This library provides constructs for adding subscriptions to an Amazon SNS topic.
Subscriptions can be added by calling the `.addSubscription(...)` method on the topic.

## Subscriptions

Subscriptions can be added to the following endpoints:

* HTTPS
* Amazon SQS
* AWS Lambda
* Email

Subscriptions to Amazon SQS and AWS Lambda can be added on topics across regions.

Create an Amazon SNS Topic to add subscriptions.

```python
# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_sns as sns

my_topic = sns.Topic(self, "MyTopic")
```

### HTTPS

Add an HTTP or HTTPS Subscription to your topic:

```python
# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_sns_subscriptions as subscriptions

my_topic.add_subscription(subscriptions.UrlSubscription("https://foobar.com/"))
```

The URL being subscribed can also be [tokens](https://docs.aws.amazon.com/cdk/latest/guide/tokens.html), that resolve
to a URL during deployment. A typical use case is when the URL is passed in as a [CloudFormation
parameter](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html). The
following code defines a CloudFormation parameter and uses it in a URL subscription.

```python
# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
url = CfnParameter(self, "url-param")
my_topic.add_subscription(subscriptions.UrlSubscription(url.value_as_string()))
```

### Amazon SQS

Subscribe a queue to your topic:

```python
# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_sqs as sqs
import aws_cdk.aws_sns_subscriptions as subscriptions

my_queue = sqs.Queue(self, "MyQueue")

my_topic.add_subscription(subscriptions.SqsSubscription(queue))
```

Note that subscriptions of queues in different accounts need to be manually confirmed by
reading the initial message from the queue and visiting the link found in it.

### AWS Lambda

Subscribe an AWS Lambda function to your topic:

```python
# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_lambda as lambda
import aws_cdk.aws_sns_subscriptions as subscriptions

my_function = lambda.Function(self, "Echo",
    handler="index.handler",
    runtime=lambda.Runtime.NODEJS_10_X,
    code=lambda.Code.from_inline(f"exports.handler = {handler.toString()}")
)

my_topic.add_subscription(subscriptions.LambdaSubscription(my_function))
```

### Email

Subscribe an email address to your topic:

```python
# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_sns_subscriptions as subscriptions

my_topic.add_subscription(subscriptions.EmailSubscription("foo@bar.com"))
```

The email being subscribed can also be [tokens](https://docs.aws.amazon.com/cdk/latest/guide/tokens.html), that resolve
to an email address during deployment. A typical use case is when the email address is passed in as a [CloudFormation
parameter](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/parameters-section-structure.html). The
following code defines a CloudFormation parameter and uses it in an email subscription.

```python
# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
email_address = CfnParameter(self, "email-param")
my_topic.add_subscription(subscriptions.EmailSubscription(email_address.value_as_string()))
```

Note that email subscriptions require confirmation by visiting the link sent to the
email address.
