a set of temporary security credentials for users who have

    # provider. Example providers include the OAuth 2.0 providers Login with
    # Amazon and Facebook, or any OpenID Connect-compatible identity
    # provider such as Google or [Amazon Cognito federated identities][1].
    #
    # <note markdown="1"> For mobile applications, we recommend that you use Amazon Cognito. You
    # can use Amazon Cognito with the [Amazon Web Services SDK for iOS
    # Developer Guide][2] and the [Amazon Web Services SDK for Android
    # Developer Guide][3] to uniquely identify a user. You can also supply
    # the user with a consistent identity throughout the lifetime of an
    # application.
    #
    #  To learn more about Amazon Cognito, see [Amazon Cognito identity
    # pools][1] in *Amazon Cognito Developer Guide*.
    #
    #  </note>
    #
    # Calling `AssumeRoleWithWebIdentity` does not require the use of Amazon
    # Web Services security credentials. Therefore, you can distribute an
    # application (for example, on mobile devices) that requests temporary
    # security credentials without including long-term Amazon Web Services
    # credentials in the application. You also don't need to deploy
    # server-based proxy services that use long-term Amazon Web Services
    # credentials. Instead, the identity of the caller is validated by using
    # a token from the web identity provider. For a comparison of
    # `AssumeRoleWithWebIdentity` with the other API operations that produce
    # temporary credentials, see [Requesting Temporary Security
    # Credentials][4] and [Compare STS credentials][5] in the *IAM User
    # Guide*.
    #
    # The temporary security credentials returned by this API consist of an
    # access key ID, a secret access key, and a security token. Applications
    # can use these temporary security credentials to sign calls to Amazon
    # Web Services service API operations.
    #
    # **Session Duration**
    #
    # By default, the temporary security credentials created by
    # `AssumeRoleWithWebIdentity` last for one hour. However, you can use
    # the optional `DurationSeconds` parameter to specify the duration of
    # your session. You can provide a value from 900 seconds (15 minutes) up
    # to the maximum session duration setting for the role. This setting can
    # have a value from 1 hour to 12 hours. To learn how to view the maximum
    # value for your role, see [Update the maximum session duration for a
    # role ][6] in the *IAM User Guide*. The maximum session duration limit
    # applies when you use the `AssumeRole*` API operations or the
    # `assume-role*` CLI commands. However the limit does not apply when you
    # use those operations to create a console URL. For more information,
    # see [Using IAM Roles][7] in the *IAM User Guide*.
    #
    # **Permissions**
    #
    # The temporary security credentials created by
    # `AssumeRoleWithWebIdentity` can be used to make API calls to any
    # Amazon Web Services service with the following exception: you cannot
    # call the STS `GetFederationToken` or `GetSessionToken` API operations.
    #
    # (Optional) You can pass inline or managed [session policies][8] to
    # this operation. You can pass a single JSON policy document to use as
    # an inline session policy. You can also specify up to 10 managed policy
    # Amazon Resource Names (ARNs) to use as managed session policies. The
    # plaintext that you use for both inline and managed session policies
    # can't exceed 2,048 characters. Passing policies to this operation
    # returns new temporary credentials. The resulting session's
    # permissions are the intersection of the role's identity-based policy
    # and the session policies. You can use the role's temporary
    # credentials in subsequent Amazon Web Services API calls to access
    # resources in the account that owns the role. You cannot use session
    # policies to grant more permissions than those allowed by the
    # identity-based policy of the role that is being assumed. For more
    # information, see [Session Policies][8] in the *IAM User Guide*.
    #
    # **Tags**
    #
    # (Optional) You can configure your IdP to pass attributes into your web
    # identity token as session tags. Each session tag consists of a key
    # name and an associated value. For more information about session tags,
    # see [Passing Session Tags in STS][9] in the *IAM User Guide*.
    #
    # You can pass up to 50 session tags. The plaintext session tag keys
    # can’t exceed 128 characters and the values can’t exceed 256
    # characters. For these and additional limits, see [IAM and STS
    # Character Limits][10] in the *IAM User Guide*.
    #
    # <note markdown="1"> An Amazon Web Services conversion compresses the passed inline session
    # policy, managed policy ARNs, and session tags into a packed binary
    # format that has a separate limit. Your request can fail for this limit
    # even if your plaintext meets the other requirements. The
    # `PackedPolicySize` response element indicates by percentage how close
    # the policies and tags for your request are to the upper size limit.
    #
    #  </note>
    #
    # You can pass a session tag with the same key as a tag that is attached
    # to the role. When you do, the session tag overrides the role tag with
    # the same key.
    #
    # An administrator must grant you the permissions necessary to pass
    # session tags. The administrator can also create granular permissions
    # to allow you to pass only specific session tags. For more information,
    # see [Tutorial: Using Tags for Attribute-Based Access Control][11] in
    # the *IAM User Guide*.
    #
    # You can set the session tags as transitive. Transitive tags persist
    # during role chaining. For more information, see [Chaining Roles with
    # Session Tags][12] in the *IAM User Guide*.
    #
    # **Identities**
    #
    # Before your application can call `AssumeRoleWithWebIdentity`, you must
    # have an identity token from a supported identity provider and create a
    # role that the application can assume. The role that your application
    # assumes must trust the identity provider that is associated with the
    # identity token. In other words, the identity provider must be
    # specified in the role's trust policy.
    #
    # Calling `AssumeRoleWithWebIdentity` can result in an entry in your
    # CloudTrail logs. The entry includes the [Subject][13] of the provided
    # web identity token. We recommend that you avoid using any personally
    # identifiable information (PII) in this field. For example, you could
    # instead use a GUID or a pairwise identifier, as [suggested in the OIDC
    # specification][14].
    #
    # For more information about how to use OIDC federation and the
    # `AssumeRoleWithWebIdentity` API, see the following resources:
    #
    # * [Using Web Identity Federation API Operations for Mobile Apps][15]
    #   and [Federation Through a Web-based Identity Provider][16].
    #
    # * [Amazon Web Services SDK for iOS Developer Guide][2] and [Amazon Web
    #   Services SDK for Android Developer Guide][3]. These toolkits contain
    #   sample apps that show how to invoke the identity providers. The
    #   toolkits then show how to use the information from these providers
    #   to get and use temporary security credentials.

