    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.

You must specify PlatformPrincipal and PlatformCredential attributes when using the CreatePlatformApplication action.

PlatformPrincipal and PlatformCredential are received from the notification service.
  • For ADM , PlatformPrincipal is client id and PlatformCredential is client secret .
  • For Baidu , PlatformPrincipal is API key and PlatformCredential is secret key .
  • For APNS and APNS_SANDBOX , PlatformPrincipal is SSL certificate and PlatformCredential is private key .
  • For GCM (Firebase Cloud Messaging), there is no PlatformPrincipal and the PlatformCredential is API key .

See also: AWS API Documentation

Request Syntax

response = client.create_platform_application(
    Name='string',
    Platform='string',
    Attributes={
        'string': 'string'
    }
)
Parameters
  • Name (string) --

    [REQUIRED]

    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) --

    [REQUIRED]

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

create_platform_endpoint(**kwargs)

Creates an endpoint for a device and mobile app on one of the supported push notification services, such as GCM (Firebase Cloud Messaging) and APNS. CreatePlatformEndpoint requires the PlatformApplicationArn that is returned from CreatePlatformApplication . You can use the returned EndpointArn 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 .

Parameters
  • PlatformApplicationArn (string) --

    [REQUIRED]

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

  • Token (string) --

    [REQUIRED]

    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 (Firebase Cloud Messaging) 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.

    The name of the topic you want to create.

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

    For a FIFO (first-in-first-out) topic, the name must end with the .fifo suffix.

  • Attributes (dict) --

    A map of attributes with their corresponding values.

    The following lists the names, descriptions, and values of the special request parameters that the CreateTopic action uses:

    • DeliveryPolicy – The policy that defines how Amazon SNS retries failed deliveries to HTTP/S endpoints.
    • DisplayName – The display name to use for a topic with SMS subscriptions.

    The following attribute applies only to FIFO topics:

    • ContentBasedDeduplication – Enables content-based deduplication. Amazon SNS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message).
    • When ContentBasedDeduplication is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.
    • If the queue has ContentBasedDeduplication set, your MessageDeduplicationId overrides the generated one.
    • (string) --
      • (string) --

publish(**kwargs)

Sends a message to an Amazon SNS topic, a text message (SMS message) directly to a phone number, or a message to a mobile platform endpoint (when you specify the TargetArn ).

If you send a message to a topic, Amazon SNS delivers the message to each endpoint that is subscribed to the topic. The format of the message depends on the notification protocol for each subscribed endpoint.

When a messageId is returned, the message has been saved and Amazon SNS will attempt to deliver it shortly.

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 .

Warning

You can publish messages only to topics and endpoints in the same AWS Region.

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) -- 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.

    If you are publishing to a topic and 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:

    • With the exception of SMS, messages must be UTF-8 encoded strings and at most 256 KB in size (262,144 bytes, not 262,144 characters).
    • For SMS, each message can contain up to 140 characters. This character limit depends on the encoding schema. For example, an SMS message can contain 160 GSM characters, 140 ASCII characters, or 70 UCS-2 characters. If you publish a message that exceeds this size limit, Amazon SNS sends the message as multiple messages, each fitting within the size limit. Messages aren't truncated mid-word but are cut off at whole-word boundaries. The total size limit for a single SMS Publish action is 1,600 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").

    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, String.Array, 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 ASCII Printable Characters .

        • BinaryValue (bytes) --

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

Use this request to set the default settings for sending SMS messages and receiving daily SMS usage reports.

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 raise the limit, submit an SNS Limit Increase case . For New limit value , enter your desired monthly spend limit. In the Use Case Description field, explain that you are requesting an SMS monthly spend 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 .

set_subscription_attributes(**kwargs)

Allows a subscription owner to set an attribute of the subscription to a new value.

See also: AWS API Documentation

Request Syntax

response = client.set_subscription_attributes(
    SubscriptionArn='string',
    AttributeName='string',
    AttributeValue='string'
)
Parameters
  • SubscriptionArn (string) --

    [REQUIRED]

    The ARN of the subscription to modify.

  • AttributeName (string) --

    [REQUIRED]

    A map of attributes with their corresponding values.

