    The action you want to allow for the specified principal(s).

    Valid values: any Amazon SNS action name.

#### Returns

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

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

Executes the AddTagsToResource operation.

#### Parameters

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

Executes the ConfirmSubscription operation.

Verifies an endpoint owner's intent to receive messages by validating the token sent to the endpoint by an earlier Subscribe action. If the token is valid, the action creates a new subscription and returns its Amazon Resource Name (ARN). This call requires an AWS signature only when the AuthenticateOnUnsubscribe flag is set to "true".

#### Examples

- Basic formatting example

      $result = $client->confirmSubscription(array(
          // TopicArn is required
          'TopicArn' => 'string',
          // Token is required
          'Token' => 'string',
          'AuthenticateOnUnsubscribe' => 'string',
      ));

#### Parameters

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

    The ARN of the topic for which you wish to confirm a subscription.

  - Token => (string)

    Short-lived token sent to an endpoint during the Subscribe action.

  - AuthenticateOnUnsubscribe => (string)

    Disallows unauthenticated unsubscribes of the subscription. If the value of this parameter is true and the request has an AWS signature, then only the topic owner and the subscription owner can unsubscribe the endpoint. The unsubscribe action requires AWS authentication.

#### Returns

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

- SubscriptionArn => (string)

  The ARN of the created subscription.

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

Executes the CreatePlatformApplication operation.

Creates a platform application object for one of the supported push notification services, such as APNS and GCM, to which devices and mobile apps may register. You must specify PlatformPrincipal and PlatformCredential attributes when using the CreatePlatformApplication action. The PlatformPrincipal is received from the notification service. For APNS/APNS_SANDBOX, PlatformPrincipal is "SSL certificate". For GCM, PlatformPrincipal is not applicable. For ADM, PlatformPrincipal is "client id". The PlatformCredential is also received from the notification service. For APNS/APNS_SANDBOX, PlatformCredential is "private key". For GCM, PlatformCredential is "API key". For ADM, PlatformCredential is "client secret". The PlatformApplicationArn that is returned when using CreatePlatformApplication is then used as an attribute for the CreatePlatformEndpoint action. For more information, see Using Amazon SNS Mobile Push Notifications.

#### Examples

- Basic formatting example

      $result = $client->createPlatformApplication(array(
          // Name is required
          'Name' => 'string',
          // Platform is required
          'Platform' => 'string',
          // Attributes is required
          'Attributes' => array(
              // Associative array of custom 'String' key names
              'String' => 'string',
              // ... repeated
          ),
      ));

#### Parameters

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

    Application names must be made up of only uppercase and lowercase ASCII letters, numbers, underscores, hyphens, and periods, and must be between 1 and 256 characters long.

  - Platform => (string)

    The following platforms are supported: ADM (Amazon Device Messaging), APNS (Apple Push Notification Service), APNS_SANDBOX, and GCM (Google Cloud Messaging).

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

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

    For a list of attributes, see SetPlatformApplicationAttributes

    - <String> => (string)

#### Returns

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

- PlatformApplicationArn => (string)

  PlatformApplicationArn is returned.

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

Executes the CreatePlatformEndpoint operation.

Creates an endpoint for a device and mobile app on one of the supported push notification services, such as GCM and APNS. CreatePlatformEndpoint requires the PlatformApplicationArn that is returned from CreatePlatformApplication . The EndpointArn that is returned when using CreatePlatformEndpoint can then be used by the Publish action to send a message to a mobile app or by the Subscribe action for subscription to a topic. The CreatePlatformEndpoint action is idempotent, so if the requester already owns an endpoint with the same device token and attributes, that endpoint's ARN is returned without creating a new endpoint. For more information, see Using Amazon SNS Mobile Push Notifications.

When using CreatePlatformEndpoint with Baidu, two attributes must be provided: ChannelId and UserId. The token field must also contain the ChannelId. For more information, see Creating an Amazon SNS Endpoint for Baidu.

#### Examples

- Basic formatting example

      $result = $client->createPlatformEndpoint(array(
          // PlatformApplicationArn is required
          'PlatformApplicationArn' => 'string',
          // Token is required
          'Token' => 'string',
          'CustomUserData' => 'string',
          'Attributes' => array(
              // Associative array of custom 'String' key names
              'String' => 'string',
              // ... repeated
          ),
      ));

#### Parameters

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

    PlatformApplicationArn returned from CreatePlatformApplication is used to create a an endpoint.

  - Token => (string)

    Unique identifier created by the notification service for an app on a device. The specific name for Token will vary, depending on which notification service is being used. For example, when using APNS as the notification service, you need the device token. Alternatively, when using GCM or ADM, the device token equivalent is called the registration ID.

