// Returns a set of temporary security credentials for users who have been
// authenticated in a mobile or web application with a web identity 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
// (https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-identity.html).
// 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
// (http://aws.amazon.com/sdkforios/) and the Amazon Web Services SDK for Android
// Developer Guide (http://aws.amazon.com/sdkforandroid/) 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 Overview
// (https://docs.aws.amazon.com/mobile/sdkforandroid/developerguide/cognito-auth.html#d0e840)
// in Amazon Web Services SDK for Android Developer Guide and Amazon Cognito
// Overview
// (https://docs.aws.amazon.com/mobile/sdkforios/developerguide/cognito-auth.html#d0e664)
// in the Amazon Web Services SDK for iOS Developer Guide. 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
// (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. 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 View the Maximum Session Duration Setting for a Role
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html#id_roles_use_view-role-max-session)
// 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
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html) 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
// (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. 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
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session)
// 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
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_session-tags.html) 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
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_iam-limits.html#reference_iam-limits-entity-length)
// in the IAM User Guide. An Amazon Web Services conversion compresses the passed
// session policies 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. 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
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/tutorial_attribute-based-access-control.html)
// 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
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_session-tags.html#id_session-tags_role-chaining)
// 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
// (http://openid.net/specs/openid-connect-core-1_0.html#Claims) 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
// (http://openid.net/specs/openid-connect-core-1_0.html#SubjectIDTypes). For more
// information about how to use web identity federation and the
// AssumeRoleWithWebIdentity API, see the following resources:
