Overview

Package sts provides the client and types for making API requests to AWS Security Token Service.

The AWS Security Token Service (STS) is a web service that enables you to request temporary, limited-privilege credentials for AWS Identity and Access Management (IAM) users or for users that you authenticate (federated users). This guide provides descriptions of the STS API. For more detailed information about using this service, go to Temporary Security Credentials (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp.html).

As an alternative to using the API, you can use one of the AWS SDKs, which consist of libraries and sample code for various programming languages and platforms (Java, Ruby, .NET, iOS, Android, etc.). The SDKs provide a convenient way to create programmatic access to STS. For example, the SDKs take care of cryptographically signing requests, managing errors, and retrying requests automatically. For information about the AWS SDKs, including how to download and install them, see the Tools for Amazon Web Services page (http://aws.amazon.com/tools/).

For information about setting up signatures and authorization through the API, go to Signing AWS API Requests (http://docs.aws.amazon.com/general/latest/gr/signing_aws_api_requests.html) in the AWS General Reference. For general information about the Query API, go to Making Query Requests (http://docs.aws.amazon.com/IAM/latest/UserGuide/IAM_UsingQueryAPI.html) in Using IAM. For information about using security tokens with other AWS products, go to AWS Services That Work with IAM (http://docs.aws.amazon.com/IAM/latest/UserGuide/reference_aws-services-that-work-with-iam.html) in the IAM User Guide.

If you're new to AWS and need additional technical information about a specific AWS product, you can find the product's technical documentation at http://aws.amazon.com/documentation/ (http://aws.amazon.com/documentation/).

Endpoints

The AWS Security Token Service (STS) has a default endpoint of https://sts.amazonaws.com that maps to the US East (N. Virginia) region. Additional regions are available and are activated by default. For more information, see Activating and Deactivating AWS STS in an AWS Region (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_enable-regions.html) in the IAM User Guide.

For information about STS endpoints, see Regions and Endpoints (http://docs.aws.amazon.com/general/latest/gr/rande.html#sts_region) in the AWS General Reference.

Recording API requests

STS supports AWS CloudTrail, which is a service that records AWS calls for your AWS account and delivers log files to an Amazon S3 bucket. By using information collected by CloudTrail, you can determine what requests were successfully made to STS, who made the request, when it was made, and so on. To learn more about CloudTrail, including how to turn it on and find your log files, see the AWS CloudTrail User Guide (http://docs.aws.amazon.com/awscloudtrail/latest/userguide/what_is_cloud_trail_top_level.html).

See https://docs.aws.amazon.com/goto/WebAPI/sts-2011-06-15 for more information on this service.

See sts package documentation for more information. https://docs.aws.amazon.com/sdk-for-go/api/service/sts/

Using the Client

To contact AWS Security Token Service with the SDK use the New function to create a new service client. With that client you can make API requests to the service. These clients are safe to use concurrently.

See the SDK's documentation for more information on how to use the SDK. https://docs.aws.amazon.com/sdk-for-go/api/

See aws.Config documentation for more information on configuring SDK clients. https://docs.aws.amazon.com/sdk-for-go/api/aws/#Config

See the AWS Security Token Service client STS for more information on creating client for this service. https://docs.aws.amazon.com/sdk-for-go/api/service/sts/#New

Types

type AssumeRoleInput 

type AssumeRoleInput struct {

	// 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 (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html#id_roles_use_view-role-max-session)
	// 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
	// AWS Management Console (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_providers_enable-console-custom-url.html)
	// in the IAM User Guide.
	DurationSeconds *int64 `min:"900" type:"integer"`

	// A unique identifier that is used by third parties when assuming roles in
	// their customers' accounts. For each role that the third party can assume,
	// they should instruct their customers to ensure the role's trust policy checks
	// for the external ID that the third party generated. Each time the third party
	// assumes the role, they should pass the customer's external ID. The external
	// ID is useful in order to help third parties bind a role to the customer who
	// created it. For more information about the external ID, see How to Use an
	// External ID When Granting Access to Your AWS Resources to a Third Party (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create_for-user_externalid.html)
	// in the IAM User Guide.
	//
	// The regex used to validated 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: =,.@:/-
	ExternalId *string `min:"2" type:"string"`