    The following lists the names, descriptions, and values of the special request parameters that the SetTopicAttributes action uses:

    • DeliveryPolicy – The policy that defines how Amazon SNS retries failed deliveries to HTTP/S endpoints.
    • FilterPolicy – The simple JSON object that lets your subscriber receive only a subset of messages, rather than receiving every message published to the topic.
    • RawMessageDelivery – When set to true , enables raw message delivery to Amazon SQS or HTTP/S endpoints. This eliminates the need for the endpoints to process JSON formatting, which is otherwise created for Amazon SNS metadata.
    • RedrivePolicy – When specified, sends undeliverable messages to the specified Amazon SQS dead-letter queue. Messages that can't be delivered due to client errors (for example, when the subscribed endpoint is unreachable) or server errors (for example, when the service that powers the subscribed endpoint becomes unavailable) are held in the dead-letter queue for further analysis or reprocessing.
  • AttributeValue (string) -- The new value for the attribute in JSON format.
Returns

None

Exceptions

  • SNS.Client.exceptions.InvalidParameterException
  • SNS.Client.exceptions.FilterPolicyLimitExceededException

    AttributeValue='string'
)
Parameters
  • TopicArn (string) --

    [REQUIRED]

    The ARN of the topic to modify.

  • AttributeName (string) --

    [REQUIRED]

    A map of attributes with their corresponding values.

    The following lists the names, descriptions, and values of the special request parameters that the SetTopicAttributes action uses:

    • DeliveryPolicy – The policy that defines how Amazon SNS retries failed deliveries to HTTP/S endpoints.
    • DisplayName – The display name to use for a topic with SMS subscriptions.
    • Policy – The policy that defines who can access your topic. By default, only the topic owner can publish or subscribe to the topic.

    • KmsMasterKeyId – The ID of an AWS-managed customer master key (CMK) for Amazon SNS or a custom CMK. For more information, see Key Terms . For more examples, see KeyId in the AWS Key Management Service API Reference .

    The following attribute applies only to FIFO topics:

    • ContentBasedDeduplication – Enables content-based deduplication. Amazon SNS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message).
    • When ContentBasedDeduplication is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.
    • If the queue has ContentBasedDeduplication set, your MessageDeduplicationId overrides the generated one.
  • AttributeValue (string) -- The new value for the attribute.

subscribe(**kwargs)

Subscribes an endpoint to an Amazon SNS topic. If the endpoint type is HTTP/S or email, or if the endpoint and the topic are not in the same AWS account, the endpoint owner must the ConfirmSubscription action to confirm the subscription.

You call the ConfirmSubscription action with the token from the subscription response. Confirmation tokens are valid for three days.

This action is throttled at 100 transactions per second (TPS).

Request Syntax

response = client.subscribe(
    TopicArn='string',
    Protocol='string',
    Endpoint='string',
    Attributes={
        'string': 'string'
    },
    ReturnSubscriptionArn=True|False
)
Parameters
  • TopicArn (string) --

    [REQUIRED]

    The ARN of the topic you want to subscribe to.

  • Protocol (string) --

    [REQUIRED]

    The protocol you want to use. Supported protocols include:

    • http – delivery of JSON-encoded message via HTTP POST
    • https – delivery of JSON-encoded message via HTTPS POST
    • email – delivery of message via SMTP
    • email-json – delivery of JSON-encoded message via SMTP
    • sms – delivery of message via SMS
    • sqs – delivery of JSON-encoded message to an Amazon SQS queue
    • application – delivery of JSON-encoded message to an EndpointArn for a mobile app and device.
    • lambda – delivery of JSON-encoded message to an Amazon Lambda function.
  • Endpoint (string) --

    The endpoint that you want to receive notifications. Endpoints vary by protocol:

    • For the http protocol, the (public) endpoint is a URL beginning with http://
    • For the https protocol, the (public) endpoint is a URL beginning with https://
    • For the email protocol, the endpoint is an email address
    • For the email-json protocol, the endpoint is an email address
    • For the sms protocol, the endpoint is a phone number of an SMS-enabled device
    • For the sqs protocol, the endpoint is the ARN of an Amazon SQS queue
    • For the application protocol, the endpoint is the EndpointArn of a mobile app and device.
    • For the lambda protocol, the endpoint is the ARN of an Amazon Lambda function.
  • Attributes (dict) --

    A map of attributes with their corresponding values.

    The following lists the names, descriptions, and values of the special request parameters that the SetTopicAttributes action uses:

    • DeliveryPolicy – The policy that defines how Amazon SNS retries failed deliveries to HTTP/S endpoints.
    • FilterPolicy – The simple JSON object that lets your subscriber receive only a subset of messages, rather than receiving every message published to the topic.
    • RawMessageDelivery – When set to true , enables raw message delivery to Amazon SQS or HTTP/S endpoints. This eliminates the need for the endpoints to process JSON formatting, which is otherwise created for Amazon SNS metadata.
    • RedrivePolicy – When specified, sends undeliverable messages to the specified Amazon SQS dead-letter queue. Messages that can't be delivered due to client errors (for example, when the subscribed endpoint is unreachable) or server errors (for example, when the service that powers the subscribed endpoint becomes unavailable) are held in the dead-letter queue for further analysis or reprocessing.
    • (string) --
      • (string) --
  • ReturnSubscriptionArn (boolean) --

    Sets whether the response from the Subscribe request includes the subscription ARN, even if the subscription is not yet confirmed.

