Receive and verify AWS SNS (Amazon Simple Notification Service) webhooks over HTTP/HTTPS. Use when setting up an SNS HTTP subscription endpoint, confirming a subscription (SubscriptionConfirmation / SubscribeURL), verifying SNS message signatures (SigningCertURL, SignatureVersion 1 SHA1 / 2 SHA256), or handling Notification and UnsubscribeConfirmation messages.

AWS SNS Webhooks

When to Use This Skill

  • How do I receive AWS SNS messages at an HTTP/HTTPS endpoint?
  • How do I confirm an SNS subscription (SubscriptionConfirmation / SubscribeURL)?
  • How do I verify an SNS message signature?
  • Why is my SNS signature verification failing?
  • How do I handle SNS Notification and UnsubscribeConfirmation messages?

How SNS Delivery Differs From HMAC Webhooks

SNS is not a Standard Webhooks / shared-secret HMAC provider. Instead:

  • SNS POSTs a JSON envelope with Content-Type: text/plain. The x-amz-sns-message-type header tells you the type without parsing the body: SubscriptionConfirmation, Notification, or UnsubscribeConfirmation.
  • Authenticity is proven with an RSA signature over specific envelope fields (not the raw body, and not an HMAC). You fetch AWS's public X.509 certificate from SigningCertURL and RSA-verify the base64 Signature.
  • New HTTP subscriptions require a handshake: the first message is a SubscriptionConfirmation — you must GET its SubscribeURL (or call ConfirmSubscription with Token) before SNS sends any notifications.

Verification (core)

Node ships the AWS-official sns-validator (handles SigV1/SigV2, the sns.*.amazonaws.com cert-host check, cert fetch, and RSA verify). Pass the parsed message object:

const MessageValidator = require('sns-validator');
const validator = new MessageValidator(); // defaults enforce sns.<region>.amazonaws.com certs over HTTPS

// message = JSON.parse(rawBody). SNS signs specific envelope fields, not the raw body.
validator.validate(message, (err, msg) => {
  if (err) return res.status(400).send('Invalid signature');
  // msg is verified. Branch on msg.Type / the x-amz-sns-message-type header.
});

Python has no AWS webhook SDK — verify manually. Build the canonical string in byte-sorted field order, one Key\nValue\n pair per field that is present (Message, MessageId, Subject?, Timestamp, TopicArn, Type for a Notification; add SubscribeURL and Token for a SubscriptionConfirmation), then RSA-verify with the cert from SigningCertURL (SHA1 for SignatureVersion 1, SHA256 for 2). See references/verification.md (includes the UnsubscribeConfirmation field-set nuance).

For complete handlers with subscription confirmation, event dispatch, and tests, see:

Message Types

SNS delivers three envelope types (read from the x-amz-sns-message-type header):

TypeSent whenWhat to do
SubscriptionConfirmationYou subscribe an HTTP/S endpointGET the SubscribeURL to confirm
NotificationA message is published to the topicRead Subject / Message and process
UnsubscribeConfirmationThe subscription is deletedVerify; optionally re-subscribe if unexpected

The application payload you care about is the Message string inside a Notification (often itself JSON your publisher chose). SNS does not define business event names — those live in your Message body.

Full message formats: Parsing message formats

Environment Variables

# Optional allowlist: reject messages whose TopicArn is not one you expect.
AWS_SNS_TOPIC_ARN=arn:aws:sns:us-east-1:123456789012:MyTopic

There is no signing secret — SNS signatures are verified with AWS's public certificate, so no shared secret is configured. Restrict trust by validating the TopicArn (and, optionally, the certificate host) instead.

