Request Syntax

response = client.add_permission(
    TopicArn='string',
    Label='string',
    AWSAccountId=[
        'string',
    ],
    ActionName=[
        'string',
    ]
)
Parameters
  • TopicArn (string) --

    [REQUIRED]

    The ARN of the topic whose access control policy you wish to modify.

  • Label (string) --

    [REQUIRED]

    A unique identifier for the new policy statement.

  • AWSAccountId (list) --

    [REQUIRED]

    The AWS account IDs of the users (principals) who will be given access to the specified actions. The users must have AWS accounts, but do not need to be signed up for this service.

    [REQUIRED]

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

    Valid values: any Amazon SNS action name.

    • (string) --
Returns

None

can_paginate(operation_name)

Check if an operation can be paginated.

Parameters
operation_name (string) -- The operation name. This is the same name as the method name on the client. For example, if the method name is create_foo, and you'd normally invoke the operation as client.create_foo(**kwargs), if the create_foo operation can be paginated, you can use the call client.get_paginator("create_foo").
Returns
True if the operation can be paginated, False otherwise.
check_if_phone_number_is_opted_out(**kwargs)

Accepts a phone number and indicates whether the phone holder has opted out of receiving SMS messages from your account. You cannot send SMS messages to a number that is opted out.

To resume sending messages, you can opt in the number by using the OptInPhoneNumber action.

See also: AWS API Documentation

Request Syntax

response = client.check_if_phone_number_is_opted_out(
    phoneNumber='string'
)
Parameters
phoneNumber (string) --

[REQUIRED]

      • false – The phone number is opted in, meaning you can publish SMS messages to it.
confirm_subscription(**kwargs)

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".

See also: AWS API Documentation

Request Syntax

response = client.confirm_subscription(
    TopicArn='string',
    Token='string',
    AuthenticateOnUnsubscribe='string'

    [REQUIRED]

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

  • Token (string) --

    [REQUIRED]

    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.

{
    'SubscriptionArn': 'string'
}

Response Structure

  • (dict) --

    Response for ConfirmSubscriptions action.

    • SubscriptionArn (string) --

create_platform_application(**kwargs)

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 WNS, PlatformPrincipal is "Package Security Identifier". For MPNS, PlatformPrincipal is "TLS certificate". For Baidu, PlatformPrincipal is "API key".

For APNS/APNS_SANDBOX, PlatformCredential is "private key". For GCM, PlatformCredential is "API key". For ADM, PlatformCredential is "client secret". For WNS, PlatformCredential is "secret key". For MPNS, PlatformCredential is "private key". For Baidu, PlatformCredential is "secret key". 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 . For more information about obtaining the PlatformPrincipal and PlatformCredential for each of the supported push notification services, see Getting Started with Apple Push Notification Service , Getting Started with Amazon Device Messaging , Getting Started with Baidu Cloud Push , Getting Started with Google Cloud Messaging for Android , Getting Started with MPNS , or Getting Started with WNS .

{
    'PlatformApplicationArn': 'string'
}

Response Structure

  • (dict) --

    Response from CreatePlatformApplication action.

    • PlatformApplicationArn (string) --

      PlatformApplicationArn is returned.

create_platform_endpoint(**kwargs)

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 .

See also: AWS API Documentation

Request Syntax

response = client.create_platform_endpoint(

{}

Response Structure

  • (dict) --

    The response for the OptInPhoneNumber action.

publish(**kwargs)

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.

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 for the TargetArn parameter. The EndpointArn is returned when making a call with the CreatePlatformEndpoint action.

For more information about formatting messages, see Send Custom Platform-Specific Payloads in Messages to Mobile Devices .

See also: AWS API Documentation

Request Syntax

response = client.publish(
    TopicArn='string',
    TargetArn='string',
    PhoneNumber='string',
    Message='string',
    Subject='string',
    MessageStructure='string',
    MessageAttributes={
        'string': {
            'DataType': 'string',
            'StringValue': 'string',
            'BinaryValue': b'bytes'
        }
    }
)
Parameters
  • TopicArn (string) --

    The topic you want to publish to.

    If you don't specify a value for the TopicArn parameter, you must specify a value for the PhoneNumber or TargetArn parameters.

  • TargetArn (string) --

    Either TopicArn or EndpointArn, but not both.

    If you don't specify a value for the TargetArn parameter, you must specify a value for the PhoneNumber or TopicArn parameters.

  • PhoneNumber (string) --

    The phone number to which you want to deliver an SMS message. Use E.164 format.

    If you don't specify a value for the PhoneNumber parameter, you must specify a value for the TargetArn or TopicArn parameters.

  • Message (string) --

    [REQUIRED]

    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.

    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

  • MessageAttributes (dict) --

    Message attributes for Publish action.

    • (string) --
      • (dict) --

        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) -- [REQUIRED]

          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 (bytes) --

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

You can override some of these settings for a single message when you use the Publish action with the MessageAttributes.entry.N parameter. For more information, see Sending an SMS Message in the Amazon SNS Developer Guide .

