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.

sts_assume_role_with_web_identity(
RoleArn,
RoleSessionName,
WebIdentityToken,
ProviderId = NULL,
PolicyArns = NULL,
Policy = NULL,
DurationSeconds = NULL
)[required] The Amazon Resource Name (ARN) of the role that the caller is assuming.
[required] An identifier for the assumed role session. Typically, you pass the name
or identifier that is associated with the user who is using your
application. That way, the temporary security credentials that your
application will use are associated with that user. This session name is
included as part of the ARN and assumed role ID in the AssumedRoleUser
response element.
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: =,.@-
[required] The OAuth 2.0 access token or OpenID Connect ID token that is provided
by the identity provider. Your application must get this token by
authenticating the user who is using your application with a web
identity provider before the application makes an
assume_role_with_web_identity
call. Only tokens with RSA algorithms (RS256) are supported.
The fully qualified host component of the domain name of the OAuth 2.0 identity provider. Do not specify this value for an OpenID Connect identity provider.
Currently www.amazon.com and graph.facebook.com are the only
supported identity providers for OAuth 2.0 access tokens. Do not include
URL schemes and port numbers.
Do not specify this value for OpenID Connect ID tokens.
The Amazon Resource Names (ARNs) of the IAM managed policies that you want to use as managed session policies. The policies must exist in the same account as the role.
This parameter is optional. You can provide up to 10 managed policy ARNs. However, the plaintext that you use for both inline and managed session policies can't exceed 2,048 characters. For more information about ARNs, see Amazon Resource Names (ARNs) and Amazon Web Services Service Namespaces in the Amazon Web Services General Reference.
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.
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 in the IAM User Guide.
An IAM policy in JSON format that you want to use as an inline session policy.
This parameter is optional. 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 in the IAM User Guide.
The plaintext that you use for both inline and managed session policies
can't exceed 2,048 characters. The JSON policy characters can be any
ASCII character from the space character to the end of the valid
character list (U+0020 through U+00FF). It can also include the tab
(U+0009), linefeed (U+000A), and carriage return (U+000D) characters.
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.
The duration, in seconds, of the role session. The value can range 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. If you specify a value higher than this setting, the operation fails. For example, if you specify a session duration of 12 hours, but your administrator set the maximum session duration to 6 hours, your operation fails. To learn how to view the maximum value for your role, see View the Maximum Session Duration Setting for a Role in the IAM User Guide.
By default, the value is set to 3600 seconds.
The DurationSeconds parameter is separate from the duration of a
console session that you might request using the returned credentials.
The request to the federation endpoint for a console sign-in token takes
a SessionDuration parameter that specifies the maximum length of the
console session. For more information, see Creating a URL that Enables Federated Users to Access the Amazon Web Services Management Console
in the IAM User Guide.