    • If you set this parameter to true , the response includes the ARN in all cases, even if the subscription is not yet confirmed. In addition to the ARN for confirmed subscriptions, the response also includes the pending subscription ARN value for subscriptions that aren't yet confirmed. A subscription becomes confirmed when the subscriber calls the ConfirmSubscription action with a confirmation token.

    The default value is false .

Return type

dict

Returns

Response Syntax

{
    'SubscriptionArn': 'string'
}

Response Structure

  • (dict) --

    Response for Subscribe action.

    • SubscriptionArn (string) --

      The ARN of the subscription if it is confirmed, or the string "pending confirmation" if the subscription requires confirmation. However, if the API request parameter ReturnSubscriptionArn is true, then the value is always the subscription ARN, even if the subscription requires confirmation.

  • SNS.Client.exceptions.InvalidParameterException
  • SNS.Client.exceptions.InternalErrorException
  • SNS.Client.exceptions.NotFoundException
  • SNS.Client.exceptions.AuthorizationErrorException
  • SNS.Client.exceptions.InvalidSecurityException
tag_resource(**kwargs)

Add tags to the specified Amazon SNS topic. For an overview, see Amazon SNS Tags in the Amazon SNS Developer Guide .

When you use topic tags, keep the following guidelines in mind:

  • Adding more than 50 tags to a topic isn't recommended.
  • Tags don't have any semantic meaning. Amazon SNS interprets tags as character strings.
  • Tags are case-sensitive.
  • A new tag with a key identical to that of an existing tag overwrites the existing tag.
  • Tagging actions are limited to 10 TPS per AWS account, per AWS region. If your application requires a higher throughput, file a technical support request .

unsubscribe(**kwargs)

Deletes a subscription. If the subscription requires authentication for deletion, only the owner of the subscription or the topic's owner can unsubscribe, and an AWS signature is required. If the Unsubscribe call does not require authentication and the requester is not the subscription owner, a final cancellation message is delivered to the endpoint, so that the endpoint owner can easily resubscribe to the topic if the Unsubscribe request was unintended.

This action is throttled at 100 transactions per second (TPS).

create_topic(**kwargs)

Creates a topic to which notifications can be published. Users can create at most 100,000 standard topics (at most 1,000 FIFO topics). For more information, see https://aws.amazon.com/sns . This action is idempotent, so if the requester already owns a topic with the specified name, that topic's ARN is returned without creating a new topic.

See also: AWS API Documentation

Request Syntax

topic = sns.create_topic(
    Name='string',
    Attributes={
        'string': 'string'
    },
    Tags=[

        },
    ]
)
Parameters
  • Name (string) --

    [REQUIRED]

    The name of the topic you want to create.

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

    For a FIFO (first-in-first-out) topic, the name must end with the .fifo suffix.

  • Attributes (dict) --

    A map of attributes with their corresponding values.

    The following lists the names, descriptions, and values of the special request parameters that the CreateTopic action uses:

    • DeliveryPolicy – The policy that defines how Amazon SNS retries failed deliveries to HTTP/S endpoints.
    • DisplayName – The display name to use for a topic with SMS subscriptions.
    • FifoTopic – Set to true to create a FIFO topic.
    • Policy – The policy that defines who can access your topic. By default, only the topic owner can publish or subscribe to the topic.

    The following attribute applies only to server-side-encryption :

    • KmsMasterKeyId – The ID of an AWS-managed customer master key (CMK) for Amazon SNS or a custom CMK. For more information, see Key Terms . For more examples, see KeyId in the AWS Key Management Service API Reference .