	// An IAM policy in JSON format.
	//
	// This parameter is optional. If you pass a policy, the temporary security
	// credentials that are returned by the operation have the permissions that
	// are allowed by both (the intersection of) the access policy of the role that
	// is being assumed, and the policy that you pass. This gives you a way to further
	// restrict the permissions for the resulting temporary security credentials.
	// You cannot use the passed policy to grant permissions that are in excess
	// of those allowed by the access policy of the role that is being assumed.
	// For more information, see Permissions for AssumeRole, AssumeRoleWithSAML,
	// and AssumeRoleWithWebIdentity (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_control-access_assumerole.html)
	// in the IAM User Guide.
	//
	// The format for this parameter, as described by its regex pattern, is a string
	// of characters up to 2048 characters in length. The characters can be any
	// ASCII character from the space character to the end of the valid character
	// list (\u0020-\u00FF). It can also include the tab (\u0009), linefeed (\u000A),
	// and carriage return (\u000D) characters.
	//
	// The policy plain text must be 2048 bytes or shorter. However, an internal
	// conversion compresses it into a packed binary format with a separate limit.
	// The PackedPolicySize response element indicates by percentage how close to
	// the upper size limit the policy is, with 100% equaling the maximum allowed
	// size.
	Policy *string `min:"1" type:"string"`

	// The Amazon Resource Name (ARN) of the role to assume.
	//
	// RoleArn is a required field
	RoleArn *string `min:"20" type:"string" required:"true"`

	// An identifier for the assumed role session.
	//
	// Use the role session name to uniquely identify a session when the same role
	// is assumed by different principals or for different reasons. In cross-account
	// scenarios, the role session name is visible to, and can be logged by the
	// account that owns the role. The role session name is also used in the ARN
	// of the assumed role principal. This means that subsequent cross-account API
	// requests using the temporary security credentials will expose the role session
	// name to the external account in their CloudTrail logs.
	//
	// 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: =,.@-
	//
	// RoleSessionName is a required field
	RoleSessionName *string `min:"2" type:"string" required:"true"`

	// The identification number of the MFA device that is associated with the user
	// who is making the AssumeRole call. Specify this value if the trust policy
	// of the role being assumed includes a condition that requires MFA authentication.
	// The value is either the serial number for a hardware device (such as GAHT12345678)
	// or an Amazon Resource Name (ARN) for a virtual device (such as arn:aws:iam::123456789012:mfa/user).
	//
	// 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: =,.@-
	SerialNumber *string `min:"9" type:"string"`

	// The value provided by the MFA device, if the trust policy of the role being
	// assumed requires MFA (that is, if the policy includes a condition that tests
	// for MFA). If the role being assumed requires MFA and if the TokenCode value
	// is missing or expired, the AssumeRole call returns an "access denied" error.
	//
	// The format for this parameter, as described by its regex pattern, is a sequence
	// of six numeric digits.
	TokenCode *string `min:"6" type:"string"`
	// contains filtered or unexported fields

Typically, you use AssumeRole for cross-account access or federation. For a comparison of AssumeRole with the other APIs that produce temporary credentials, see Requesting Temporary Security Credentials (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html) and Comparing the AWS STS APIs (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#stsapi_comparison) in the IAM User Guide.

Important: You cannot call AssumeRole by using AWS root account credentials; access is denied. You must use credentials for an IAM user or an IAM role to call AssumeRole.

For cross-account access, imagine that you own multiple accounts and need to access resources in each account. You could create long-term credentials in each account to access those resources. However, managing all those credentials and remembering which one can access which account can be time consuming. Instead, you can create one set of long-term credentials in one account and then use temporary security credentials to access all the other accounts by assuming roles in those accounts. For more information about roles, see IAM Roles (Delegation and Federation) (http://docs.aws.amazon.com/IAM/latest/UserGuide/roles-toplevel.html) in the IAM User Guide.

For federation, you can, for example, grant single sign-on access to the AWS Management Console. If you already have an identity and authentication system in your corporate network, you don't have to recreate user identities in AWS in order to grant those user identities access to AWS. Instead, after a user has been authenticated, you call AssumeRole (and specify the role with the appropriate permissions) to get temporary security credentials for that user. With those temporary security credentials, you construct a sign-in URL that users can use to access the console. For more information, see Common Scenarios for Temporary Credentials (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp.html#sts-introduction) in the IAM User Guide.

By default, the temporary security credentials created by AssumeRole 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 (http://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 operations but does not apply when you use those operations to create a console URL. For more information, see Using IAM Roles (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html) in the IAM User Guide.