  - CustomUserData => (string)

    Arbitrary user data to associate with the endpoint. Amazon SNS does not use this data. The data must be in UTF-8 format and less than 2KB.

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

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

Executes the Publish operation.

Sends a message to all of a topic's subscribed endpoints. When a messageId is returned, the message has been saved and Amazon SNS will attempt to deliver it to the topic's subscribers shortly. The format of the outgoing message to each subscribed endpoint depends on the notification protocol selected.

To use the Publish action for sending a message to a mobile endpoint, such as an app on a Kindle device or mobile phone, you must specify the EndpointArn. The EndpointArn is returned when making a call with the CreatePlatformEndpoint action. The second example below shows a request and response for publishing to a mobile endpoint.

#### Examples

- Basic formatting example

      $result = $client->publish(array(
          'TopicArn' => 'string',
          'TargetArn' => 'string',
          // Message is required
          'Message' => 'string',
          'Subject' => 'string',
          'MessageStructure' => 'string',
          'MessageAttributes' => array(
              // Associative array of custom 'String' key names
              'String' => array(
                  // DataType is required
                  'DataType' => 'string',
                  'StringValue' => 'string',
                  'BinaryValue' => 'string',
              ),
              // ... repeated
          ),
      ));

#### Parameters

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

    The topic you want to publish to.

  - TargetArn => (string)

    Either TopicArn or EndpointArn, but not both.

  - Message => (string)

    The message you want to send to the topic.

    If you want to send the same message to all transport protocols, include the text of the message as a String value.

    If you want to send different messages for each transport protocol, set the value of the MessageStructure parameter to json and use a JSON object for the Message parameter. See the Examples section for the format of the JSON object.

    Constraints: Messages must be UTF-8 encoded strings at most 256 KB in size (262144 bytes, not 262144 characters).

    JSON-specific constraints:

    - Keys in the JSON object that correspond to supported transport protocols must have simple JSON string values.
    - The values will be parsed (unescaped) before they are used in outgoing messages.
    - Outbound notifications are JSON encoded (meaning that the characters will be reescaped for sending).
    - Values have a minimum length of 0 (the empty string, "", is allowed).
    - Values have a maximum length bounded by the overall message size (so, including multiple protocols may limit message sizes).
    - Non-string values will cause the key to be ignored.
    - Keys that do not correspond to supported transport protocols are ignored.
    - Duplicate keys are not allowed.
    - Failure to parse or validate any key or value in the message will cause the Publish call to return an error (no partial delivery).
  - Subject => (string)

    Optional parameter to be used as the "Subject" line when the message is delivered to email endpoints. This field will also be included, if present, in the standard JSON messages delivered to other endpoints.

    Constraints: Subjects must be ASCII text that begins with a letter, number, or punctuation mark; must not include line breaks or control characters; and must be less than 100 characters long.

  - MessageStructure => (string)

    Set MessageStructure to json if you want to send a different message for each protocol. For example, using one publish action, you can send a short message to your SMS subscribers and a longer message to your email subscribers. If you set MessageStructure to json, the value of the Message parameter must:

    - be a syntactically valid JSON object; and
    - contain at least a top-level JSON key of "default" with a value that is a string.

    You can define other top-level keys that define the message you want to send to a specific transport protocol (e.g., "http").

    For information about sending different messages for each protocol using the AWS Management Console, go to Create Different Messages for Each Protocol in the Amazon Simple Notification Service Getting Started Guide.

    Valid value: json

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

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

    - <attributeName> => (string)
  - MessageAttributes => (associative-array<associative-array>)

    Associative array of <String> keys mapping to (associative-array) values. Each array key should be changed to an appropriate <String>.

    Message attributes for Publish action.

    - <String> => (associative-array)

      The user-specified message attribute value. For string data types, the value attribute has the same restrictions on the content as the message body. For more information, see Publish.

      Name, type, and value must not be empty or null. In addition, the message body should not be empty or null. All parts of the message attribute, including name, type, and value, are included in the message size restriction, which is currently 256 KB (262,144 bytes). For more information, see Using Amazon SNS Message Attributes.

      - DataType => (string)

        Amazon SNS supports the following logical data types: String, Number, and Binary. For more information, see Message Attribute Data Types.

      - StringValue => (string)

        Strings are Unicode with UTF8 binary encoding. For a list of code values, see http://en.wikipedia.org/wiki/ASCII#ASCII_printable_characters.

      - BinaryValue => (string)

        Binary type attributes can store any binary data, for example, compressed data, encrypted data, or images.
