 // Returns a set of temporary security credentials (consisting of an access key ID,
 // a secret access key, and a security token) for a federated user. 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 safely stored, 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
 // (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html)
 // and Comparing the Amazon Web Services STS API operations
 // (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#stsapi_comparison)
 // in the IAM User Guide. 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 (http://aws.amazon.com/cognito/)
 // or AssumeRoleWithWebIdentity. For more information, see Federation Through a
 // Web-based Identity Provider
 // (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_assumerolewithwebidentity)
 // in the IAM User Guide. You can also call GetFederationToken using the security
 // credentials of an Amazon Web Services account root user, but we do not recommend
 // it. Instead, we recommend that you create an IAM user for the purpose of the
 // proxy application. Then attach a policy to the IAM user that limits federated
 // users to only the actions and resources that they need to access. For more
 // information, see IAM Best Practices
 // (https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html) in the
 // IAM User Guide. 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 Amazon Web Services account 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 except the following:
 //
 // * You cannot call any IAM
 // operations using the CLI or the Amazon Web Services API.
 //
 // * You cannot call any
 // STS operations except GetCallerIdentity.
 //
 // You must pass an inline or managed
 // session policy
 // (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session)
 // 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 policies 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
 // (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session)
 // in the IAM User Guide. For information about using GetFederationToken to create
 // temporary security credentials, see GetFederationToken—Federation Through a
 // Custom Identity Broker
 // (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_getfederationtoken).
 // 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
 // (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_session-tags.html) in the
 // IAM User Guide. 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 (http://aws.amazon.com/cognito/)
 // or AssumeRoleWithWebIdentity. For more information, see Federation Through a
 // Web-based Identity Provider
 // (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_assumerolewithwebidentity)
 // 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
 // (https://docs.aws.amazon.com/IAM/latest/UserGuide/tutorial_attribute-based-access-control.html)
 // 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.
