Interface for accessing AWSSecurityTokenService. AWS Security Token Service

The AWS Security Token Service 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 AWS Security Token Service API.

For more detailed information about using this service, go to Using Temporary Security Credentials .

For information about setting up signatures and authorization through the API, go to Signing AWS API Requests in the AWS General Reference . For general information about the Query API, go to Making Query Requests in Using IAM .

Method Detail

setEndpoint

void setEndpoint(String endpoint)
                 throws IllegalArgumentException
Overrides the default endpoint for this client ("https://sts.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.

Callers can pass in just the endpoint (ex: "sts.amazonaws.com") or a full URL, including the protocol (ex: "https://sts.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.

For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID=3912

This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

Parameters:
endpoint - The endpoint (ex: "sts.amazonaws.com") or a full URL, including the protocol (ex: "https://sts.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
Throws:
IllegalArgumentException - If any problems are detected with the specified endpoint.

setRegion

void setRegion(Region region)
               throws IllegalArgumentException
An alternative to setEndpoint(String), sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.

By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the ClientConfiguration supplied at construction.

This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

Parameters:
region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions) for accessing a given region.
Throws:
IllegalArgumentException - If the given region is null, or if this service isn't available in the given region. See Region.isServiceSupported(String)

Region.getRegion(com.amazonaws.regions.Regions), Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration)

getSessionToken

GetSessionTokenResult getSessionToken(GetSessionTokenRequest getSessionTokenRequest)
                                      throws AmazonServiceException,
                                             AmazonClientException

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 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.

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, between 900 seconds (15 minutes) and 129600 seconds (36 hours); credentials that are created by using account credentials have a maximum duration of 3600 seconds (1 hour).

The permissions that are granted to the federated user are the intersection of the policy that is passed with the GetSessionToken request and policies that are associated with of the entity making the GetSessionToken call.

For more information about using GetSessionToken to create temporary credentials, go to Creating Temporary Credentials to Enable Access for IAM Users in Using IAM .

Parameters:
getSessionTokenRequest - Container for the necessary parameters to execute the GetSessionToken service method on AWSSecurityTokenService.
Returns:
The response from the GetSessionToken service method, as returned by AWSSecurityTokenService.
Throws:
AmazonClientException - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
AmazonServiceException - If an error response is returned by AWSSecurityTokenService indicating either a problem with the data in the request, or a server side issue.

assumeRoleWithWebIdentity

AssumeRoleWithWebIdentityResult assumeRoleWithWebIdentity(AssumeRoleWithWebIdentityRequest assumeRoleWithWebIdentityRequest)
                                                          throws AmazonServiceException,
                                                                 AmazonClientException

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 Login with Amazon, Facebook, or Google. AssumeRoleWithWebIdentity is an API call that 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 or by deploying server-based proxy services that use long-term AWS credentials. For more information, see Creating a Mobile Application with Third-Party Sign-In in AWS Security Token Service .

The temporary security credentials 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. The credentials are valid for the duration that you specified when calling AssumeRoleWithWebIdentity , which can be from 900 seconds (15 minutes) to 3600 seconds (1 hour). By default, the temporary security credentials are valid for 1 hour.

The temporary security credentials that are returned from the AssumeRoleWithWebIdentity response have the permissions that are associated with the access policy of the role being assumed. You can further restrict the permissions of the temporary security credentials by passing a policy in the request. The resulting permissions are an intersection of the role's access policy and the policy that you passed. These policies and any applicable resource-based policies are evaluated when calls to AWS service APIs are made using the temporary security credentials.

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. For more information, see Creating Temporary Security Credentials for Mobile Apps Using Third-Party Identity Providers .

Parameters:
assumeRoleWithWebIdentityRequest - Container for the necessary parameters to execute the AssumeRoleWithWebIdentity service method on AWSSecurityTokenService.
Returns:
The response from the AssumeRoleWithWebIdentity service method, as returned by AWSSecurityTokenService.
Throws:
PackedPolicyTooLargeException
IDPRejectedClaimException
MalformedPolicyDocumentException
InvalidIdentityTokenException
ExpiredTokenException
IDPCommunicationErrorException
AmazonClientException - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
AmazonServiceException - If an error response is returned by AWSSecurityTokenService indicating either a problem with the data in the request, or a server side issue.

getFederationToken

GetFederationTokenResult getFederationToken(GetFederationTokenRequest getFederationTokenRequest)
                                            throws AmazonServiceException,
                                                   AmazonClientException

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 is getting 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.