    The following attribute applies only to FIFO topics:

    • ContentBasedDeduplication – Enables content-based deduplication. Amazon SNS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message).
    • When ContentBasedDeduplication is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.
    • If the queue has ContentBasedDeduplication set, your MessageDeduplicationId overrides the generated one.
    • (string) --
      • (string) --
  • Tags (list) --

PlatformApplication

class SNS.PlatformApplication(arn)

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

import boto3

sns = boto3.resource('sns')
platform_application = sns.PlatformApplication('arn')
Parameters
arn (string) -- The PlatformApplication'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 PlatformApplication'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) --

    Attributes include the following:

    • EventEndpointCreated – Topic ARN to which EndpointCreated event notifications should be sent.
    • EventEndpointDeleted – Topic ARN to which EndpointDeleted event notifications should be sent.
    • EventEndpointUpdated – Topic ARN to which EndpointUpdate event notifications should be sent.
    • EventDeliveryFailure – Topic ARN to which DeliveryFailure event notifications should be sent upon Direct Publish delivery failure (permanent) to one of the application's endpoints.
    • (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.

create_platform_endpoint(**kwargs)

Creates an endpoint for a device and mobile app on one of the supported push notification services, such as GCM (Firebase Cloud Messaging) and APNS. CreatePlatformEndpoint requires the PlatformApplicationArn that is returned from CreatePlatformApplication . You can use the returned EndpointArn 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 .

    • (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.

delete()

Deletes the endpoint for a device and mobile app from Amazon SNS. This action is idempotent. For more information, see Using Amazon SNS Mobile Push Notifications .

When you delete an endpoint that is also subscribed to a topic, then you must also unsubscribe the endpoint from the topic.

See also: AWS API Documentation

Request Syntax

response = platform_endpoint.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_endpoint_attributes() to update the attributes of the PlatformEndpoint resource. Note that the load and reload methods are the same method and can be used interchangeably.

See also: AWS API Documentation

Request Syntax

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

Sends a message to an Amazon SNS topic, a text message (SMS message) directly to a phone number, or a message to a mobile platform endpoint (when you specify the TargetArn ).

If you send a message to a topic, Amazon SNS delivers the message to each endpoint that is subscribed to the topic. The format of the message depends on the notification protocol for each subscribed endpoint.

When a messageId is returned, the message has been saved and Amazon SNS will attempt to deliver it shortly.

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 .

Warning

You can publish messages only to topics and endpoints in the same AWS Region.

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.

    If you are publishing to a topic and 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:

    • With the exception of SMS, messages must be UTF-8 encoded strings and at most 256 KB in size (262,144 bytes, not 262,144 characters).
    • For SMS, each message can contain up to 140 characters. This character limit depends on the encoding schema. For example, an SMS message can contain 160 GSM characters, 140 ASCII characters, or 70 UCS-2 characters. If you publish a message that exceeds this size limit, Amazon SNS sends the message as multiple messages, each fitting within the size limit. Messages aren't truncated mid-word but are cut off at whole-word boundaries. The total size limit for a single SMS Publish action is 1,600 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").

    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, String.Array, 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 ASCII Printable Characters .

        • BinaryValue (bytes) --

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

Return type

dict

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 an Amazon SNS topic, a text message (SMS message) directly to a phone number, or a message to a mobile platform endpoint (when you specify the TargetArn ).

If you send a message to a topic, Amazon SNS delivers the message to each endpoint that is subscribed to the topic. The format of the message depends on the notification protocol for each subscribed endpoint.

When a messageId is returned, the message has been saved and Amazon SNS will attempt to deliver it shortly.

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 .

Warning

You can publish messages only to topics and endpoints in the same AWS Region.

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) -- 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.

    If you are publishing to a topic and 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:

    • With the exception of SMS, messages must be UTF-8 encoded strings and at most 256 KB in size (262,144 bytes, not 262,144 characters).
    • For SMS, each message can contain up to 140 characters. This character limit depends on the encoding schema. For example, an SMS message can contain 160 GSM characters, 140 ASCII characters, or 70 UCS-2 characters. If you publish a message that exceeds this size limit, Amazon SNS sends the message as multiple messages, each fitting within the size limit. Messages aren't truncated mid-word but are cut off at whole-word boundaries. The total size limit for a single SMS Publish action is 1,600 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").

    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, String.Array, 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 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'
}

Response Structure

  • (dict) --

    Response for Publish action.

    • MessageId (string) --

      Unique identifier assigned to the published message.

      Length Constraint: Maximum 100 characters

reload()

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.reload()
Returns
None
remove_permission(**kwargs)

Removes a statement from a topic's access control policy.

See also: AWS API Documentation

Request Syntax

response = topic.remove_permission(
    Label='string'
)
Parameters
Label (string) --

[REQUIRED]

The unique label of the statement you want to remove.

Returns
None
set_attributes(**kwargs)

Allows a topic owner to set an attribute of the topic to a new value.

See also: AWS API Documentation

Request Syntax

response = topic.set_attributes(
    AttributeName='string',
    AttributeValue='string'
)
Parameters
  • AttributeName (string) --

    [REQUIRED]

    A map of attributes with their corresponding values.

