# Creating a subscription to an Amazon SNS topic
<a name="sns-create-subscribe-endpoint-to-topic"></a>

To receive messages published to [a topic](sns-create-topic.md), you must *subscribe* an [endpoint](#sns-endpoints) to the topic. When you subscribe an endpoint to a topic, the endpoint begins to receive messages published to the associated topic.

**Note**  
HTTP(S) endpoints, email addresses, and Amazon resources in other Amazon Web Services accounts require confirmation of the subscription before they can receive messages.

## To subscribe an endpoint to an Amazon SNS topic
<a name="subscribe-topic-aws-console"></a>

Subscribing an endpoint to an Amazon SNS topic enables message delivery to the specified endpoint, ensuring the right systems or users receive notifications when a message is published to the topic. This step is essential for linking the topic to consumers—whether they are applications, email recipients, or other services—allowing for seamless communication across systems.

1. Sign in to the [Amazon SNS console](https://console.amazonaws.cn/sns/home).

1. In the left navigation pane, choose **Subscriptions**.

1. On the **Subscriptions** page, choose **Create subscription**.

1. On the **Create subscription** page, in the **Details** section, do the following:

   1. For **Topic ARN**, choose the Amazon Resource Name (ARN) of a topic. This value is the Amazon ARN that was generated when you created the Amazon SNS topic, for example `arn:aws-cn:sns:us-east-2:123456789012:your_topic`.

   1. For **Protocol**, choose an endpoint type.  The available endpoint types are:
      + [**HTTP/HTTPS**](sns-http-https-endpoint-as-subscriber.md)
      + [**Email/Email-JSON**](sns-email-notifications.md)
      + [****](sns-firehose-as-subscriber.md)
      + [**Amazon SQS**](sns-sqs-as-subscriber.md)
**Note**  
To subscribe to an [SNS FIFO topic](sns-fifo-topics.md), choose this option.
      + [**Amazon Lambda**](sns-lambda-as-subscriber.md)
      + [**Platform application endpoint**](sns-mobile-application-as-subscriber.md)
      + [**SMS**](sns-mobile-phone-number-as-subscriber.md) 

   1. For **Endpoint**, enter the endpoint value, such as an email address or the ARN of an Amazon SQS queue.

   1. Firehose endpoints only: For **Subscription role ARN**, specify the ARN of the IAM role that you created for writing to Firehose delivery streams. For more information, see [Prerequisites for subscribing Firehose delivery streams to Amazon SNS topics](prereqs-kinesis-data-firehose.md).

   1. (Optional) For Firehose, Amazon SQS, HTTP/S endpoints, you can also enable raw message delivery. For more information, see [Amazon SNS raw message delivery](sns-large-payload-raw-message-delivery.md).

   1. (Optional) To configure a filter policy, expand the **Subscription filter policy** section. For more information, see [Amazon SNS subscription filter policies](sns-subscription-filter-policies.md).

   1. (Optional) To enable payload-based filtering, configure `Filter Policy Scope` to `MessageBody`. For more information, see [Amazon SNS subscription filter policy scope](sns-message-filtering-scope.md).

   1. (Optional) To configure a dead-letter queue for the subscription, expand the **Redrive policy (dead-letter queue)** section. For more information, see [Amazon SNS dead-letter queues](sns-dead-letter-queues.md).

   1. Choose **Create subscription**.

      The console creates the subscription and opens the subscription's **Details** page.
