// 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 identity pools (https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-identity.html)
// in Amazon Cognito 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 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 (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
// 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. 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:
//   - Using Web Identity Federation API Operations for Mobile Apps (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_providers_oidc_manual.html)
