# `public `Guzzle\Service\Resource\Model``
`getOpenIdTokenForDeveloperIdentity( array $args = array() )`

Executes the GetOpenIdTokenForDeveloperIdentity operation.

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 .

You must use AWS Developer credentials to call this API.

#### Examples

- Basic formatting example

      $result = $client->getOpenIdTokenForDeveloperIdentity(array(
          // IdentityPoolId is required
          'IdentityPoolId' => 'string',
          'IdentityId' => 'string',
          // Logins is required
          'Logins' => array(
              // Associative array of custom 'IdentityProviderName' key names
              'IdentityProviderName' => 'string',
              // ... repeated
          ),
          'TokenDuration' => integer,
      ));

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - IdentityPoolId => (string)

    An identity pool ID in the format REGION:GUID.

  - IdentityId => (string)

    A unique identifier in the format REGION:GUID.

  - Logins => (associative-array<string>)

    Associative array of <IdentityProviderName> keys mapping to (string) values. Each array key should be changed to an appropriate <IdentityProviderName>.

    A set of optional name-value pairs that map provider names to provider tokens. Each name-value pair represents a user from a public provider or developer provider. If the user is from a developer provider, the name-value pair will follow the syntax "developer_provider_name": "developer_user_identifier". The developer provider is the "domain" by which Cognito will refer to your users; you provided this domain while creating/updating the identity pool. The developer user identifier is an identifier from your backend that uniquely identifies a user. When you create an identity pool, you can specify the supported logins.

    - <IdentityProviderName> => (string)
  - TokenDuration => (int)

    The expiration time of the token, in seconds. You can specify a custom expiration time for the token so that you can cache it. If you don't provide an expiration time, the token is valid for 15 minutes. You can exchange the token with Amazon STS for temporary AWS credentials, which are valid for a maximum of one hour. The maximum token duration you can set is 24 hours. You should take care in setting the expiration time for a token, as there are significant security implications: an attacker could use a leaked token to access your AWS resources for the token's duration.

#### Returns

``Guzzle\Service\Resource\Model``
Returns a response Model object

- IdentityId => (string)

  A unique identifier in the format REGION:GUID.

- Token => (string)

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - IdentityPoolId => (string)

    An identity pool ID in the format REGION:GUID.

  - IdentityId => (string)

    A unique identifier in the format REGION:GUID.

    A unique ID used by your backend authentication process to identify a user. Typically, a developer identity provider would issue many developer user identifiers, in keeping with the number of users.

  - MaxResults => (int)

    The maximum number of identities to return.

  - NextToken => (string)

    A pagination token. The first call you make will have NextToken set to null. After that the service will return NextToken values as needed. For example, let's say you make a request with MaxResults set to 10, and there are 20 matches in the database. The service will return a pagination token as a part of the response. This token can be used to call the API again and get results starting from the 11th match.

#### Returns

``Guzzle\Service\Resource\Model``
Returns a response Model object

- IdentityId => (string)

  A unique identifier in the format REGION:GUID.

- DeveloperUserIdentifierList => (array<string>)

  This is the list of developer user identifiers associated with an identity ID. Cognito supports the association of multiple developer user identifiers with an identity ID.

- NextToken => (string)

  A pagination token. The first call you make will have NextToken set to null. After that the service will return NextToken values as needed. For example, let's say you make a request with MaxResults set to 10, and there are 20 matches in the database. The service will return a pagination token as a part of the response. This token can be used to call the API again and get results starting from the 11th match.

# `public `Guzzle\Service\Resource\Model``
`mergeDeveloperIdentities( array $args = array() )`

Executes the MergeDeveloperIdentities operation.

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.

You must use AWS Developer credentials to call this API.

#### Examples

- Basic formatting example

      $result = $client->mergeDeveloperIdentities(array(
          // SourceUserIdentifier is required
          'SourceUserIdentifier' => 'string',
          // DestinationUserIdentifier is required
          'DestinationUserIdentifier' => 'string',
          // DeveloperProviderName is required
          'DeveloperProviderName' => 'string',
          // IdentityPoolId is required
          'IdentityPoolId' => 'string',
      ));

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - SourceUserIdentifier => (string)

    User identifier for the source user. The value should be a DeveloperUserIdentifier.

  - DestinationUserIdentifier => (string)

    User identifier for the destination user. The value should be a DeveloperUserIdentifier.

  - DeveloperProviderName => (string)

    The "domain" by which Cognito will refer to your users. This is a (pseudo) domain name that you provide while creating an identity pool. This name acts as a placeholder that allows your backend and the Cognito service to communicate about the developer provider. For the DeveloperProviderName, you can use letters as well as period (.), underscore (_), and dash (-).

  - IdentityPoolId => (string)

    An identity pool ID in the format REGION:GUID.

#### Returns

``Guzzle\Service\Resource\Model``
Returns a response Model object

- IdentityId => (string)

  A unique identifier in the format REGION:GUID.

# `public `Guzzle\Service\Resource\Model``
`setIdentityPoolRoles( array $args = array() )`

Executes the SetIdentityPoolRoles operation.

Sets the roles for an identity pool. These roles are used when making calls to GetCredentialsForIdentity action.

You must use AWS Developer credentials to call this API.

#### Examples

- Basic formatting example

      $result = $client->setIdentityPoolRoles(array(
          // IdentityPoolId is required
          'IdentityPoolId' => 'string',
          // Roles is required
          'Roles' => array(
              // Associative array of custom 'RoleType' key names
              'RoleType' => 'string',
              // ... repeated
          ),
      ));

#### Parameters

$args
  `array`
  $arg Associative array containing the following keys (required keys are bold):
  - IdentityPoolId => (string)

    An identity pool ID in the format REGION:GUID.

  - Roles => (associative-array<string>)

    Associative array of <RoleType> keys mapping to (string) values. Each array key should be changed to an appropriate <RoleType>.

    The map of roles associated with this pool. For a given role, the key will be either "authenticated" or "unauthenticated" and the value will be the Role ARN.

    - <RoleType> => (string)

#### Returns

``Guzzle\Service\Resource\Model``
Returns a response Model object

# `public `Guzzle\Service\Resource\Model``
`unlinkDeveloperIdentity( array $args = array() )`

Executes the UnlinkDeveloperIdentity operation.

Unlinks a DeveloperUserIdentifier from an existing identity. Unlinked developer users will be considered new identities next time they are seen. If, for a given Cognito identity, you remove all federated identities as well as the developer user identifier, the Cognito identity becomes inaccessible.

You must use AWS Developer credentials to call this API.

#### Examples

- Basic formatting example

      $result = $client->unlinkDeveloperIdentity(array(
          // IdentityId is required
          'IdentityId' => 'string',
          // IdentityPoolId is required
          'IdentityPoolId' => 'string',
          // DeveloperProviderName is required
          'DeveloperProviderName' => 'string',
          // DeveloperUserIdentifier is required
          'DeveloperUserIdentifier' => 'string',
      ));

#### Parameters
