public interface AmazonCognitoIdentity
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.

void setEndpoint(String endpoint) throws IllegalArgumentException
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.

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.

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
.

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

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.