Local Development

# Start tunnel (no account needed)
npx hookdeck-cli listen 3000 aws-sns --path /webhooks/aws-sns

We recommend installing the webhook-handler-patterns skill alongside this one for handler sequence, idempotency, error handling, and retry logic. Key references (open on GitHub):

  • Handler sequence — Verify first, parse second, handle idempotently third
  • Idempotency — De-dupe on x-amz-sns-message-id (SNS retries can redeliver)
  • Error handling — Return codes, logging, dead letter queues
  • Retry logic — SNS retry policy and DLQ (RedrivePolicy)

# AWS SNS Webhooks

## When to Use This Skill

- How do I receive AWS SNS messages at an HTTP/HTTPS endpoint?
- How do I confirm an SNS subscription (SubscriptionConfirmation / SubscribeURL)?
- How do I verify an SNS message signature?
- Why is my SNS signature verification failing?
- How do I handle SNS `Notification` and `UnsubscribeConfirmation` messages?

## How SNS Delivery Differs From HMAC Webhooks

SNS is **not** a Standard Webhooks / shared-secret HMAC provider. Instead:

- SNS POSTs a **JSON envelope** with `Content-Type: text/plain`. The
  `x-amz-sns-message-type` header tells you the type without parsing the body:
  `SubscriptionConfirmation`, `Notification`, or `UnsubscribeConfirmation`.
- Authenticity is proven with an **RSA signature over specific envelope fields**
  (not the raw body, and not an HMAC). You fetch AWS's **public X.509
  certificate** from `SigningCertURL` and RSA-verify the base64 `Signature`.
- New HTTP subscriptions require a **handshake**: the first message is a
  `SubscriptionConfirmation` — you must GET its `SubscribeURL` (or call
  `ConfirmSubscription` with `Token`) before SNS sends any notifications.

## Verification (core)

Node ships the AWS-official [`sns-validator`](https://www.npmjs.com/package/sns-validator)
(handles SigV1/SigV2, the `sns.*.amazonaws.com` cert-host check, cert fetch, and
RSA verify). Pass the **parsed** message object:

```javascript
const MessageValidator = require('sns-validator');
const validator = new MessageValidator(); // defaults enforce sns.<region>.amazonaws.com certs over HTTPS

// message = JSON.parse(rawBody). SNS signs specific envelope fields, not the raw body.
validator.validate(message, (err, msg) => {
  if (err) return res.status(400).send('Invalid signature');
  // msg is verified. Branch on msg.Type / the x-amz-sns-message-type header.
});
```

Python has no AWS webhook SDK — verify manually. Build the canonical string in
**byte-sorted field order**, one `Key\nValue\n` pair per field that is present
(`Message`, `MessageId`, `Subject`?, `Timestamp`, `TopicArn`, `Type` for a
Notification; add `SubscribeURL` and `Token` for a SubscriptionConfirmation),
then RSA-verify with the cert from `SigningCertURL` (SHA1 for `SignatureVersion`
1, SHA256 for 2). See [references/verification.md](references/verification.md)
(includes the `UnsubscribeConfirmation` field-set nuance).

## Message Types

SNS delivers three envelope types (read from the `x-amz-sns-message-type` header):

| `Type` | Sent when | What to do |
|--------|-----------|------------|
| `SubscriptionConfirmation` | You subscribe an HTTP/S endpoint | GET the `SubscribeURL` to confirm |
| `Notification` | A message is published to the topic | Read `Subject` / `Message` and process |
| `UnsubscribeConfirmation` | The subscription is deleted | Verify; optionally re-subscribe if unexpected |

The application payload you care about is the `Message` string inside a
`Notification` (often itself JSON your publisher chose). SNS does not define
business event names — those live in your `Message` body.

> **Full message formats**: [Parsing message formats](https://docs.aws.amazon.com/sns/latest/dg/sns-message-and-json-formats.html)

## Environment Variables

```bash
# Optional allowlist: reject messages whose TopicArn is not one you expect.
AWS_SNS_TOPIC_ARN=arn:aws:sns:us-east-1:123456789012:MyTopic
```

There is **no signing secret** — SNS signatures are verified with AWS's public
certificate, so no shared secret is configured. Restrict trust by validating the
`TopicArn` (and, optionally, the certificate host) instead.

## Local Development

```bash
# Start tunnel (no account needed)
npx hookdeck-cli listen 3000 aws-sns --path /webhooks/aws-sns
```
