Interface for accessing AmazonCognitoIdentity. 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 GetCredentialsForIdentity. This call expects the same Logins map as the GetId call, as well as the IdentityID originally returned by GetId . Assuming your identity pool has been configured via the SetIdentityPoolRoles operation, GetCredentialsForIdentity will return AWS credentials for your use. If your pool has not been configured with SetIdentityPoolRoles , or if you want to follow legacy flow, 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.

If you want to use Amazon Cognito in an Android, iOS, or Unity application, you will probably want to make API calls via the AWS Mobile SDK. To learn more, see the AWS Mobile SDK Developer Guide .

 
 public 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 com.amazonaws.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: "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.
Throws:
java.lang.IllegalArgumentException If any problems are detected with the specified endpoint.
 
     public void setEndpoint(String endpointthrows java.lang.IllegalArgumentException;

    
An alternative to setEndpoint(java.lang.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 com.amazonaws.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.

    public void setRegion(Region regionthrows java.lang.IllegalArgumentException;

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.

Retrieves the IdentityID associated with a DeveloperUserIdentifier or the list of DeveloperUserIdentifier s associated with an IdentityId for an existing identity. Either IdentityID or DeveloperUserIdentifier must not be null. If you supply only one of these values, the other value will be searched in the database and returned as a part of the response. If you supply both, DeveloperUserIdentifier will be matched against IdentityID . If the values are verified against the database, the response returns both values and is the same as the request.

Registers (or retrieves) a Cognito IdentityId and an OpenID Connect token for a user authenticated by your backend authentication process. Supplying multiple logins will create an implicit linked account. You can only specify one developer provider as part of the Logins map, which is linked to the identity pool. 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 .

Parameters:
getOpenIdTokenForDeveloperIdentityRequest Container for the necessary parameters to execute the GetOpenIdTokenForDeveloperIdentity service method on AmazonCognitoIdentity.
Returns:
The response from the GetOpenIdTokenForDeveloperIdentity service method, as returned by AmazonCognitoIdentity.

            throws AmazonServiceExceptionAmazonClientException;

    
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.
    public void shutdown();
    
    
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.