Note: Do not use this call in mobile applications or client-based web applications that directly get temporary security credentials. For those types of applications, use AssumeRoleWithWebIdentity .

The GetFederationToken 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 specified duration, between 900 seconds (15 minutes) and 129600 seconds (36 hours); credentials that are created by using account credentials have a maximum duration of 3600 seconds (1 hour).

The permissions that are granted to the federated user are the intersection of the policy that is passed with the GetFederationToken request and policies that are associated with of the entity making the GetFederationToken call.

For more information about how permissions work, see Controlling Permissions in Temporary Credentials in Using Temporary Security Credentials . For information about using GetFederationToken to create temporary security credentials, see Creating Temporary Credentials to Enable Access for Federated Users in Using Temporary Security Credentials .

Parameters:
getFederationTokenRequest - Container for the necessary parameters to execute the GetFederationToken service method on AWSSecurityTokenService.
Returns:
The response from the GetFederationToken service method, as returned by AWSSecurityTokenService.
Throws:
PackedPolicyTooLargeException
MalformedPolicyDocumentException
AmazonClientException - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
AmazonServiceException - If an error response is returned by AWSSecurityTokenService indicating either a problem with the data in the request, or a server side issue.

assumeRole

AssumeRoleResult assumeRole(AssumeRoleRequest assumeRoleRequest)
                            throws AmazonServiceException,
                                   AmazonClientException

Returns a set of temporary security credentials (consisting of an access key ID, a secret access key, and a security token) that you can use to access AWS resources that you might not normally have access to. Typically, you use AssumeRole for cross-account access or federation.

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 Roles in Using IAM .

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 Scenarios for Granting Temporary Access in AWS Security Token Service .

The temporary security credentials are valid for the duration that you specified when calling AssumeRole , which can be from 900 seconds (15 minutes) to 3600 seconds (1 hour). The default is 1 hour.

The temporary security credentials that are returned from the AssumeRoleWithWebIdentity response have the permissions that are associated with the access policy of the role being assumed and any policies that are associated with the AWS resource being accessed. You can further restrict the permissions of the temporary security credentials by passing a policy in the request. The resulting permissions are an intersection of the role's access policy and the policy that you passed. These policies and any applicable resource-based policies are evaluated when calls to AWS service APIs are made using the temporary security credentials.

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 IAM role is created. You must also have a policy that allows you to call sts:AssumeRole .

Important: You cannot call Assumerole by using AWS account credentials; access will be denied. You must use IAM user credentials to call AssumeRole .

Parameters:
assumeRoleRequest - Container for the necessary parameters to execute the AssumeRole service method on AWSSecurityTokenService.
Returns:
The response from the AssumeRole service method, as returned by AWSSecurityTokenService.
Throws:
PackedPolicyTooLargeException
MalformedPolicyDocumentException
AmazonClientException - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
AmazonServiceException - If an error response is returned by AWSSecurityTokenService indicating either a problem with the data in the request, or a server side issue.

getSessionToken

GetSessionTokenResult getSessionToken()
                                      throws AmazonServiceException,
                                             AmazonClientException

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 use MFA to protect programmatic calls to specific AWS APIs like Amazon EC2 StopInstances .

The permissions that are granted to the federated user are the intersection of the policy that is passed with the GetSessionToken request and policies that are associated with of the entity making the GetSessionToken call.

For more information about using GetSessionToken to create temporary credentials, go to Creating Temporary Credentials to Enable Access for IAM Users in Using IAM .

Returns:
The response from the GetSessionToken service method, as returned by AWSSecurityTokenService.
Throws:
AmazonClientException - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.
AmazonServiceException - If an error response is returned by AWSSecurityTokenService indicating either a problem with the data in the request, or a server side issue.

shutdown

void shutdown()
Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.


getCachedResponseMetadata

ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.

Parameters:
request - The originally executed request.
Returns:
The response metadata for the specified request, or null if none is available.
