In sns-example-code-endpoint-java-servlet.md I see:

You can do this by checking that the DNS Name value (DNS Name=sns.us-west-2.amazonaws.com in us-west-2; this will vary by Region) for the Subject Alternative Name field, as presented in the Amazon SNS Certificate, is the same for the received Amazon SNS messages.

Which says the region should be in the DNS Name on the certificate.
In practice I am not seeing the region in the DNS Name. Example test code I executed:

    final URL url =
        new URL(
            "<a url I pulled out of an SNS Message to my server>");
    final InputStream inStream = url.openStream();
    final CertificateFactory cf = CertificateFactory.getInstance("X.509");
    final X509Certificate cert = (X509Certificate) cf.generateCertificate(inStream);
    inStream.close();

    Collection<List<?>> subjectAltNames = null;
    try {
      subjectAltNames = cert.getSubjectAlternativeNames();
    } catch (CertificateParsingException e) {
      System.out.println("CertificateParsingException");
    }
    if (subjectAltNames == null) {
      System.out.println("Certificate did not return subject alternative names");
    } else {
      for (List item : subjectAltNames) {
        System.out.println((int) item.get(0));
        Object data = item.get(1);
        if (data instanceof String) {
          System.out.println((String) data);
        }
      }
    }

Output:

2
sns.amazonaws.com

This issue is about this page https://github.com/awsdocs/amazon-sns-developer-guide/blob/main/doc_source/sms_stats_cloudwatch.md

Would it be possible to document the various fields in the JSON payload?

{
    "notification": {
        "messageId": "34d9b400-c6dd-5444-820d-fbeb0f1f54cf",
        "timestamp": "2016-06-28 00:40:34.558"
    },
    "delivery": {
        "phoneCarrier": "My Phone Carrier",
        "mnc": 270,
        "destination": "+1XXX5550100",
        "priceInUSD": 0.00645,
        "smsType": "Transactional",
        "mcc": 310,
        "providerResponse": "Message has been accepted by phone carrier",
        "dwellTimeMs": 599,
        "dwellTimeMsUntilDeviceAck": 1344
    },
    "status": "SUCCESS"
}

Some are self-explanatory but I have a hard time figuring out mnc or mcc for example

Hi All,

Is there a way to set the SQS attributes from a SNS subscription?

Thanks,
Matthew

The link is dead on the live site:
https://docs.aws.amazon.com/sns/latest/dg/sns-user-notifications-process-overview.html

Redirects to toplevel:
https://docs.aws.amazon.com/sns/latest/dg/sns-mobile-application-as-subscriber.html

The phrasing here seems like it's missing some words, possibly after some editing?

To be clear, Amazon SNS attempts to retry only after a delivery x-amz-sns-message-id header field

Could this description be clarified?

Hi,

I wonder why JSON messages sent by SNS to HTTPS webhooks have a content-type header set to text/plain instead of application/json?

Thanks

doc_source/sns-ttl.md includes a Java SDK example with the TTL message attribute and JSON message structure:

PublishRequest publishRequest = new PublishRequest();
publishRequest.setMessageAttributes(messageAttributes);
String message = "{\"title\":\"Test_Title\",\"description\":\"Test_Description\"}";
publishRequest.setMessage(message);
publishRequest.setMessageStructure("json");

doc_source/sns-message-attributes.md however includes a note:

Note
Message attributes are sent only when the message structure is String, not JSON.

I noticed because I am sending messages in JSON structure and would like to add TTL message attributes for APNS, but I don't know how with this limitation. :)

ARN for fictional queue "MyQueue" in figure 2 of step 4 incorrectly identifies its service as sns.

"Resource":[
      "arn:aws:sns:us-east-2:123456789012:MyQueue"
    ]

The formatting for ARNs is
arn:partition:service:region:account-id:resource-type:resource-id
https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html

Please update to "arn:aws:sqs:us-east-2:123456789012:MyQueue" to reflect resource correctly.

I've send the following in sns;

 {
	"store": {"Type": "String", "Value": "fans"},
	"customer_interests": {"Type": "String.Array", "Value": "[\"baseball\", \"basketball\"]"}
 }
 

And set the following policy:

{
 "store": [
   {
     "exists": true
   }
 ]
}

it does not receive the message.

While this works:

 {
	"store": "fans",
	"customer_interests": {"Type": "String.Array", "Value": "[\"baseball\", \"basketball\"]"}
 }

Is this intended?