    # @option params [required, String] :role_arn
    #   The Amazon Resource Name (ARN) of the role that the caller is
    #   assuming.
    #
    #   <note markdown="1"> Additional considerations apply to Amazon Cognito identity pools that
    #   assume [cross-account IAM roles][1]. The trust policies of these roles
    #   must accept the `cognito-identity.amazonaws.com` service principal and
    #   must contain the `cognito-identity.amazonaws.com:aud` condition key to
    #   restrict role assumption to users from your intended identity pools. A
    #   policy that trusts Amazon Cognito identity pools without this
    #   condition creates a risk that a user from an unintended identity pool
    #   can assume the role. For more information, see [ Trust policies for

    #   application will use are associated with that user. This session name
    #   is included as part of the ARN and assumed role ID in the
    #   `AssumedRoleUser` response element.
    #
    #   For security purposes, administrators can view this field in
    #   [CloudTrail logs][1] to help identify who performed an action in

    #   authenticating the user who is using your application with a web
    #   identity provider before the application makes an
    #   `AssumeRoleWithWebIdentity` call. Timestamps in the token must be
    #   formatted as either an integer or a long integer. Tokens must be

    #   (ES256, ES384, or ES512).
    #
    # @option params [String] :provider_id
    #   The fully qualified host component of the domain name of the OAuth 2.0

    #
    #   Currently `www.amazon.com` and `graph.facebook.com` are the only

    #
    # For example, if a user is not authorized to perform an operation that
    # he or she has requested, the request returns a
    # `Client.UnauthorizedOperation` response (an HTTP 403 response). Some
    # Amazon Web Services operations additionally return an encoded message