See also: AWS API Documentation

Request Syntax

response = client.set_sms_attributes(
    attributes={
        'string': 'string'
    }
)
Parameters
attributes (dict) --

[REQUIRED]

The default settings for sending SMS messages from your account. You can set values for the following attribute names:

MonthlySpendLimit – The maximum amount in USD that you are willing to spend each month to send SMS messages. When Amazon SNS determines that sending an SMS message would incur a cost that exceeds this limit, it stops sending SMS messages within minutes.

Warning

Amazon SNS stops sending SMS messages within minutes of the limit being crossed. During that interval, if you continue to send SMS messages, you will incur costs that exceed your limit.

By default, the spend limit is set to the maximum allowed by Amazon SNS. If you want to exceed the maximum, contact AWS Support or your AWS sales representative for a service limit increase.

DeliveryStatusIAMRole – The ARN of the IAM role that allows Amazon SNS to write logs about SMS deliveries in CloudWatch Logs. For each SMS message that you send, Amazon SNS writes a log that includes the message price, the success or failure status, the reason for failure (if the message failed), the message dwell time, and other information.

DeliveryStatusSuccessSamplingRate – The percentage of successful SMS deliveries for which Amazon SNS will write logs in CloudWatch Logs. The value can be an integer from 0 - 100. For example, to write logs only for failed deliveries, set this value to 0 . To write logs for 10% of your successful deliveries, set it to 10 .

DefaultSenderID – A string, such as your business brand, that is displayed as the sender on the receiving device. Support for sender IDs varies by country. The sender ID can be 1 - 11 alphanumeric characters, and it must contain at least one letter.

DefaultSMSType – The type of SMS message that you will send by default. You can assign the following values:

  • Promotional – (Default) Noncritical messages, such as marketing messages. Amazon SNS optimizes the message delivery to incur the lowest cost.
  • Transactional – Critical messages that support customer transactions, such as one-time passcodes for multi-factor authentication. Amazon SNS optimizes the message delivery to achieve the highest reliability.
UsageReportS3Bucket – The name of the Amazon S3 bucket to receive daily SMS usage reports from Amazon SNS. Each day, Amazon SNS will deliver a usage report as a CSV file to the bucket. The report includes the following information for each SMS message that was successfully delivered by your account:
  • Time that the message was published (in UTC)
  • Message ID
  • Destination phone number
  • Message type
  • Delivery status
  • Message price (in USD)
  • Part number (a message is split into multiple parts if it is too long for a single message)
  • Total number of parts

To receive the report, the bucket must have a policy that allows the Amazon SNS service principle to perform the s3:PutObject and s3:GetBucketLocation actions.

For an example bucket policy and usage report, see Monitoring SMS Activity in the Amazon SNS Developer Guide .

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

create_platform_application(**kwargs)

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 WNS, PlatformPrincipal is "Package Security Identifier". For MPNS, PlatformPrincipal is "TLS certificate". For Baidu, PlatformPrincipal is "API key".

For APNS/APNS_SANDBOX, PlatformCredential is "private key". For GCM, PlatformCredential is "API key". For ADM, PlatformCredential is "client secret". For WNS, PlatformCredential is "secret key". For MPNS, PlatformCredential is "private key". For Baidu, PlatformCredential is "secret key". 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 . For more information about obtaining the PlatformPrincipal and PlatformCredential for each of the supported push notification services, see Getting Started with Apple Push Notification Service , Getting Started with Amazon Device Messaging , Getting Started with Baidu Cloud Push , Getting Started with Google Cloud Messaging for Android , Getting Started with MPNS , or Getting Started with WNS .

create_platform_endpoint(**kwargs)

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 .

publish(**kwargs)

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.

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 for the TargetArn parameter. The EndpointArn is returned when making a call with the CreatePlatformEndpoint action.

For more information about formatting messages, see Send Custom Platform-Specific Payloads in Messages to Mobile Devices .

See also: AWS API Documentation

Request Syntax

response = platform_endpoint.publish(
    TopicArn='string',
    PhoneNumber='string',
    Message='string',
    Subject='string',
    MessageStructure='string',
    MessageAttributes={
        'string': {
            'DataType': 'string',
            'StringValue': 'string',
            'BinaryValue': b'bytes'
        }
    }
)
Parameters
  • TopicArn (string) --

    The topic you want to publish to.

    If you don't specify a value for the TopicArn parameter, you must specify a value for the PhoneNumber or TargetArn parameters.

  • PhoneNumber (string) --

    The phone number to which you want to deliver an SMS message. Use E.164 format.

    If you don't specify a value for the PhoneNumber parameter, you must specify a value for the TargetArn or TopicArn parameters.

  • Message (string) --

    [REQUIRED]

    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.

    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

  • MessageAttributes (dict) --

    Message attributes for Publish action.

