The Amazon Resource Name (ARN) and the assumed role ID, which are identifiers that you
can use to refer to the resulting temporary security credentials. For example, you can
reference these credentials as a principal in a resource-based policy by using the ARN or
assumed role ID. The ARN and ID include the
RoleSessionName that you specified
when you called
The intended audience (also known as client ID) of the web identity token. This is traditionally the client identifier issued to the application that requested the web identity token.
The temporary security credentials, which include an access key ID, a secret access key, and a security token.
The size of the security token that STS API operations return is not fixed. We strongly recommend that you make no assumptions about the maximum size.
A percentage value that indicates the packed size of the session policies and session tags combined passed in the request. The request fails if the packed size is greater than 100 percent, which means the policies and tags exceeded the allowed space.
The issuing authority of the web identity token presented. For OpenID Connect ID
tokens, this contains the value of the
iss field. For OAuth 2.0 access tokens,
this contains the value of the
ProviderId parameter that was passed in the
The value of the source identity that is returned in the JSON web token (JWT) from the identity provider.
You can require users to set a source identity value when they assume a role. You do
this by using the
sts:SourceIdentity condition key in a role trust policy.
That way, actions that are taken with the role are associated with that user. After the
source identity is set, the value cannot be changed. It is present in the request for all
actions that are taken by the role and persists across chained
role sessions. You can configure your identity provider to use an attribute
associated with your users, like user name or email, as the source identity when calling
AssumeRoleWithWebIdentity. You do this by adding a claim to the JSON web
token. To learn more about OIDC tokens and claims, see Using Tokens with User Pools in the Amazon Cognito Developer Guide.
For more information about using source identity, see Monitor and control
actions taken with assumed roles in the
IAM User Guide.
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: =,.@-
The unique user identifier that is returned by the identity provider. This identifier is
associated with the
WebIdentityToken that was submitted with the
AssumeRoleWithWebIdentity call. The identifier is typically unique to the
user and the application that acquired the
identifier). For OpenID Connect ID tokens, this field contains the value returned by the
identity provider as the token's
sub (Subject) claim.
Contains the response to a successful AssumeRoleWithWebIdentity request, including temporary Amazon Web Services credentials that can be used to make Amazon Web Services requests.