    # Returns a set of temporary security credentials (consisting of an

    # A typical use is in a proxy application that gets temporary security
    # credentials on behalf of distributed applications inside a corporate
    # network.
    #
    # You must call the `GetFederationToken` operation using the long-term
    # security credentials of an IAM user. As a result, this call is
    # appropriate in contexts where those credentials can be safeguarded,
    # usually in a server-based application. For a comparison of
    # `GetFederationToken` with the other API operations that produce
    # temporary credentials, see [Requesting Temporary Security
    # Credentials][1] and [Compare STS credentials][2] in the *IAM User
    # Guide*.
    #
    # Although it is possible to call `GetFederationToken` using the
    # security credentials of an Amazon Web Services account root user
    # rather than an IAM user that you create for the purpose of a proxy
    # application, we do not recommend it. For more information, see
    # [Safeguard your root user credentials and don't use them for everyday
    # tasks][3] in the *IAM User Guide*.
    #
    # <note markdown="1"> You can create a mobile-based or browser-based app that can
    # authenticate users using a web identity provider like Login with
    # Amazon, Facebook, Google, or an OpenID Connect-compatible identity
    # provider. In this case, we recommend that you use [Amazon Cognito][4]
    # or `AssumeRoleWithWebIdentity`. For more information, see [Federation
    # Through a Web-based Identity Provider][5] in the *IAM User Guide*.
    #
    #  </note>
    #
    # **Session duration**
    #
    # The temporary credentials are valid for the specified duration, from
    # 900 seconds (15 minutes) up to a maximum of 129,600 seconds (36
    # hours). The default session duration is 43,200 seconds (12 hours).
    # Temporary credentials obtained by using the root user credentials have
    # a maximum duration of 3,600 seconds (1 hour).
    #
    # **Permissions**
    #
    # You can use the temporary credentials created by `GetFederationToken`
    # in any Amazon Web Services service with the following exceptions:
    #
    # * You cannot call any IAM operations using the CLI or the Amazon Web
    #   Services API. This limitation does not apply to console sessions.
    #
    # * You cannot call any STS operations except `GetCallerIdentity`.
    #
    # You can use temporary credentials for single sign-on (SSO) to the
    # console.
    #
    # You must pass an inline or managed [session policy][6] to this
    # operation. You can pass a single JSON policy document to use as an
    # inline session policy. You can also specify up to 10 managed policy
    # Amazon Resource Names (ARNs) to use as managed session policies. The
    # plaintext that you use for both inline and managed session policies
    # can't exceed 2,048 characters.
    #
    # Though the session policy parameters are optional, if you do not pass
    # a policy, then the resulting federated user session has no
    # permissions. When you pass session policies, the session permissions
    # are the intersection of the IAM user policies and the session policies
    # that you pass. This gives you a way to further restrict the
    # permissions for a federated user. You cannot use session policies to
    # grant more permissions than those that are defined in the permissions
    # policy of the IAM user. For more information, see [Session
    # Policies][6] in the *IAM User Guide*. For information about using
    # `GetFederationToken` to create temporary security credentials, see
    # [GetFederationToken—Federation Through a Custom Identity Broker][7].
    #
    # You can use the credentials to access a resource that has a
    # resource-based policy. If that policy specifically references the
    # federated user session in the `Principal` element of the policy, the
    # session has the permissions allowed by the policy. These permissions
    # are granted in addition to the permissions granted by the session
    # policies.
    #
    # **Tags**
    #
    # (Optional) You can pass tag key-value pairs to your session. These are
    # called session tags. For more information about session tags, see
    # [Passing Session Tags in STS][8] in the *IAM User Guide*.
    #
    # <note markdown="1"> You can create a mobile-based or browser-based app that can
    # authenticate users using a web identity provider like Login with
    # Amazon, Facebook, Google, or an OpenID Connect-compatible identity
    # provider. In this case, we recommend that you use [Amazon Cognito][4]
    # or `AssumeRoleWithWebIdentity`. For more information, see [Federation
    # Through a Web-based Identity Provider][5] in the *IAM User Guide*.
    #
    #  </note>
    #
    # An administrator must grant you the permissions necessary to pass
    # session tags. The administrator can also create granular permissions
    # to allow you to pass only specific session tags. For more information,
    # see [Tutorial: Using Tags for Attribute-Based Access Control][9] in
    # the *IAM User Guide*.
    #
    # Tag key–value pairs are not case sensitive, but case is preserved.
    # This means that you cannot have separate `Department` and `department`
    # tag keys. Assume that the user that you are federating has the
    # `Department`=`Marketing` tag and you pass the
    # `department`=`engineering` session tag. `Department` and `department`
    # are not saved as separate tags, and the session tag passed in the
    # request takes precedence over the user tag.