The temporary security credentials created by AssumeRole can be used to make API calls to any AWS service with the following exception: you cannot call the STS service's GetFederationToken or GetSessionToken APIs.

Optionally, you can pass an IAM access policy to this operation. If you choose not to pass a policy, the temporary security credentials that are returned by the operation have the permissions that are defined in the access policy of the role that is being assumed. If you pass a policy to this operation, the temporary security credentials that are returned by the operation have the permissions that are allowed by both the access policy of the role that is being assumed, and the policy that you pass. This gives you a way to further restrict the permissions for the resulting temporary security credentials. You cannot use the passed policy to grant permissions that are in excess of those allowed by the access policy of the role that is being assumed. For more information, see Permissions for AssumeRole, AssumeRoleWithSAML, and AssumeRoleWithWebIdentity (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_control-access_assumerole.html) in the IAM User Guide.

To assume a role, your AWS account must be trusted by the role. The trust relationship is defined in the role's trust policy when the role is created. That trust policy states which accounts are allowed to delegate access to this account's role.

The user who wants to access the role must also have permissions delegated from the role's administrator. If the user is in a different account than the role, then the user's administrator must attach a policy that allows the user to call AssumeRole on the ARN of the role in the other account. If the user is in the same account as the role, then you can either attach a policy to the user (identical to the previous different account user), or you can add the user as a principal directly in the role's trust policy. In this case, the trust policy acts as the only resource-based policy in IAM, and users in the same account as the role do not need explicit permission to assume the role. For more information about trust policies and resource-based policies, see IAM Policies (http://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html) in the IAM User Guide.

Using MFA with AssumeRole

You can optionally include multi-factor authentication (MFA) information when you call AssumeRole. This is useful for cross-account scenarios in which you want to make sure that the user who is assuming the role has been authenticated using an AWS MFA device. In that scenario, the trust policy of the role being assumed includes a condition that tests for MFA authentication; if the caller does not include valid MFA information, the request to assume the role is denied. The condition in a trust policy that tests for MFA authentication might look like the following example.

"Condition": {"Bool": {"aws:MultiFactorAuthPresent": true}}

For more information, see Configuring MFA-Protected API Access (http://docs.aws.amazon.com/IAM/latest/UserGuide/MFAProtectedAPI.html) in the IAM User Guide guide.

To use MFA with AssumeRole, you pass values for the SerialNumber and TokenCode parameters. The SerialNumber value identifies the user's hardware or virtual MFA device. The TokenCode is the time-based one-time password (TOTP) that the MFA devices produces.

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for AWS Security Token Service's API operation AssumeRole for usage and error information.

Returned Error Codes:

  • ErrCodeMalformedPolicyDocumentException "MalformedPolicyDocument" The request was rejected because the policy document was malformed. The error message describes the specific error.

  • ErrCodePackedPolicyTooLargeException "PackedPolicyTooLarge" The request was rejected because the policy document was too large. The error message describes how big the policy document is, in packed form, as a percentage of what the API allows.

  • ErrCodeRegionDisabledException "RegionDisabledException" STS is not activated in the requested region for the account that is being asked to generate credentials. The account administrator must use the IAM console to activate STS in that region. For more information, see Activating and Deactivating AWS STS in an AWS Region (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_enable-regions.html) in the IAM User Guide.

Output:

func (*STS) AssumeRoleRequest 

func (c *STS) AssumeRoleRequest(input *AssumeRoleInput) (req *request.Request, output *AssumeRoleOutput)

AssumeRoleRequest generates a "aws/request.Request" representing the client's request for the AssumeRole operation. The "output" return value will be populated with the request's response once the request completes successfuly.

Use "Send" method on the returned Request to send the API call to the service. the "output" return value is not valid until after Send returns without error.

func (*STS) AssumeRoleWithContext 

func (c *STS) AssumeRoleWithContext(ctx aws.Context, input *AssumeRoleInput, opts ...request.Option) (*AssumeRoleOutput, error)

AssumeRoleWithContext is the same as AssumeRole with the addition of the ability to pass a context and additional request options.

See AssumeRole for details on how to use this API operation.

