# # Spiking-based plasticity rules under stimulation protocols (2 neurons)

In this example, I show the effects of plasticity rules on a single
pre-post connection between the two neurons. The neural activity is
entirely regulated from the outside (e.g. the neurons do not interact
through their weights). This is to better illustrate plasticity rules
in their simplest form.

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](http://docs.aws.amazon.com/sns/latest/dg/SNSMobilePush.html). 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](http://docs.aws.amazon.com/sns/latest/dg/mobile-push-apns.html), [Getting Started with Amazon Device Messaging](http://docs.aws.amazon.com/sns/latest/dg/mobile-push-adm.html), [Getting Started with Baidu Cloud Push](http://docs.aws.amazon.com/sns/latest/dg/mobile-push-baidu.html), [Getting Started with Google Cloud Messaging for Android](http://docs.aws.amazon.com/sns/latest/dg/mobile-push-gcm.html), [Getting Started with MPNS](http://docs.aws.amazon.com/sns/latest/dg/mobile-push-mpns.html), or [Getting Started with WNS](http://docs.aws.amazon.com/sns/latest/dg/mobile-push-wns.html).

# Arguments

# 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](http://docs.aws.amazon.com/sns/latest/dg/SNSMobilePush.html).

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](http://docs.aws.amazon.com/sns/latest/dg/SNSMobilePushBaiduEndpoint.html).

# Arguments

## `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 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 = ::Dict{String,String}`
For a list of attributes, see [SetEndpointAttributes](http://docs.aws.amazon.com/sns/latest/api/API_SetEndpointAttributes.html).

# Returns

`CreateEndpointResponse`

# Exceptions

`InvalidParameterException`, `InternalErrorException`, `AuthorizationErrorException` or `NotFoundException`.

# Publish Operation

Sends a message to an Amazon SNS topic or sends a text message (SMS message) directly to a phone number.

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](http://docs.aws.amazon.com/sns/latest/dg/mobile-push-send-custommessage.html).

# Arguments

## `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.

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 (262144 bytes, not 262144 characters).

*   For SMS, each message can contain up to 140 bytes, and the character limit depends on the encoding scheme. 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 the size limit, Amazon SNS sends it as multiple messages, each fitting within the size limit. Messages are not cut off in the middle of a word but on whole-word boundaries. The total size limit for a single SMS publish action is 1600 bytes.

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](http://docs.aws.amazon.com/sns/latest/gsg/Publish.html#sns-message-formatting-by-protocol) in the *Amazon Simple Notification Service Getting Started Guide*.

Valid value: `json`

# SetSMSAttributes Operation

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](http://docs.aws.amazon.com/sns/latest/dg/sms_publish-to-phone.html) in the *Amazon SNS Developer Guide*.

# Arguments

## `attributes = ::Dict{String,String}` -- *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.

**Important**
> 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](https://console.aws.amazon.com/support/home#/case/create?issueType=service-limit-increase&limitType=service-code-sns). 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](http://docs.aws.amazon.com/sns/latest/dg/sms_stats.html) in the *Amazon SNS Developer Guide*.

# Arguments

## `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 AWS Lambda function.

## `Endpoint = ::String`
The endpoint that you want to receive notifications. Endpoints vary by protocol:

*   For the `http` protocol, the endpoint is an URL beginning with "http://"

*   For the `https` protocol, the 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 AWS Lambda function.

## `Attributes = ::Dict{String,String}`
Assigns attributes to the subscription as a map of key-value pairs. You can assign any attribute that is supported by the `SetSubscriptionAttributes` action.

## `ReturnSubscriptionArn = ::Bool`
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 `false`, the response includes the ARN for confirmed subscriptions, but it includes an ARN value of "pending subscription" for subscriptions that are not yet confirmed. A subscription becomes confirmed when the subscriber calls the `ConfirmSubscription` action with a confirmation token.

If you set this parameter to `true`, the response includes the ARN in all cases, even if the subscription is not yet confirmed.

The default value is `false`.