    #   Tag key–value pairs are not case sensitive, but case is preserved.
    #   This means that you cannot have separate `Department` and `department`
    #   tag keys. Assume that the role has the `Department`=`Marketing` tag
    #   and you pass the `department`=`engineering` session tag. `Department`
    #   and `department` are not saved as separate tags, and the session tag

    # Returns a set of temporary credentials for an Amazon Web Services
    # account or IAM user. The credentials consist of an access key ID, a
    # secret access key, and a security token. Typically, you use
    # `GetSessionToken` if you want to use MFA to protect programmatic calls
    # to specific Amazon Web Services API operations like Amazon EC2
    # `StopInstances`.
    #
    # MFA-enabled IAM users must call `GetSessionToken` and submit an MFA
    # code that is associated with their MFA device. Using the temporary
    # security credentials that the call returns, IAM users can then make
    # programmatic calls to API operations that require MFA authentication.
    # An incorrect MFA code causes the API to return an access denied error.
    # For a comparison of `GetSessionToken` with the other API operations
    # that produce temporary credentials, see [Requesting Temporary Security
    # Credentials][1] and [Compare STS credentials][2] in the *IAM User
    # Guide*.
    #
    # <note markdown="1"> No permissions are required for users to perform this operation. The
    # purpose of the `sts:GetSessionToken` operation is to authenticate the
    # user using MFA. You cannot use policies to control authentication
    # operations. For more information, see [Permissions for
    # GetSessionToken][3] in the *IAM User Guide*.
    #
    #  </note>
    #
    # **Session Duration**
    #
    # The `GetSessionToken` operation must be called by using the long-term
    # Amazon Web Services security credentials of an IAM user. Credentials
    # that are created by IAM users are valid for the duration that you
    # specify. This duration can range from 900 seconds (15 minutes) up to a
    # maximum of 129,600 seconds (36 hours), with a default of 43,200
    # seconds (12 hours). Credentials based on account credentials can range
    # from 900 seconds (15 minutes) up to 3,600 seconds (1 hour), with a
    # default of 1 hour.
    #
    # **Permissions**
    #
    # The temporary security credentials created by `GetSessionToken` can be
    # used to make API calls to any Amazon Web Services service with the
    # following exceptions:
    #
    # * You cannot call any IAM API operations unless MFA authentication
    #   information is included in the request.
    #
    # * You cannot call any STS API *except* `AssumeRole` or
    #   `GetCallerIdentity`.
    #
    # The credentials that `GetSessionToken` returns are based on
    # permissions associated with the IAM user whose credentials were used
    # to call the operation. The temporary credentials have the same
    # permissions as the IAM user.
    #
    # <note markdown="1"> Although it is possible to call `GetSessionToken` using the security
    # credentials of an Amazon Web Services account root user rather than an
    # IAM user, we do not recommend it. If `GetSessionToken` is called using
    # root user credentials, the temporary credentials have root user
    # permissions. For more information, see [Safeguard your root user
    # credentials and don't use them for everyday tasks][4] in the *IAM
    # User Guide*
    #
    #  </note>

    # credentials, see [Temporary Credentials for Users in Untrusted
    # Environments][5] in the *IAM User Guide*.

    # @option params [Integer] :duration_seconds
    #   The duration, in seconds, that the credentials should remain valid.
    #   Acceptable durations for IAM user sessions range from 900 seconds (15
    #   minutes) to 129,600 seconds (36 hours), with 43,200 seconds (12 hours)
    #   as the default. Sessions for Amazon Web Services account owners are
    #   restricted to a maximum of 3,600 seconds (one hour). If the duration
    #   is longer than one hour, the session for Amazon Web Services account
    #   owners defaults to one hour.
    #
    # @option params [String] :serial_number
    #   The identification number of the MFA device that is associated with
    #   the IAM user who is making the `GetSessionToken` call. Specify this
    #   value if the IAM user has a policy that requires MFA authentication.
    #   The value is either the serial number for a hardware device (such as
    #   `GAHT12345678`) or an Amazon Resource Name (ARN) for a virtual device
    #   (such as `arn:aws:iam::123456789012:mfa/user`). You can find the
    #   device for an IAM user by going to the Amazon Web Services Management
    #   Console and viewing the user's security credentials.
    #
    #   The regex used to validate this parameter is a string of characters
    #   consisting of upper- and lower-case alphanumeric characters with no
    #   spaces. You can also include underscores or any of the following
    #   characters: =,.@:/-
    #
    # @option params [String] :token_code
    #   The value provided by the MFA device, if MFA is required. If any
    #   policy requires the IAM user to submit an MFA code, specify this
    #   value. If MFA authentication is required, the user must provide a code
    #   when requesting a set of temporary security credentials. A user who
    #   fails to provide the code receives an "access denied" response when
    #   requesting resources that require MFA authentication.
    #
    #   The format for this parameter, as described by its regex pattern, is a