The context must be non-nil and will be used for request cancellation. If the context is nil a panic will occur. In the future the SDK may create sub-contexts for http.Requests. See https://golang.org/pkg/context/ for more information on using Contexts.

func (*STS) AssumeRoleWithSAML 

func (c *STS) AssumeRoleWithSAML(input *AssumeRoleWithSAMLInput) (*AssumeRoleWithSAMLOutput, error)

AssumeRoleWithSAML API operation for AWS Security Token Service.

Returns a set of temporary security credentials for users who have been authenticated via a SAML authentication response. This operation provides a mechanism for tying an enterprise identity store or directory to role-based AWS access without user-specific credentials or configuration. For a comparison of AssumeRoleWithSAML with the other APIs that produce temporary credentials, see Requesting Temporary Security Credentials (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html) and Comparing the AWS STS APIs (http://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 operation 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 AWS services.

By default, the temporary security credentials created by AssumeRoleWithSAML last for one hour. However, you can use the optional DurationSeconds parameter to specify the duration of your session. Your role session lasts for the duration that you specify, or until the time specified in the SAML authentication response's SessionNotOnOrAfter value, whichever is shorter. You can provide a DurationSeconds 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 (http://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 operations but does not apply when you use those operations to create a console URL. For more information, see Using IAM Roles (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html) in the IAM User Guide.

Optionally, you can pass an IAM access policy to this operation. If you choose not to pass a policy, the temporary security credentials that are returned by the operation have the permissions that are defined in the access policy of the role that is being assumed. If you pass a policy to this operation, the temporary security credentials that are returned by the operation have the permissions that are allowed by the intersection of both the access policy of the role that is being assumed, and the policy that you pass. This means that both policies must grant the permission for the action to be allowed. This gives you a way to further restrict the permissions for the resulting temporary security credentials. You cannot use the passed policy to grant permissions that are in excess of those allowed by the access policy of the role that is being assumed. For more information, see Permissions for AssumeRole, AssumeRoleWithSAML, and AssumeRoleWithWebIdentity (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_control-access_assumerole.html) in the IAM User Guide.

Before your application can call AssumeRoleWithSAML, you must configure your SAML identity provider (IdP) to issue the claims required by AWS. Additionally, you must use AWS Identity and Access Management (IAM) to create a SAML provider entity in your AWS account that represents your identity provider, and create an IAM role that specifies this SAML provider in its trust policy.

Calling AssumeRoleWithSAML does not require the use of AWS security credentials. The identity of the caller is validated by using keys in the metadata document that is uploaded for the SAML provider entity for your identity provider.

Calling AssumeRoleWithSAML can result in an entry in your AWS CloudTrail logs. The entry includes the value in the NameID element of the SAML assertion. We recommend that you use a NameIDType that is not associated with any personally identifiable information (PII). For example, you could instead use the Persistent Identifier (urn:oasis:names:tc:SAML:2.0:nameid-format:persistent).

For more information, see the following resources:

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for AWS Security Token Service's API operation AssumeRoleWithSAML for usage and error information.

Returned Error Codes:

  • ErrCodeMalformedPolicyDocumentException "MalformedPolicyDocument" The request was rejected because the policy document was malformed. The error message describes the specific error.

  • ErrCodePackedPolicyTooLargeException "PackedPolicyTooLarge" The request was rejected because the policy document was too large. The error message describes how big the policy document is, in packed form, as a percentage of what the API allows.

  • ErrCodeIDPRejectedClaimException "IDPRejectedClaim" The identity provider (IdP) reported that authentication failed. This might be because the claim is invalid.

    If this error is returned for the AssumeRoleWithWebIdentity operation, it can also mean that the claim has expired or has been explicitly revoked.

  • ErrCodeInvalidIdentityTokenException "InvalidIdentityToken" The web identity token that was passed could not be validated by AWS. Get a new identity token from the identity provider and then retry the request.

  • ErrCodeExpiredTokenException "ExpiredTokenException" The web identity token that was passed is expired or is not valid. Get a new identity token from the identity provider and then retry the request.

  • ErrCodeRegionDisabledException "RegionDisabledException" STS is not activated in the requested region for the account that is being asked to generate credentials. The account administrator must use the IAM console to activate STS in that region. For more information, see Activating and Deactivating AWS STS in an AWS Region (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_enable-regions.html) in the IAM User Guide.

AssumeRoleWithSAMLWithContext is the same as AssumeRoleWithSAML with the addition of the ability to pass a context and additional request options.

