// 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.
