The [**AWS SNS**](https://camel.apache.org/components/4.10.x/aws2-sns-component.html) component allows messages to be sent to an Amazon Simple Notification Topic.

**URI Syntax**: `aws2-sns:topicNameOrArn`

## Main fields

*Path parameters*

| **Name** | **Description** | **Default** | **Type** |
|----------|---------------|------------|----------|
|`topicNameorArn` (producer) | (required) Topic name or ARN |— | String |

*Query parameters*

| **Name** | **Description** | **Default** | **Type** |
|----------|---------------|------------|----------|
| `accessKey`(security) | Amazon AWS access key.| — | String |
| `secretKey`(security) | Amazon AWS secret key.  | — | String |

## Example

<Steps>
<Step>
 The flow starts with a POST request to the `/hello` endpoint with a message in the body.
</Step>
<Step>
 Then, it logs the received content.
</Step>
<Step>
 Next, it publishes the message to AWS SNS:
  - Topic: identified by `{sns-arn}` (Amazon Resource Name of the topic)
  - Region: `us-east-1` (AWS region where the topic is configured)
  - Authentication: `accessKey` and `secretKey` (AWS credentials stored in variables, indicated by double curly braces). Read about [flow variables](/docs/integrations/ipaas-flow-variables) configuration.
  - The body content is published as a message to the topic.
</Step>
</Steps>

```yaml
- from:
            uri: "rest:post:/hello"
            steps:
              - to: "log:info"
              - to:
                  uri: aws2-sns://{sns-arn}
                  parameters:
                    accessKey: "{{ACCESS_KEY}}"
                    secretKey: "{{SECRET_KEY}}"
                    region: us-east-1

```

<Callout type="important" title="IMPORTANT">
When using `accessKey` and `secretKey` as query parameters, you need to pay attention to special characters. If the values contain characters like `+`, `/` or `=`, use the `RAW()` prefix to avoid encoding issues. See an example:

```
uri: aws2-sns://{sns-arn}
parameters: 
   accessKey=RAW(xxxxx)
   secretKey=RAW(yyyyy)
```

Where `xxxxx` and `yyyyy` are the actual key values.

The `RAW()` ensures that Camel treats credentials as literal text, avoiding misinterpretation of special characters. See more details at [How do I configure endpoints?](https://camel.apache.org/manual/faq/how-do-i-configure-endpoints.html)

curl --location --request POST 'https://sensedia-integration-camel-poc.f6g7h8i9j0.integrations-tst.sensedia-eng.com/hello' \
--header 'Content-Type: application/json' \
--data-raw '{
    "message": "test message"
}'
```