See AssumeRoleWithSAML for details on how to use this API operation.

The context must be non-nil and will be used for request cancellation. If the context is nil a panic will occur. In the future the SDK may create sub-contexts for http.Requests. See https://golang.org/pkg/context/ for more information on using Contexts.

func (*STS) AssumeRoleWithWebIdentity 

func (c *STS) AssumeRoleWithWebIdentity(input *AssumeRoleWithWebIdentityInput) (*AssumeRoleWithWebIdentityOutput, error)

AssumeRoleWithWebIdentity API operation for AWS Security Token Service.

Returns a set of temporary security credentials for users who have been authenticated in a mobile or web application with a web identity provider, such as Amazon Cognito, Login with Amazon, Facebook, Google, or any OpenID Connect-compatible identity provider.

For mobile applications, we recommend that you use Amazon Cognito. You can use Amazon Cognito with the AWS SDK for iOS (http://aws.amazon.com/sdkforios/) and the AWS SDK for Android (http://aws.amazon.com/sdkforandroid/) to uniquely identify a user and supply the user with a consistent identity throughout the lifetime of an application.

To learn more about Amazon Cognito, see Amazon Cognito Overview (http://docs.aws.amazon.com/mobile/sdkforandroid/developerguide/cognito-auth.html#d0e840) in the AWS SDK for Android Developer Guide guide and Amazon Cognito Overview (http://docs.aws.amazon.com/mobile/sdkforios/developerguide/cognito-auth.html#d0e664) in the AWS SDK for iOS Developer Guide.

Calling AssumeRoleWithWebIdentity does not require the use of AWS security credentials. Therefore, you can distribute an application (for example, on mobile devices) that requests temporary security credentials without including long-term AWS credentials in the application, and without deploying server-based proxy services that use long-term AWS 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 APIs that produce temporary credentials, see Requesting Temporary Security Credentials (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html) and Comparing the AWS STS APIs (http://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 AWS service APIs.

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 (http://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 operations but does not apply when you use those operations to create a console URL. For more information, see Using IAM Roles (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html) in the IAM User Guide.

The temporary security credentials created by AssumeRoleWithWebIdentity can be used to make API calls to any AWS service with the following exception: you cannot call the STS service's GetFederationToken or GetSessionToken APIs.

Optionally, you can pass an IAM access policy to this operation. If you choose not to pass a policy, the temporary security credentials that are returned by the operation have the permissions that are defined in the access policy of the role that is being assumed. If you pass a policy to this operation, the temporary security credentials that are returned by the operation have the permissions that are allowed by both the access policy of the role that is being assumed, and the policy that you pass. This gives you a way to further restrict the permissions for the resulting temporary security credentials. You cannot use the passed policy to grant permissions that are in excess of those allowed by the access policy of the role that is being assumed. For more information, see Permissions for AssumeRole, AssumeRoleWithSAML, and AssumeRoleWithWebIdentity (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_control-access_assumerole.html) in the IAM User Guide.

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 AWS 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:

Returned Error Codes:

  • ErrCodeMalformedPolicyDocumentException "MalformedPolicyDocument" The request was rejected because the policy document was malformed. The error message describes the specific error.

  • ErrCodePackedPolicyTooLargeException "PackedPolicyTooLarge" The request was rejected because the policy document was too large. The error message describes how big the policy document is, in packed form, as a percentage of what the API allows.

  • ErrCodeIDPRejectedClaimException "IDPRejectedClaim" The identity provider (IdP) reported that authentication failed. This might be because the claim is invalid.

    If this error is returned for the AssumeRoleWithWebIdentity operation, it can also mean that the claim has expired or has been explicitly revoked.

  • ErrCodeIDPCommunicationErrorException "IDPCommunicationError" The request could not be fulfilled because the non-AWS identity provider (IDP) that was asked to verify the incoming identity token could not be reached. This is often a transient error caused by network conditions. Retry the request a limited number of times so that you don't exceed the request rate. If the error persists, the non-AWS identity provider might be down or not responding.

  • ErrCodeInvalidIdentityTokenException "InvalidIdentityToken" The web identity token that was passed could not be validated by AWS. Get a new identity token from the identity provider and then retry the request.

  • ErrCodeExpiredTokenException "ExpiredTokenException" The web identity token that was passed is expired or is not valid. Get a new identity token from the identity provider and then retry the request.