    The following lists the names, descriptions, and values of the special request parameters that the SetTopicAttributes action uses:

    • DeliveryPolicy – The policy that defines how Amazon SNS retries failed deliveries to HTTP/S endpoints.
    • DisplayName – The display name to use for a topic with SMS subscriptions.
    • Policy – The policy that defines who can access your topic. By default, only the topic owner can publish or subscribe to the topic.

    The following attribute applies only to server-side-encryption :

    • KmsMasterKeyId – The ID of an AWS-managed customer master key (CMK) for Amazon SNS or a custom CMK. For more information, see Key Terms . For more examples, see KeyId in the AWS Key Management Service API Reference .

    The following attribute applies only to FIFO topics:

    • ContentBasedDeduplication – Enables content-based deduplication. Amazon SNS uses a SHA-256 hash to generate the MessageDeduplicationId using the body of the message (but not the attributes of the message).
    • When ContentBasedDeduplication is in effect, messages with identical content sent within the deduplication interval are treated as duplicates and only one copy of the message is delivered.
    • If the queue has ContentBasedDeduplication set, your MessageDeduplicationId overrides the generated one.
  • AttributeValue (string) -- The new value for the attribute.
Returns

None

subscribe(**kwargs)

Subscribes an endpoint to an Amazon SNS topic. If the endpoint type is HTTP/S or email, or if the endpoint and the topic are not in the same AWS account, the endpoint owner must the ConfirmSubscription action to confirm the subscription.

You call the ConfirmSubscription action with the token from the subscription response. Confirmation tokens are valid for three days.

This action is throttled at 100 transactions per second (TPS).

See also: AWS API Documentation

Request Syntax

subscription = topic.subscribe(
    Protocol='string',
    Endpoint='string',
    Attributes={
        'string': 'string'
    },
    ReturnSubscriptionArn=True|False
)
Parameters
  • Protocol (string) --

    [REQUIRED]

    The protocol you want to use. Supported protocols include:

    • http – delivery of JSON-encoded message via HTTP POST
    • https – delivery of JSON-encoded message via HTTPS POST
    • email – delivery of message via SMTP
    • email-json – delivery of JSON-encoded message via SMTP
    • sms – delivery of message via SMS
    • sqs – delivery of JSON-encoded message to an Amazon SQS queue
    • application – delivery of JSON-encoded message to an EndpointArn for a mobile app and device.
    • lambda – delivery of JSON-encoded message to an Amazon Lambda function.
  • Endpoint (string) --

    The endpoint that you want to receive notifications. Endpoints vary by protocol:

    • For the http protocol, the (public) endpoint is a URL beginning with http://
    • For the https protocol, the (public) endpoint is a URL beginning with https://
    • For the email protocol, the endpoint is an email address
    • For the email-json protocol, the endpoint is an email address
    • For the sms protocol, the endpoint is a phone number of an SMS-enabled device
    • For the sqs protocol, the endpoint is the ARN of an Amazon SQS queue
    • For the application protocol, the endpoint is the EndpointArn of a mobile app and device.
    • For the lambda protocol, the endpoint is the ARN of an Amazon Lambda function.
  • Attributes (dict) --

    A map of attributes with their corresponding values.

    The following lists the names, descriptions, and values of the special request parameters that the SetTopicAttributes action uses:

    • DeliveryPolicy – The policy that defines how Amazon SNS retries failed deliveries to HTTP/S endpoints.
    • FilterPolicy – The simple JSON object that lets your subscriber receive only a subset of messages, rather than receiving every message published to the topic.
    • RawMessageDelivery – When set to true , enables raw message delivery to Amazon SQS or HTTP/S endpoints. This eliminates the need for the endpoints to process JSON formatting, which is otherwise created for Amazon SNS metadata.
    • RedrivePolicy – When specified, sends undeliverable messages to the specified Amazon SQS dead-letter queue. Messages that can't be delivered due to client errors (for example, when the subscribed endpoint is unreachable) or server errors (for example, when the service that powers the subscribed endpoint becomes unavailable) are held in the dead-letter queue for further analysis or reprocessing.
    • (string) --
      • (string) --
  • ReturnSubscriptionArn (boolean) --

    Sets whether the response from the Subscribe request includes the subscription ARN, even if the subscription is not yet confirmed.

    • If you set this parameter to true , the response includes the ARN in all cases, even if the subscription is not yet confirmed. In addition to the ARN for confirmed subscriptions, the response also includes the pending subscription ARN value for subscriptions that aren't yet confirmed. A subscription becomes confirmed when the subscriber calls the ConfirmSubscription action with a confirmation token.

    The default value is false .