    • (string) --
      • (dict) --

        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) -- [REQUIRED]

          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 (bytes) --

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

Return type

dict

Returns

Response Syntax

{
    'MessageId': 'string'
}

class SNS.Topic(arn)

A resource representing an Amazon Simple Notification Service (SNS) Topic:

import boto3

sns = boto3.resource('sns')
topic = sns.Topic('arn')
Parameters
arn (string) -- The Topic's arn identifier. This must be set.

These are the resource's available identifiers:

These are the resource's available attributes:

These are the resource's available actions:

These are the resource's available collections:

Identifiers

Identifiers are properties of a resource that are set upon instantation of the resource. For more information about identifiers refer to the Resources Introduction Guide.

arn

(string) The Topic's arn identifier. This must be set.

Attributes

Attributes provide access to the properties of a resource. Attributes are lazy-loaded the first time one is accessed via the load() method. For more information about attributes refer to the Resources Introduction Guide.

attributes
  • (dict) --

    A map of the topic's attributes. Attributes in this map include the following:

    • TopicArn -- the topic's ARN
    • Owner -- the AWS account ID of the topic's owner
    • Policy -- the JSON serialization of the topic's access control policy
    • DisplayName -- the human-readable name used in the "From" field for notifications to email and email-json endpoints
    • SubscriptionsPending -- the number of subscriptions pending confirmation on this topic
    • SubscriptionsConfirmed -- the number of confirmed subscriptions on this topic
    • SubscriptionsDeleted -- the number of deleted subscriptions on this topic
    • DeliveryPolicy -- the JSON serialization of the topic's delivery policy
    • EffectiveDeliveryPolicy -- the JSON serialization of the effective delivery policy that takes into account system defaults
    • (string) --
      • (string) --

Actions

Actions call operations on resources. They may automatically handle the passing in of arguments set from identifiers and some attributes. For more information about actions refer to the Resources Introduction Guide.

add_permission(**kwargs)

Adds a statement to a topic's access control policy, granting access for the specified AWS accounts to the specified actions.

See also: AWS API Documentation

Request Syntax

response = topic.add_permission(
    Label='string',
    AWSAccountId=[
        'string',
    ],
    ActionName=[
        'string',
    ]
)
Parameters
  • Label (string) --

    [REQUIRED]

    A unique identifier for the new policy statement.

  • AWSAccountId (list) --

    [REQUIRED]

    The AWS account IDs of the users (principals) who will be given access to the specified actions. The users must have AWS accounts, but do not need to be signed up for this service.

    • (string) --
  • ActionName (list) --

    [REQUIRED]

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

    Valid values: any Amazon SNS action name.

    • (string) --
Returns

None

confirm_subscription(**kwargs)

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".

See also: AWS API Documentation

Request Syntax

subscription = topic.confirm_subscription(
    Token='string',
    AuthenticateOnUnsubscribe='string'
)
Parameters
  • Token (string) --

    [REQUIRED]

    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.
Return type

sns.Subscription

Returns

Subscription resource

delete()

Deletes a topic and all its subscriptions. Deleting a topic might prevent some messages previously sent to the topic from being delivered to subscribers. This action is idempotent, so deleting a topic that does not exist does not result in an error.

See also: AWS API Documentation

Request Syntax

response = topic.delete()
Returns
None
get_available_subresources()

Returns a list of all the available sub-resources for this Resource.

Returns
A list containing the name of each sub-resource for this resource
Return type
list of str
load()

Calls SNS.Client.get_topic_attributes() to update the attributes of the Topic resource. Note that the load and reload methods are the same method and can be used interchangeably.

See also: AWS API Documentation

Request Syntax

topic.load()
Returns
None
publish(**kwargs)

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.

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 for the TargetArn parameter. The EndpointArn is returned when making a call with the CreatePlatformEndpoint action.

For more information about formatting messages, see Send Custom Platform-Specific Payloads in Messages to Mobile Devices .

See also: AWS API Documentation

Request Syntax

response = topic.publish(
    TargetArn='string',
    PhoneNumber='string',
    Message='string',
    Subject='string',
    MessageStructure='string',
    MessageAttributes={
        'string': {
            'DataType': 'string',
            'StringValue': 'string',
            'BinaryValue': b'bytes'
        }
    }
)
Parameters
  • TargetArn (string) --

    Either TopicArn or EndpointArn, but not both.

    If you don't specify a value for the TargetArn parameter, you must specify a value for the PhoneNumber or TopicArn parameters.

  • PhoneNumber (string) --

    The phone number to which you want to deliver an SMS message. Use E.164 format.

    If you don't specify a value for the PhoneNumber parameter, you must specify a value for the TargetArn or TopicArn parameters.

  • Message (string) --

    [REQUIRED]

    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.

    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

  • MessageAttributes (dict) --

    Message attributes for Publish action.

    • (string) --
      • (dict) --

        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) -- [REQUIRED]

          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 (bytes) --

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