  • ErrCodeRegionDisabledException "RegionDisabledException" STS is not activated in the requested region for the account that is being asked to generate credentials. The account administrator must use the IAM console to activate STS in that region.

AssumeRoleWithWebIdentityWithContext is the same as AssumeRoleWithWebIdentity with the addition of the ability to pass a context and additional request options.

See AssumeRoleWithWebIdentity for details on how to use this API operation.

The context must be non-nil and will be used for request cancellation. If the context is nil a panic will occur. In the future the SDK may create sub-contexts for http.Requests. See https://golang.org/pkg/context/ for more information on using Contexts.

func (*STS) DecodeAuthorizationMessage 

func (c *STS) DecodeAuthorizationMessage(input *DecodeAuthorizationMessageInput) (*DecodeAuthorizationMessageOutput, error)

DecodeAuthorizationMessage API operation for AWS Security Token Service.

Decodes additional information about the authorization status of a request from an encoded message returned in response to an AWS request.

For example, if a user is not authorized to perform an action that he or she has requested, the request returns a Client.UnauthorizedOperation response (an HTTP 403 response). Some AWS actions additionally return an encoded message that can provide details about this authorization failure.

Only certain AWS actions return an encoded authorization message. The documentation for an individual action indicates whether that action returns an encoded message in addition to returning an HTTP code.

The message is encoded because the details of the authorization status can constitute privileged information that the user who requested the action should not see. To decode an authorization status message, a user must be granted permissions via an IAM policy to request the DecodeAuthorizationMessage (sts:DecodeAuthorizationMessage) action.

The decoded message includes the following type of information:

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

Output:

func (*STS) DecodeAuthorizationMessageRequest 

func (c *STS) DecodeAuthorizationMessageRequest(input *DecodeAuthorizationMessageInput) (req *request.Request, output *DecodeAuthorizationMessageOutput)

DecodeAuthorizationMessageRequest generates a "aws/request.Request" representing the client's request for the DecodeAuthorizationMessage operation. The "output" return value will be populated with the request's response once the request completes successfuly.

Use "Send" method on the returned Request to send the API call to the service. the "output" return value is not valid until after Send returns without error.

See DecodeAuthorizationMessage for more information on using the DecodeAuthorizationMessage API call, and error handling.

This method is useful when you want to inject custom logic or configuration into the SDK's request lifecycle. Such as custom headers, or retry logic. 

// Example sending a request using the DecodeAuthorizationMessageRequest method.
req, resp := client.DecodeAuthorizationMessageRequest(params)

err := req.Send()

func (*STS) GetFederationToken 

func (c *STS) GetFederationToken(input *GetFederationTokenInput) (*GetFederationTokenOutput, error)

GetFederationToken API operation for AWS Security Token Service.

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. Because you must call the GetFederationToken action using the long-term security credentials of an IAM user, 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 APIs that produce temporary credentials, see Requesting Temporary Security Credentials (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html) and Comparing the AWS STS APIs (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#stsapi_comparison) in the IAM User Guide.

If you are creating 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, 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 (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_assumerolewithwebidentity).

The GetFederationToken action must be called by using the long-term AWS security credentials of an IAM user. You can also call GetFederationToken using the security credentials of an AWS root account, but we do not recommended it. Instead, we recommend that you create an IAM user for the purpose of the proxy application and then attach a policy to the IAM user that limits federated users to only the actions and resources that they need access to. For more information, see IAM Best Practices (http://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html) in the IAM User Guide.

The temporary security credentials that are obtained by using the long-term credentials of an IAM user are valid for the specified duration, from 900 seconds (15 minutes) up to a maximium of 129600 seconds (36 hours). The default is 43200 seconds (12 hours). Temporary credentials that are obtained by using AWS root account credentials have a maximum duration of 3600 seconds (1 hour).

The temporary security credentials created by GetFederationToken can be used to make API calls to any AWS service with the following exceptions:

  • You cannot use these credentials to call any IAM APIs.

  • You cannot call any STS APIs except GetCallerIdentity.

Permissions

The permissions for the temporary security credentials returned by GetFederationToken are determined by a combination of the following:

  • The policy or policies that are attached to the IAM user whose credentials are used to call GetFederationToken.

  • The policy that is passed as a parameter in the call.

