Amazon Cognito

Amazon Cognito is a web service that delivers scoped temporary credentials to mobile devices and other untrusted environments. Amazon Cognito uniquely identifies a device and supplies the user with a consistent identity over the lifetime of an application.

Using Amazon Cognito, you can enable authentication with one or more third-party identity providers (Facebook, Google, or Login with Amazon), and you can also choose to support unauthenticated access from your app. Cognito delivers a unique identifier for each user and acts as an OpenID token provider trusted by AWS Security Token Service (STS) to access temporary, limited-privilege AWS credentials.

To provide end-user credentials, first make an unsigned call to GetId. If the end user is authenticated with one of the supported identity providers, set the Logins map with the identity provider token. GetId returns a unique identifier for the user.

Next, make an unsigned call to GetOpenIdToken, which returns the OpenID token necessary to call STS and retrieve AWS credentials. This call expects the same Logins map as the GetId call, as well as the IdentityID originally returned by GetId . The token returned by GetOpenIdToken can be passed to the STS operation AssumeRoleWithWebIdentity to retrieve AWS credentials.

Returns:

The response from the ListIdentityPools service method, as returned by AmazonCognitoIdentity.

Throws:

InternalErrorException

NotAuthorizedException

mergeDeveloperIdentities

public MergeDeveloperIdentitiesResult mergeDeveloperIdentities(MergeDeveloperIdentitiesRequest mergeDeveloperIdentitiesRequest)

Merges two users having different IdentityId s, existing in the same identity pool, and identified by the same developer provider. You can use this action to request that discrete users be merged and identified as a single user in the Cognito environment. Cognito associates the given source user ( SourceUserIdentifier ) with the IdentityId of the DestinationUserIdentifier . Only developer-authenticated users can be merged. If the users to be merged are associated with the same public provider, but as two different users, an exception will be thrown.

Specified by:

The developer provider is the "domain" by which Cognito will refer to your users.

You can use GetOpenIdTokenForDeveloperIdentity to create a new identity and to link new logins (that is, user credentials issued by a public provider or developer provider) to an existing identity. When you want to create a new identity, the IdentityId should be null. When you want to associate a new login with an existing authenticated/unauthenticated identity, you can do so by providing the existing IdentityId . This API will create the identity in the specified IdentityPoolId .

setEndpoint

public void setEndpoint(String endpoint)

Description copied from interface: AmazonCognitoIdentity

Overrides the default endpoint for this client ("https://cognito-identity.us-east-1.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: "cognito-identity.us-east-1.amazonaws.com/") or a full URL, including the protocol (ex: "https://cognito-identity.us-east-1.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.

Specified by:

setEndpoint in interface AmazonCognitoIdentity

Overrides:

setEndpoint in class AmazonWebServiceClient

Parameters:

endpoint - The endpoint (ex: "cognito-identity.us-east-1.amazonaws.com/") or a full URL, including the protocol (ex: "https://cognito-identity.us-east-1.amazonaws.com/") of the region specific AWS endpoint this client will communicate with.

setEndpoint

public void setEndpoint(String endpoint,
               String serviceName,
               String regionId)
                 throws IllegalArgumentException

Overrides:

setEndpoint in class AmazonWebServiceClient

Throws:

IllegalArgumentException

getCachedResponseMetadata

public 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 the request.

Specified by:

getCachedResponseMetadata in interface AmazonCognitoIdentity

Parameters:

request - The originally executed request

Returns:

The response metadata for the specified request, or null if none is available.