The passed policy is attached to the temporary security credentials that result from the GetFederationToken API call--that is, to the federated user. When the federated user makes an AWS request, AWS evaluates the policy attached to the federated user in combination with the policy or policies attached to the IAM user whose credentials were used to call GetFederationToken. AWS allows the federated user's request only when both the federated user and the IAM user are explicitly allowed to perform the requested action. The passed policy cannot grant more permissions than those that are defined in the IAM user policy.

A typical use case is that the permissions of the IAM user whose credentials are used to call GetFederationToken are designed to allow access to all the actions and resources that any federated user will need. Then, for individual users, you pass a policy to the operation that scopes down the permissions to a level that's appropriate to that individual user, using a policy that allows only a subset of permissions that are granted to the IAM user.

If you do not pass a policy, the resulting temporary security credentials have no effective permissions. The only exception is when the temporary security credentials are used to access a resource that has a resource-based policy that specifically allows the federated user to access the resource.

For more information about how permissions work, see Permissions for GetFederationToken (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_control-access_getfederationtoken.html). For information about using GetFederationToken to create temporary security credentials, see GetFederationToken—Federation Through a Custom Identity Broker (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_getfederationtoken).

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.

See the AWS API reference guide for AWS Security Token Service's API operation GetFederationToken for usage and error information.

Returned Error Codes:

  • ErrCodeMalformedPolicyDocumentException "MalformedPolicyDocument" The request was rejected because the policy document was malformed. The error message describes the specific error.

  • ErrCodePackedPolicyTooLargeException "PackedPolicyTooLarge" The request was rejected because the policy document was too large. The error message describes how big the policy document is, in packed form, as a percentage of what the API allows.

  • ErrCodeRegionDisabledException "RegionDisabledException" STS is not activated in the requested region for the account that is being asked to generate credentials. The account administrator must use the IAM console to activate STS in that region. For more information, see Activating and Deactivating AWS STS in an AWS Region (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_enable-regions.html) in the IAM User Guide.

func (*STS) GetSessionToken 

func (c *STS) GetSessionToken(input *GetSessionTokenInput) (*GetSessionTokenOutput, error)

GetSessionToken API operation for AWS Security Token Service.

Returns a set of temporary credentials for an AWS account or IAM user. The credentials consist of an access key ID, a secret access key, and a security token. Typically, you use GetSessionToken if you want to use MFA to protect programmatic calls to specific AWS APIs like Amazon EC2 StopInstances. MFA-enabled IAM users would need to call GetSessionToken and submit an MFA code that is associated with their MFA device. Using the temporary security credentials that are returned from the call, IAM users can then make programmatic calls to APIs that require MFA authentication. If you do not supply a correct MFA code, then the API returns an access denied error. For a comparison of GetSessionToken with the other APIs that produce temporary credentials, see Requesting Temporary Security Credentials (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html) and Comparing the AWS STS APIs (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#stsapi_comparison) in the IAM User Guide.

The GetSessionToken action must be called by using the long-term AWS security credentials of the AWS account or an IAM user. Credentials that are created by IAM users are valid for the duration that you specify, from 900 seconds (15 minutes) up to a maximum of 129600 seconds (36 hours), with a default of 43200 seconds (12 hours); credentials that are created by using account credentials can range from 900 seconds (15 minutes) up to a maximum of 3600 seconds (1 hour), with a default of 1 hour.

The temporary security credentials created by GetSessionToken can be used to make API calls to any AWS service with the following exceptions:

  • You cannot call any IAM APIs unless MFA authentication information is included in the request.

  • You cannot call any STS API exceptAssumeRole or GetCallerIdentity.

We recommend that you do not call GetSessionToken with root account credentials. Instead, follow our best practices (http://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#create-iam-users) by creating one or more IAM users, giving them the necessary permissions, and using IAM users for everyday interaction with AWS.

The permissions associated with the temporary security credentials returned by GetSessionToken are based on the permissions associated with account or IAM user whose credentials are used to call the action. If GetSessionToken is called using root account credentials, the temporary credentials have root account permissions. Similarly, if GetSessionToken is called using the credentials of an IAM user, the temporary credentials have the same permissions as the IAM user.

For more information about using GetSessionToken to create temporary credentials, go to Temporary Credentials for Users in Untrusted Environments (http://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_getsessiontoken) in the IAM User Guide.

Returns awserr.Error for service API and SDK errors. Use runtime type assertions with awserr.Error's Code and Message methods to get detailed information about the error.
